ОглавлениеSUB-FAMILY VESPERTILIONIDÆ.
These bats have simple nostrils, as in the frugivorous ones, with no complications of foliated cutaneous appendages; the muzzle is conical, moderately long, and clad with fur; the ears wide apart; the inner margins springing from the sides, not the top of the head; the tragi are large; eyes usually very small, and the tail, which is long, is wholly included in the membrane.
Dentition (usually): Inc., 2—2/6; can., 1—1/1—1, premol., 3—3/3—3; mol., 3—3/3—3. The upper incisors are small, and placed in pairs near the canines, leaving a gap in the centre. The lower ones sharp-edged and somewhat notched. At birth there are twenty-two teeth, which are shed, and replaced by others, with sixteen additional ones, the adult bat having thirty-eight teeth.
GENUS PLECOTUS.
Ears very large, united at the base; outer margin of the ear conch terminating opposite the base of the tragus, the inner margin with an abrupt rounded projection directed inwards above the base; tragus very large, tapering upwards, with a lobe at the base of the outer margin.
Dentition: Inc., 2—2/6; can., 1—1/1—1; premolars, 2—2/2—2; molars, 3—3/3—3.
The English species P. auritus is very common there, and also in France; its ears are nearly as long as its body, yet, when reposing, they are so folded as to be almost out of sight. The Indian species is only a variety distinguishable by its yet longer ears ("and comparative shortness of the thumbs"—Dobson).
NO. 77. PLECOTUS AURITUS vel HOMOCHROUS.
| Plecotus auritus. |
HABITAT.—The Himalayas and the Khasia Hills.

SIZE.—Head and body, 1·7 inch; ears, 1·55 (ears of English type of same size, 1·4 inch); tail, 1·7 inch. Jerdon gives larger results, but I put more reliance on Dobson's figures.
GENUS VESPERUGO.
Bats with very broad and obtuse muzzles; the glandular prominences much developed between the eyes and the nostrils; crown of the head flat; but what distinguishes it from the following genus, Scotophilus, is the presence of four incisors in the upper jaw, whereas Scotophilus has two only—otherwise the two genera are very similar.
NO. 78. VESPERUGO NOCTULA.
HABITAT.—Nepal.
| Vesperugo noctula. |
DESCRIPTION.—Head broad and flat; ears oval and broad; the outer margin convex, reflected backwards, and forming a thick lobe terminating close to the angle of the mouth; tragus short and curved inwards; muzzle devoid of hair; fur dark reddish brown.

NO. 81. VESPERUGO AFFINIS.
HABITAT.—Burmah (Bhamo, Yunan).
DESCRIPTION (apud Dobson).—Head flat; upper labial glands so developed as to cause a deep depression between them on the face behind the nostrils; ears broad as long from behind; the outer margin extends from the tip to its termination near the corner of the mouth without emargination or lobe; tragus broad; inner margin straight; outer convex; small triangular lobe at base. Fur chocolate brown above, lighter on head and neck; beneath dark brown with lighter tips on the pubes, and along the thighs dirty white or pale buff.
SIZE.—Head and body, 1·9 inch; tail, 1·65 inch.
There is a good figure of the head of this bat in Dobson's Monograph; it was obtained by Dr. J. Anderson at an elevation of 4500 feet at Bhamo.
NO. 82. VESPERUGO PACHYOTIS.
DESCRIPTION.—"This species is readily distinguished by the peculiar thickness of the lower half of the outer side of the ear-conch, which appears as it were excavated out of the thick integument of the neck; tragus short, curved inwards."—Dobson.
This bat is more fully described with three illustrations in Dobson's Monograph; he does not mention where it is found, so it may or it may not be an Indian species.
NO. 83. VESPERUGO ATRATUS. Syn.—NYCTICEJUS ATRATUS.
HABITAT.—Darjeeling.
DESCRIPTION.—Head broad; muzzle obtuse; upper labial glands largely developed; ears large, oval, with rounded tips, which in the natural position of the ears appear acute, owing to the longitudinal folding of the outer side of the conch on the inner, commencing at and almost bisecting the tip (Dobson). Fur long, dense and black; Jerdon says rich dark brown; paler beneath.
SIZE.—Head and body, 1·9 inch; tail, 1·8 inch.

Unites the appearance of a Vespertilio to the dentition of Vesperugo.
NO. 87. VESPERUGO DORMERI.
HABITAT.—Southern India and Bellary Hills.
DESCRIPTION.—Head flat; ears shorter, triangular, with rounded tips; tragus with a small triangular lobe near base of outer margin; fur brown, with ashy tips above, darker brown below, with the terminal third of the hairs white. Dentition approaches the next genus, there being only one pair of unicuspidate upper incisors placed, one by each upper canine.
NO. 88. (VESPERUGO) SCOTOPHILUS SEROTINUS. Syn.—VESPERUGO SEROTINUS. The Silky Bat (Jerdon's No. 35).

SIZE.—Head and body, 2½ inches; tail, 2; wing expanse, 13.
This is a rare bat in India, though Captain Hutton has procured it at Mussoorie. In England it is not uncommon even near London; it flies steadily and rather slow, and is found in ruins, roofs of churches, and sometimes old hollow trees.
NO. 89. (VESPERUGO) SCOTOPHILUS LEISLERI. Syn.—VESPERUGO LEISLERI. The Hairy-armed Bat (Jerdon's No. 36).

SCOTOPHILUS PACHYOMUS. (Jerdon's No. 37)
Synonymous with his No. 35; see Dobson's Monograph.
NO. 90. (VESPERUGO) SCOTOPHILUS COROMANDELIANUS. Syn.—VESPERUGO ABRAMUS; VESPERTILIO COROMANDELICUS. The Coromandel Bat (Jerdon's No. 38).

SIZE.—Two and a-half inches, of which the tail is 1¼; expanse 7–⅔. Jerdon, quoting Tomes, states that this is the same as V. Abramus, but that is the synonym of the last species.
GENUS SCOTOPHILUS.
Muzzle short, bluntly conical, devoid of hair; ears longer than broad; tail shorter than the head and body; wing membrane attached to the base of the toes.
Dentition: Inc., 1—⅙; can., 1—1/1—1; premolars, 1—½—2; molars 3—3/3—3.
Jerdon's formula gives upper incisors 4.
NO. 92. SCOTOPHILUS FULIGINOSUS. The Smoky Bat (Jerdon's No. 40).
HABITAT.—Central Nepal.
DESCRIPTION (apud Hodgson).—"Feet very small, included in the wing membrane nearly to the end of the toes; ears acutely pointed, shorter than the head; muzzle groved, nudish; face sharp; rostrum somewhat recurved; wholly sooty brown; a little smaller than Vesp. formosa."
I cannot find this bat mentioned by any other author, and Jerdon says it does not seem to be recognised.
NO. 93. SCOTOPHILUS TEMMINCKII. Syn.—NYCTICEJUS TEMMINCKII (Jerdon).
| Scotophilus Temminckii. |
HABITAT.—India generally; Burmah and Ceylon.
DESCRIPTION.—Ears short, rounded and narrow; tragus narrow, curved and pointed inwards; muzzle thick, blunt and conical; the fur varies, sometimes dark olive brown, fulvous beneath, and occasionally chestnut, with a paler shade of yellow below.

A very common species, appearing early in the evening. Horsfield says of it that it collects by hundreds in hollow trees, and feeds chiefly on white ants.
NO. 94. SCOTOPHILUS HEATHII.
HABITAT.—India and Ceylon (Rajanpore, Punjab).
DESCRIPTION.—Similar to the above, but longer in all its measurements (Dobson). Judging from drawings, the head and muzzle of this are more in a line than in the last species, the ears project forward, and are also larger, the tragus especially, and there is a greater width between the ears.
SIZE.—Five inches, of which the tail is 2.
NO. 95. SCOTOPHILUS EMARGINATUS.
HABITAT.—India; precise locality unknown.
DESCRIPTION.—Head broad and flat; muzzle obtuse and thick; ears long and large, with rounded tips turning outwards; tragus short; thumb long with a strong claw; wing membrane quite devoid of hair, except on the interfemoral membrane, which is half covered; fur tricolored, first dark chestnut, buff, and then yellowish brown.

DESCRIPTION.—Head broad; muzzle short; ears triangular, erect, with rounded tips, and broadly rounded lobe at the base; tragus narrow, semi-lunate, curved towards the front; fur a light Isabelline brown, spotted with white; a white spot on the centre of the forehead, and from the back of the head down the spine for two-thirds of its length a narrow white streak; on each side of the body two white patches; a broad white collar, or rather demi-collar, from one ear spot to the other, passing under the throat. Dr. Dobson says the position of these patches is very constant, but the size varies, being greatest in individuals of a pale rusty red colour, and these he found always to be males.
SIZE.—Head and body, 3 inches; tail, 2 inches; expanse, 15.
NO. 97. SCOTOPHILUS PALLIDUS.
HABITAT.—Mian Mir, Lahore.
DESCRIPTION.—Head and muzzle as in S. Temminckii; ears slightly shorter than the head; internal basal lobe convex, evenly rounded; tip broadly rounded off; tragus moderately long and rounded at the tip; a prominent triangular lobe at base. Wing membrane from base of toes; lobule at the heel very narrow and long; last rudimentary caudal vertebra free; fur of the body, wings, and interfemoral membrane pale buff throughout.
SIZE.—Head and body, 2 inches; tail, 1·4 inch.
NOCTULINIA NOCTULA. (See ante: Vesperugo noctula—Jerdon's No. 41.)
NYCTICEJUS HEATHII. Large Yellow Bat (Jerdon's No. 42). (See ante: Scotophilus Heathii.)
NYCTICEJUS LUTEUS. The Bengal Yellow Bat (Jerdon's No. 43).
NYCTICEJUS TEMMINCKII. The Common Yellow Bat (Jerdon's No. 44).
Both the above (Nos. 43 and 44) are, according to Dr. Dobson, synonymous with Scotophilus Temminckii, which see.
NYCTICEJUS CASTANEUS. The Chestnut Bat (Jerdon's No. 45).
This is also a variety of Scotophilus Temminckii.
NYCTICEJUS ATRATUS. The Sombre Bat (Jerdon's No. 46). (See ante: Vesperugo atratus.)
NYCTICEJUS CANUS. The Hoary Bat (Jerdon's No. 47). (See ante: Vesperugo lobatus.)
NYCTICEJUS ORNATUS. The Harlequin Bat (Jerdon's No. 48). (See ante: Scotophilus ornatus.)
NO. 98. NYCTICEJUS NIVICOLUS. The Alpine Bat (Jerdon's No. 49).
HABITAT.—Sikim.
DESCRIPTION.—"Head and body above uniform light brown with a slight yellowish shade; underneath, from the throat to the vent, dark grey with a brownish tint, lighter on the sides of the throat. Ears long, attenuated to an obtuse point."—Jerdon.
SIZE.—Head and body, 3 inches; tail, 2 inches; expanse, 19 inches.
This bat was described by Hodgson ('Ann. Mag. Nat. Hist.' 1855), but there is some doubt about it, and it has been classed as a Lasiurus and also with Scot. ornatus and Vesp. formosa, but Jerdon thinks it a distinct species. I cannot find any mention of it in Dobson's monograph.
GENUS HARPIOCEPHALUS.
This is also the genus Murina of Gray. Dr. Dobson explains his acceptance of the former term in the following way: that he first accepted Murina on the score of priority in a paper showing that Harpiocephalus and Murina must be united in a single genus; but finding afterwards that Gray had founded Murina on a specimen of what he believed to be Vesp. suillus (Temm.), but which was in reality a specimen of a very different species from Darjeeling, belonging to the same section of the genus as Vespertilio harpia (Temm.) the type of his genus Harpiocephalus, it remained therefore either to discard both names or to retain Harpiocephalus, in which course he was supported by Professor Peters, to whom he mentioned the facts.
Horsfield's genus Lasiurus is included in this one, though Jerdon considers it distinct from Murina.
Muzzle elongated, conical; nostrils prominent, tubular; produced beyond the upper lip, opening laterally or sublaterally, emarginate between; crown of the head scarcely raised above the face line; ears thin, generally covered with glandular papillæ; tragus long, attenuated towards the tip, and inclined outwards; thumb very large, with a large, strongly curved claw; wings around interfemoral membrane very hairy.—Dobson.
Dentition: Inc., 2—2/6; can. 1—1/1—1; premolars, 2—2/2—2; molars, 3—3/3—3.
NO. 99. HARPIOCEPHALUS HARPIA. Lasiurus Pearsonii (Horsfield) (Jerdon's No. 50).
HABITAT.—Darjeeling and Khasia hills.
DESCRIPTION.—"Fur above very soft, silky, and rather long; colour on the head, neck, and shoulders brownish grey, with a ferruginous cast, variegated with whitish hairs; the rest of the body above, with the base of the membrane, the thighs and the interfemoral membrane, have a deep bay or reddish-brown hue, and delicate hairs of the same colour are scattered over the membrane and project from its border; the body underneath is thickly covered with a grey fur, which is paler on the breast and body; the interfemoral membrane marked with regularly parallel transverse lines" (Horsfield). Ears ovoid; tragus rather long, nearly straight, acute at the tip (Jerdon). Muzzle rather short, obtusely conical; end of nose projecting considerably beyond the lip, consisting of diverging tubular nostrils opening laterally, with a slight emargination between each (Dobson).
| Harpiocephalus harpia. |
SIZE.—Head and body, 3 inches; tail, 1½ inch; expanse, 14. Hodgson, who procured it at Darjeeling, writes of it: "Entire legs and caudal membrane clad in fur like the body, which is thick and woolly. Colour bright rusty above; sooty below, the hairs tipped with hoary."
This bat is, for its size, one of the most powerfully armed with teeth. The skull reminds one of that of a dog or hyæna in miniature; the teeth are very stout, the canines blunt and conical, and the cusps of the molars short and blunt, well coated with enamel; the jaws are correspondingly muscular and adapted to the food of the animal, which consists of hard-shelled beetles, the crushed cases of which have been found in its stomach.
NO. 100. HARPIOCEPHALUS (MURINA) SUILLUS. The Pig-Bat (Jerdon's No. 51).
HABITAT.—Darjeeling (Jerdon); Malayan archipelago.
DESCRIPTION.—Muzzle narrow, elongated; nostrils very prominent, which, viewed from below, resemble in shape a small hour-glass placed horizontally at the extremity of the muzzle; ears moderate, shorter than the head, rounded at the tips; tragus moderately long, attenuated above and slightly curved outwards; fur light greyish-brown; extremities dark brown; beneath light greyish-brown throughout.—Dobson.
SIZE.—Head and body, 1¾ to 2 inches; tail, 1½ inch; expanse 9 to 10.
NO. 101. HARPIOCEPHALUS AURATUS.
HABITAT.—Thibet.
DESCRIPTION.—Head and muzzle as in H. suillus, but the nostrils are differently shaped; each nostril forms a distinct tube directed sublaterally with a circular aperture marked by a very small notch on the outer and upper margin (Dobson). The whole body is thickly clad; the fur on the back is black, with bright golden yellow tips; the back of the fore-arm covered with short golden hair; the hair of the under parts black with silvery tips, whiter on the lower jaw, neck and pubis; the interfemoral membrane is covered with very long hair, which forms a fringe along its free margin extending on the legs and feet, and projecting beyond the toes; underneath short silvery hair.
SIZE.—Head and body 1·4 inch; tail 1·2.
NO. 102. HARPIOCEPHALUS GRISEUS.
HABITAT.—Jeripani, N.W. Himalayas.
DESCRIPTION.—Head and muzzle as in H. suillus; fur above dark brown, with yellowish-brown extremities; beneath similar, but with the extreme points of the hairs ashy.
SIZE.—Head and body, 1·4 inch; tail 1 inch.
This bat was found near Mussoorie by Captain Hutton, who writes that it occurs, but sparingly, on the outer southern range of hills at 5500 feet. It skims close to the ground, and somewhat leisurely over the surface of the crops and grass; and one which flew into his room kept low down, passing under chairs and tables, instead of soaring towards the ceiling, as bats generally do.
NO. 103. HARPIOCEPHALUS LEUCOGASTER.
HABITAT.—N.W. Himalayas, Thibet.
DESCRIPTION.—Head and muzzle as in H. harpia; fur long and dense, above brown with grey bases; underneath whitish; sides light brown. It differs from the next species by a small projecting tooth on the inner margin of the ear conch, by the smaller size of the first upper premolar, and by the colour.—Dobson.
SIZE.—Head and body, 1·9 inch; tail 1·5.
NO. 104. HARPIOCEPHALUS CYCLOTIS.
HABITAT.—Darjeeling, Ceylon.
DESCRIPTION.—Similar to the last, but with round ears; fur bicoloured, the hairs being dark brown at the base, with bright ferruginous tips; below pale brown; the upper surface of the interfemoral membrane and back of the feet covered with hair, which also extends beyond the toes; the first premolar in the upper jaw nearly equal in size to the second, whereas in the last species it is only about three-fourths.
SIZE.—Head and body, 1·7 inch; tail, 1·5.
GENUS KERIVOULA.
DESCRIPTION.—Muzzle long and narrow; skull very concave between the nasal bones and the vertex, so that the crown appears considerably vaulted; ears funnel-shaped and semi-transparent; tragus very long, narrow and pointed; wings very wide; tail longer than head and body, wholly contained within the interfemoral membrane.
Dentition: Inc., 2—2/6; can., 1—1/1—1; premolars, 3—3/3—3; molars, 3—3/3—3.
The generic name of this bat is composed of two Singhalese words—kehel or kela, the plantain, and voulha, which is the Singhalese for bat, the specimen on which Gray founded his genus being the following:—
NO. 105. KERIVOULA PICTA. The Painted Bat (Jerdon's No. 53).
HABITAT.—India generally, Burmah and Ceylon.
DESCRIPTION.—"Fur fine, woolly; above yellowish-red or golden rufous, beneath less brilliant and more yellow; wing membranes inky black, with rich orange stripes along the fingers extending in indentations into the membrane."—Jerdon.
Ears moderate, laid forwards; the tips reach midway between the eyes and the middle of the muzzle; tragus very long and straight; thumb short; wings to the base of the toes.
SIZE.—Head and body, 1½ inch; tail, 1·6 inch; expanse about 10 inches.
This beautiful little bat is found all over India, but is not common; it is occasionally caught in plantain gardens, as it resorts to the leaves of that tree for shelter during the night, and may sometimes be discovered in the folds of a leaf. As Jerdon remarks, it looks more like a butterfly or a moth when disturbed during the day time. Dr. Dobson pertinently observes that the colours of this bat appear to be the result of the "protective mimicry" which we see so often in insects, the Mantidea and other genera, the colours being adapted to their abiding places. He alludes to Mr. Swinhoe's account ('P. Z. S.,' 1862, p. 357) of an allied species:—"The body of this bat was of an orange yellow, but the wings were painted with orange yellow and black. It was caught suspended head downwards on a cluster of the round fruit of the longan tree. (Nephelium [Scytalia] longanum) [the ash phul of Bengal]. Now this tree is an evergreen, and all the year through some portion of its foliage is undergoing decay, the particular leaves being in such a stage partially orange and black; this bat can therefore at all seasons suspend from its branches and elude its enemies by its resemblance to the leaf of the tree." This bat was named by Pallas Vespertilio pictus. Boddaert in 1785 termed it Vesp. kerivoula, and Gray afterwards took the second specific name for that of the genus, leaving the first as it is.
KERIVOULA PALLIDA. (Jerdon's No. 54.)
This is synonymous with Vespertilio formosus, which see further on, it is the same as the Kerivoula formosa of Gray.
