Laurence M. Huey (1942) gave the above names to the jays of this species found in the central portion of the peninsula of Baja California. In his description of it, he says that it “is closest to A. c. hypoleuca of the Cape District of Lower California. From that form it differs in the general tone of the back, which is darker, more slaty; also the underparts are not as white as are those of hypoleuca, having a faint wash of gray color which is more highly exemplified in Aphelocoma californica [=coerulescens] obscura from the northernmost part of the peninsula and in the races farther north in upper California. The bib, or throat, and sides of neck are of a darker shade on both their blue and dusky aspects than are those of hypoleuca, and lighter than those of obscura.”

Of its range, he says: “From near latitude 29° 20', south over the width of the peninsula to the vicinity of Mulejé, on the gulf coast near latitude 27°. On the Pacific slope the range extends farther south, latitude 25° 40’ being reached before intergradation takes place.”

This subspecies seems to be strictly intermediate in characters between the race to the northward of it and that to the southward of it, which might be expected in the intermediate territory that it occupies.
