The line on the anterior side of the anterior feet, near the wrist, is wanting in a second specimen. This species varies very much in size; another specimen measured-- ft. in. In total length (excepting the hair at tip of tail) 3 2-1/2 Tail (excepting the hair at tip of tail) 0 11-3/4 Ear from top of head to tip 0 3-5/8 The snout was narrower than in the preceding specimens, but in colour similar. Another specimen was destitute of the cinnamon colour, excepting on the snout, where it was but slightly apparent; the general colour was, therefore, gray with an intermixture of black, in remote spots and lines, varying in position and figure with the direction of the hair. 2. _Canis nubilus._--Dusky, the hair cinereous at base, then brownish-black, then gray, then black; the proportion of black upon the hair is so considerable as to give to the whole animal a much darker colour than the darkest of the _latrans_; but the gray of the hairs combining with the black tips, in the general effect, produce a mottled appearance; the gray colour, predominates on the lower part of the sides; _ears_ short, deep brownish-black, with a patch of gray hair on the anterior side within; _muzzle_ blackish above; _superior lips_, anterior to the canine teeth, gray; _inferior jaw_ at tip, and extending in a narrowed line backwards, nearly to the origin of the neck, gray; _beneath_ dusky ferruginous, greyish, with long hair between the hind thighs, and with a large white spot on the breast; the ferruginous colour is very much narrowed on the neck, but is dilated on the lower part of the cheeks; _legs_ brownish-black, with but a slight admixture of gray hairs, excepting on the anterior edge of the hind thighs, and the lower edgings of the toes, where the gray predominates; the _tail_ is short, fusiform, a little tinged with ferruginous black above, near the base and at tip, the tip of the trunk hardly attaining to the os calcis; the longer hairs of the back, particularly over the shoulders, resemble a short sparse mane. ft. in.
