The Dusky Wolf differs little from the pure black variety which follows. It was
considered by Mr. Say to be a distinct species, on account of its colour, a different
physiognomy from that of the Common Red Wolf, its more robust form, and its
shorter ears; but, with the exception of colour, these characters are common to all
the varieties of the northern American Wolf, and are in fact some of the peculiarities
that distinguish them from Pyrenean wolves.

Mr. Say’s specimen had “ a dusky colour; the hair cinereous at the base, then brownish-
black, then gray, then black; the gray of the hairs combining with the black tips to produce
a mottled appearance; the gray predominating on the sides. Ears short, deep brownish-
black, with a patch of gray hair within. The under parts dusky ferruginous, grayish with
long hairs between the thighs, and with a large white spot on the breast; the ferruginous
colour very much narrowed on the neck, but dilated on the lower part of the cheeks;
legs brownish-black, with 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 predominated ; the tail was
short, fusiform, a little tinged with ferruginous, black above, near the base, and at the tip ;
the top of the trunk hardly attaining to the os calcis ; the longer hairs of the back, particularly
over the shoulders, resembled a short, sparse mane.”

Society.
