Show 1876.] MR. A. H. GARROD ON LYCAON PICTUS. 373 The cub (the sex of which was not noted) is of a glossy black all over the back part of the body, inclining to brown on the nose, throat, and chest. The parts under the belly, especially between the hind legs, are of a light brown ; and there is a yellow patch behind the fore limb. The differences in colour, of which it is almost impossible to give an intelligible description on paper only, are extremely well illustrated in the accompanying figures (Plate X X . ). 8. Notes on the Visceral A n a t o m y of Lycaon pictus, and of Nyctereutes procyonides. By A. H. GARROD, M.A., F.R.S. [Received March 18, 1878.] Having had the opportunity in my prosectorial capacity of dissecting a male specimen of Lycaon pictus, as well as several, both male and female, of Nyctereutes procyonides, I take the present opportunity of giving the results at which I have arrived. Lycaon pictus.-This canine animal, so different from its allies in its digitation, is not at all aberrant in its visceral anatomy, which has not been previously described, so far as I a m aware. The following are some of the most important details :- The anterior portion of the palate is black, the pigment extending back as far as half an inch, onto the soft palate, of which the posterior one and a half inch is unpigmented. There is no uvula, a median shallow notch occupying its position. The tonsils are elongate, lunate, and vertical in position. O n the tongue the filiform papillae are all small; arrtl among them small papillae fungiformes are sparsely scattered. Three circumvallate papillae on each side, increasing in size from before backwards, and converging posteriorly, form the normal V . There is no trace of a lytta. Of the salivary glands the compact submaxillaries are slightly larger than the irregularly shaped parotids. The zygomatic glands are as big as small chestnuts. The accessory submaxillary (or sublingual) glands are situated nearly in contact, in the middle line of the floor of the mouth. The thyroid gland is formed of two parts, each of the size of a sheep's kidney, these being joined at the inferior internal angle by a narrow isthmus of thyroid tissue. The superior thyroid artery is enormous. The stomach presented no differences from that of Canis famili-aris. The following are the lengths of the intestines :- Small intestine Caecum ......
