1878.] 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 XX.). 



8. Notes on the Visceral Anatomy 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 dis- 

 secting 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 am aware. The fol- 

 lowing 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. 



On the tongue the filiform papillae are all small ; and among them 

 small papillae fungiformes are sparsely scattered. Three circumval- 

 late 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 sub- 

 lingual) 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 9 1 



Caecum 7 



Large intestine 1 3
