442 ON LYCAON PICTUS 
73. NOTES ON THE VISCERAL ANATOMY OF LYCAON 
PICTUS AND OF NYCTEREUTES PROCYONIDES* 
Havine 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. 
Iyecaon 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 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, on to 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 papille are all small ; and among them 
small papille fungiformes are sparsely scattered. The circumvallate 
papille 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 familiaris. 
The following are the lengths of the intestines :—
