374 MR. A. H. GARROD ON LYCAON PICTUS. [Mftr. 19, 



The caecum is quite caniform, its curves being exactly represented 

 in that of Canis familiaris 1 . 



The liver is deeply fissured, upon the same plan as in all the Canidae 

 — and all the Carnivora, in fact, — the cystic fissure being very deep, 

 which allows the fundus of the gall-bladder to appear on the 

 diaphragmatic surface of the organ. The left lateral lobe is the 

 largest, the right central and right lateral being slightly smaller. 

 These last are half as large again as the caudate and left central, 

 which are at least four times the bulk of the Spigelian, upon which 

 latter there is a small accessory lobule. 



In the generative organs, as in all Canidae, the prostate is large, 

 whilst Cowper's glands and the vesiculae seminales are absent. The 

 os penis is large, quite straight, four inches in length, and deeply 

 grooved, as in all the Canidae, along its lower surface. 



In the lungs there are three lobes to the left, and four to the 

 right, one of the latter being azygos. The median lobes of both 

 sides are the smallest ; the inferior the largest. The fissures between 

 the lobes are all deep. 



The brain of Lycaon pictus is perfectly dog-like, resembling that 

 of Canis lupus (as figured by Leuret and Gratiolet 2 ) in almost every 

 detail, the division of the posterior limb of the gyrus third above 

 the Sylvian fissure extending as far forward on the superior cerebral 

 surface as in that species, or even further, the anterior superior angle 

 of the gyrus next below it being rather more strongly developed. 

 The sulcus between the uppermost (or fourth) gyrus and the 

 third is parallel to the great longitudinal fissure between the hemi- 

 spheres. 



In Nyctereutes procyonides the tongue is covered with filiform 

 papillae smaller in size than in Lycaon pictus, allowing the pro- 

 portionally larger fungiform papillae to appear more conspicuously 

 among them. These latter posteriorly become the papillae circum- 

 vallatae, five on each side, larger posteriorly, and arranged in a V- 

 manner. 



There is no uvula ; and the soft palate embraces the upper end 

 of the larynx with facility. 



The stomach is not peculiar, except that it is more than usually 

 muscular at its pyloric end. 



In an adult male which died on the 2nd of February last, the 

 father of a litter of six born on May 2nd 1877, the small intestine 

 measured eight feet ; the large, one foot and an inch, the caecum 

 being two inches long, rounded at the end, and slightly turned to the 

 left side apically. It is figured in the accompanying sketch. 



In three other specimens, not adult, the following were the 

 intestinal lengths : —
