1877.] THE CHINESE WATER-DEER. 791 



The spleen is circular, flat on its gastric, and convex on its 

 parietal surface. 



The liver (fig. 1, p. 790) has no gall-bladder, therein being quite 

 cervine. There are one or two minor lobules so situated as to develop 

 a spurious cystic fossa ; and what is still further interesting is, that in 

 that fossa there is a white fibrous cord which runs from the transverse 

 fissure nearly to the ventral margin of the abdominal surface of the 

 right lobe, exactly in the situation of a gall-bladder. Once pre- 

 viously in a Deer (Cervus virginianus, I believe) have I seen a 

 similarly situated fibrous cord, which I can hardly believe to be any 

 thing else than an atrophied gall-bladder, although I was not able 

 to trace its connexion with the bile-duct on account of the bad state 

 of preservation of the specimen. 



The Spigelian lobe is proportionally well developed, being tongue - 

 shaped (or rusiform) as in the genus Rusa. The caudate lobe is of 

 fair size. The umbilical fissure is shallow, the left hepatic lobe being 

 slightly smaller than the right, both being of a square shape. 



The intestines measure 9 feet 8 inches, the small intestines 7| feet 

 long, the large 2 feet 2 inches. The caecum is 1^ inch long. No 

 trace is visible of an ileo-csecal gland. There are 2^ colic coils, 

 there being an irregular reversed half-loop in the returning portion 

 of the spiral. 



In the bicorn uterus of this nC'T-born animal the cotyledonary 

 papillae are as manifest as in that of the pregnant adult. There are 

 four in one cornu and three in the other, the highest of these in 

 the latter being particularly large. I have, in my paper on the 

 visceral anatomy of the Ruminantia (P. Z. S. 1877, p. 12), men- 

 tioned that in a pregnant uterus of Hydropotes, which was lent me 

 kindly by Mr. Ewart, of University College, there were three coty- 

 ledons in one cornu and five in the other, which agrees very closely 

 with the specimen under consideration. 



The brain is very much like that of the Pudu Deer (Cervus piidu) 

 figured by Prof. Flower \ mainly differing in that the hippocampal 

 gyrus is much less conspicuous upon the superior aspect. It is 

 considerably more convoluted than that of Moschus moschiferus, 

 upon the typical Huminant pattern. I take the opportunity of 

 figuring it {vide fig. 2, p. 792) from above. 



Reviewing the above-described anatomical features, the differences 

 between the visceral anatomy of Hydropotes inermis and Moschus 

 moschiferus clearly indicate the slightness of their relationship. In 

 the former we find a fairly convoluted brain, a quadruplicate psal- 

 terium with 10 primary laminae, no ileo-caecal gland, no gall- 

 bladder, two and a half colic coils, and an oligocotyledonophorous 

 uterus ; whilst in the latter the brain is comparatively smooth, the 

 psalterium is dupliciplicate, with 20 or so primary laminae, a large 

 ileo-caecal gland, a gall-bladder, three and a half colic coils, and a 

 specialized linear cotyledonary arrangement. In other words, 

 Hydropotes is typically Cervine, whilst Moschus is any thing but so. 



To what group of the Cervidae Hydropotes is most allied there is 

 1 r. Z. S. 1875, p. 177.
