lines below the suckers (the proliferating area), is 3 millimetres. 

 The breadth of the largest of the proglottides is 3"1 centimetres, 

 their depth being 4 '5 millimetres. One decimetre from tiie end of 

 the scolex the proglottides are 1*42 centimetre in breadth. 



In one respect the scolex differs from that described by Dr. Peters, 

 the rostellum or little conical elevation between the suckers being 

 scarcely even indicated as such. This, however, seems hardly suffi- 

 cient to justify specific separation. 



It is an interesting fact that three different species oi Rhinoceros, 

 so separated in their distribution, should be troubled with the same 

 tapeworm, which must therefore, unvarying, have followed the an- 

 cestral species in its different variations, now so easily distinguishable. 



6. Notes on the Anatomy of the Chinese Water-Deer 

 [Hydropotes inermis). By A. H. Garrod, M.A.^ F.R.S., 

 Prosector to the Society. 



[Eeceived October 1, 1877.] 



Since the discovery by Mr. Swinhoe of the Chinese Water-Deer, 

 which in the ' Proceedings ' of this Society ^ he named Hydropotes 

 inermis, naturalists have been anxious to obtain information upon its 

 visceral anatomy, together with other features not ascertainable from 

 adult skins or from the skeleton. At Tours our Corresponding 

 Member M. J. Comely has succeeded in breeding the species-, the 

 Society having allowed him the loan of its male specimen, and his 

 example being of the opposite sex. One of the three young ones, a 

 female, having died shortly after its birth, M. Comely forwarded it 

 to Mr. Sclater, who has kindly placed it in my hands for description ; 

 and it is my notes upon this specimen which I take an opportunity 

 of laying before the Society. 



From the tip of the nose to the base of the tail the specimen is 

 16 inches, the tail being an inch long. From the top of the 

 shoulder to the tip of the hoof of the fore limb it measures 12 inches. 

 The colour of the hair, after being in spirit for some days and 

 then dried, is a dark greyish brown, which is redder along the back 

 than at the sides. The abdomen, as well as the throat, is a dirty 

 white, as are the hairy inner surfaces of the ears. 



The fawn is spotted with white ^. The spots are not numerous or 

 pronounced. They run in longitudinal lines from the neck to the 

 tail, with a median area about 1*5 inch broad unspotted. There 

 is one line, the upper, fairly defined and uninterrupted ; two others, 

 lower down, are irregular and shorter. The spots are not distinct,

^ In the Society's ' Proceedings,' 1872, p. 817, Mr. Swinhoe remarks, " I 

 learn from Mr. Eussell that the fawn is spotted with dark-brown spota all over 

 the hind quartei's." I could not deiect any trace of these.
