MR. R. I. POCOCK ON THE EXTERNAL 



Genus Hydropotes Swinh. 

 Hydropotes inermis Swinh. (p. 956). 



Some of the external characters and the visceral anatomy of 

 this aberrant genus were described by Garrod (P. Z. S.^ 1877, 

 pp. 789-792). Additional information was later supplied by 

 Forbes (P. Z. S. 1882, p. 637). 



The head is remarkable for the complete absence of all trace of 

 antlers — a feature in which this genus is unique in the Cervidse,- — • 

 the long, slightly curved, pointed and movable upper canines, and 

 the narrow muzzle. (Text-fig. 7.) 



The lightly areolated rMnarium has a deep wide infranarial 

 portion, which is wider than the supranarial portion and therefore 

 much wider than the internarial area. The latter is of normal

width. The supranarial portion is unusually high, so that the 

 height of the entire rhinarium, as described by Garrod, is about 

 equal to its width. (Text-iig. 8, C.) 



The mystacial vihrissce are tolerably numerous and of average 

 leno-th. The superciliaries and infraorbitals are also normally 

 developed ; but in the thick hairs of the cheek and throat I can 

 find no trace of genal or interraaial vibrissse, which are some- 

 times present but never abundant in other Cervidse. 



The preorhital gland is represented by a small shallow pouch 

 lodged in a naked area of skin just in front of the eye. (Text- 

 figs! 7 ; 8, D.^ • . . 



The ear is short and broad, and densely clothed withm with 

 hairs, which meet in the middle line of the hollow of the pinna.
