of Axis and Cervus will depend vipon the views of each individual 

 taxonomist. The point I wish to emphasise is that the characters 

 on which they were established have not, in my opinion, so high 

 a systematic value as those to which full generic imporbmce is 

 here attached. I do not, for example, think that in the future 

 J)ama will be set down as a subgenus of Cervas, whatever coui-.se 

 niay be adopted with regard to Eucervus, Panolia, or Pseudcixis. 



a. DUtal portion of lateral metacarpals persistent, interungual 



iutegiiment, where known, tliickly hairy. {Telemetacarpalia.) . Capkeolin^b 

 b. Naviculo-cuboid and external cuneiform boues of tarsus united ; 



no pc'dal, tarsal or metatarsal glands Fudu. 



b'. Naviculo-cuhoid and external cuueiibrm bones of tarsus 

 separated ; pedal glands present at least on the hind feet 

 (? in ISucet'vtcs, Blastocerus, Hippocamelns) ; tar^jal or meta- 

 tarsal gland, sometiujes both, present, 

 c. Vomer dividing the posterior narial apevture, 

 d. Ithinarium large ; hoofs narrower, tied together posteriorly 

 or througiiout their posterior half ; pasterns not depresstxl 

 behind. 



e. Metatai-sal gland very long Eucervus. 



c'. Metatarsal gland normal or absent. 

 y. Metatarsal gland present ; a large pocket-like pedal 



gland on the front as well as on the hind foot Dorcelajthus. 



f. Metatarsal gland absent; at most a small glandular 

 pocket on the front feet (? in Blastocefus and Hip- 

 pocamehis). 

 g. I'reorbital glands moderately large ; antlers branched . 



Blastocerus, Hippocamel u, 



ff'. Preorbital glands small ; antlers unbranched Mazama. 



d\ No rhinarium, muzzle hairj' ; hoofs broad, widely sc])a- 

 rableat the heels, owing to the anterior jjosition of the 

 web ; pedal glands on the hind feet only, and consisting, 

 as ill 3fazaMa,Dorcelaphu,s, And Capreolus, of a deep 

 pocket opening high up the pastern ; tarsal and preorbital 



glands large Raitji/cr. 



c'. Vomer not dividing the posterior nares. 



k. Pedal gland either a deep and long inteixligital cleft or 



a large pouch with constricted orifice on the hind foot; 



rhinarium large ; no tarsal gland. 



«. Pedal gland a large pouch, with constricted orifice 



opening high up the pastern ; preorbital gland absent ; 



metatarsal gland prasent Caprenlus. 



i'. Pedal gland a deep interdigital cleft, the hoofs united 

 at the heels by a fold of integument ; preorbital 



gland present ; metatarsal gland absent Hi/dropotes. 



h'. Pedal gland a comparatively small invagination situated 

 as in Capreolus and -Rflrti/j/er; rhiuai-iura very small; 

 tarsal and preorbital glands present ; metatarsal gland 

 small or absent Alee. 



a'. Proximal portion of lateral metacarpals persistent or occasion- 

 ally wanting. (Plesiometacarpalia.) CeevinJi. 



k. Tarsus with naviculo-cuboid and cuneiform bones united; pedal 

 gland a deep cleft on the hind feet; hoofs united only at the 



heels Cer villus, Elaphodiis. 



k'. Tarsus with naviculo-cuboid and cuneiform bones separated. 

 /. Hoofs of hind feet united only at the heels by a close fold of 

 skin ; the gland a long and deep hair-lined interdigital 

 cleft as in Cervulus; a moderately deep cleft also on the 



pastern of the front foot Da ma. 



v. Hoofs of hind feet united almost throughout their iiasal 

 depth by a deep interungual web ; no deep cleft on pastern 

 of front foot. 

 m. Pedal gland a long and moderately deep cleft on the 

 pastern of the hind feet ; metatarsal gland naked, over- 

 lapped by marginal hairs Axis.
