CLASSIFICATION OF THE CERVID^. 



915 



Since my description of the species, the Society has received two 

 living specimens ( d and $ ) from Mr. Robertson, to whom I was in- 

 debted for my original knowledge of its existence. Cervus mesopo- 

 tamicus is a very much larger animal than C. dama. 



B. Distal ends of metacarpi remaining. (Telemetacarpi.) 



Posterior portion of the narial cavity not divided by the vomer 



into two distinct chambers. 

 Tuft of hair on the external surface of the metatarsus when 

 present above the centre of that bone. Tuft on inside of the 

 tarsus absent. 



4. Alces. 



1827. Alces (subgen.), Ham. Sm., Griff. An. Kingd. vol. v. p. 303. 



Antlers dichotomous, both main branches palmated, the posterior 



branch (fig. 11,6) much surpassing the anterior branch (fig. 1 1, a) in 



dimensions. Anterior nares of great extent, owing to the shortness 



of the nasals. Lacrymal pit and anteorbital vacuity moderate. 



Fig. 11. 



Alces machlis. 



Ascending rami of the praemaxiliEe long, not articulating with the 

 nasals. Incisors decreasing gradually in size from the central to the 

 external pair. 



A very small triangular rhinarium. Head very long, neck and 

 body short, legs very long, stature great. Young unspotted. 



Distribution. North Palaearctic and Nearctic regions.
