THE OSTEOLOGY OF ELOTHERIUM. 277 
The lower milk-premolars are even simpler than the upper; dp 5 and y are com- 
pressed and conical, without accessory cusps, but with serrate edges and sharply-pointed 
summit. Each of these teeth is supported upon two fangs. Dp < is of the usual artio- 
dactyl type, consisting of three transverse pairs of cusps, of which the median pair is the 
largest, and the anterior pair the smallest. A small talon is formed by the elevation of 
the cingulum in the median line, behind the posterior pair of cusps. 
This account of the milk dentition applies only to £. mortoni; I have not seen these 
teeth in the larger species.
