Vertebral Column: The vertebral column is represented by fragments 

 of the cervicals, the centrum of one dorsal, fragments of four lumbars, 

 and the anterior portion of the sacrum. 



From a fragment of the atlas it is evident that this bone was quite 

 elongate and high, and that the base of the transverse process was 

 pierced by a foramen. The centra of the anterior cervicals have a 

 sharp ventral keel, which terminates posteriorly in an enlarged rounded 

 tubercle, while two posterior cervicals (the fifth and sixth?), have 

 heavy and quite high neural spines. 



The centra of the lumbar vertebrae are heavy, broad, and depressed, 

 especially those in the posterior region; they have a sharper ventral 

 keel and are much less opisthoccelous than in the recent tapir, but 

 the posterior face of the transverse process of the last lumbar is pro- 

 vided with a large articular face, which meets a corresponding face on 

 the anterior extremity of the pleurapophysis of the first sacral vertebra 

 as in the recent genus. 



The centra of the sacrum decrease rapidly in their vertical dimen- 

 sion from before backward while transversely they appear to maintain 

 a greater uniformity, which is again a tapiroid character. The pleur- 

 apophysis of the first sacral only supported the ilium, while in the 

 tapir the second also takes a considerable part in this function. 



Limbs: The fore and hind limbs are represented by numerous frag- 

 ments. The glenoid cavity of the scapula is quite concave and 

 presents a prominent descending process on its anterior margin. 

 The coracoid process is very prominent and occupies a position slightly 

 separated from the glenoid cavity, similar to that in the tapir, while 

 the spine, judging from the fragment with which we are dealing, 

 formed a more prominent median ridge on the neck and possibly rises 

 more rapidly and nearer the glenoid cavity than in the recent genus. 



The inter-trochlear ridge of the distal articulation of the humerus 

 is shifted well over to the ulnar side and is prominently developed, 

 as in the tapir. The entepicondyle is also similarly developed, but 

 the supinator ridge is proportionally somewhat less prominent.
