The larger part of the pelvis is preserved. It agrees with that of H. 

 speciosum and differs from that of the horse in the subcylindric pubes, but 

 it differs from that of the former in having the peduncles of the ilium flat- 

 ter or deeper fore and aft. The peduncles of the ischium are robust, and 

 are concave on the outer and convex on tlie inner side, less convex, how- 

 ever, than in the horse. The obturator foramen is a more elongate oval.

Both /e?n(?ra are preserved. They display the usual equine characters 

 of long great trochanter and large third trochanter, which is half opposite 

 the inferior half of the prominent keel-shaped small trochanter. The 

 shaft is robust, rather compressed and slightly curved fore and aft. Its 

 section at the middle is an anteroposterior oval. The internal crest of the 

 rotular groove is higher thau the external posteriorly, and projects as well 

 a little inwards ; it is not, however, developed to anything like the extent 

 seen in the horse. The rotular groove is rather wide and is cut off from 

 the external condyle only by a fossa. The intercondylar fossa is rather 

 wide. The supracondylar fossa is large and of subcircular form ; it marks 

 one-third the distance between the condyle and the third trochanter.
