As no complete pelvis of a Coryphodon has been hitherto procured, I 

 describe the present specimen in detail. Its expanded ilia present the un- 

 gulate type, and the wide peduncles resemble those of the elephant. The 

 plate is, however, not so expanded anteroposteriorly as in the genus Elephas, 

 and the crest is more convex. If the crest of the ilium of the camel were 

 considerably more convex, the bone would resemble that of this species of 

 BatJimoclon. It is less dilated anteroposteriorly than in Bhinocerus sp., and 

 has a stouter peduncle than in that genus, Eqims, Tapirus, or Sus. The 

 symphysis is shorter than in any of the genera above mentioned. This is 

 partly due to the fact that the posterior parts of the ischia are not so wide 

 anteroposteriorly as in any of them, the nearest approach being seen in 

 Bhinocerus. The obturator foramen is larger than in any of these genera, 

 excepting Bhinocerus, and there is no tuher ischii at all comparable to what 

 is seen in all those genera. The pubes are slender, and are not so trans- 

 verse as in those genera, but slope posteriorly. The notch of the acetab- 

 ulum is opposite the shaft of the ischium, and not opposite the obturator 

 foramen, as in all the genera named. The sacral articulation is rather 

 long and mai'ks a bevel of the edge of the plate of the ihum.
