The pelvis lias a large transverse expansion. The iliac plates are ovoid 

 in outline, with the apex outwards and downwards. The margins are 

 rather thin excei)ting' the internal above the acetabulum. These are 

 massive, and with a longitudinal excavation. They terminate in a deep 

 oblique excavation for tlie diapo[)hy.ses of the sacrum. The inferior 

 margin rises com])ressed from Just above the acetabulum. The hitter is 

 large lor the size of the ilia, and its margins rise to a slight elevation 

 beneath the exterior margins of the latter. The incisura acetahuli is ob- 

 clavate, and nearly symmetrical. The as Isehuim. is compressed and 

 deeper than the pubis. It possesses a tuberosity on the posterior in- 

 ferior margin. The ohturator foramen is small, and is a vertical oval. 

 The ^jf?>t.s' is rather slender and short. Its section at base is subtri^n- 

 guhir; beyond, it becomes more compressed, and is si>irally twisted on 

 itself through a part of a circle. Its anterior margin near the symphy- 

 sis, is strongly rugose for the origin of the peciineus muscle ; the rugosity 

 extends into a band on the outside of its proximal portion.

The general character of the pelvis is more like that of the elephant 

 than that of any Perih^sodactyle. It agrees with the former and differs 

 from that of the rhinocerus in the shortness of the pedestals of the ilias 

 or rather in the sessile position of the latter on the acetabula; also in 

 the absence of production of the iliac crests in advance of and above 

 the sacrum. It is also elephantine in the shortness of the inferior ele- 

 ments of the pelvis. 



Of vertebra^ there are preserved a dorsal, two lumbar, and some 

 sacral. The lirst is very short and transverse. It is so injured that I can 

 only give measurements. The base of the transverse neurapophysis is 

 a llat oval ; both cai)itular articular surfaces are deep. The anterior 

 lumbar is longer, but still short; itsarticular faces are slightly concave. 

 The neural arch is wide, and su[tports the dia.pophyses. The sides of 

 the centium are concave and pierced by foramina, and there is a strong 

 rugose hyi)aitopliyseal keel. The section at the middle is subtriangular. 

 I have thie(^ sacral vertebrae which are separated by very distinct sutures. 

 Tliey diminish very rapidly in size, and the centra become flattened 

 transverse. It is doubtful whether there was a fourth vertebra, and
