582 GEOLOGICAL SURVEY OF THE TERRITORIES. 



These remains, which were not found in association with a cranium, 

 consist of several vertebrae, some carpal bones, and the entire hind limb 

 of the left side except the toes and the cuneiform and navicular bones. 



The odontoid process is very stout, with a descending trihedral apex. 

 Length M. .078; diameter at base, .048. A dorsal vertebra, with a single 

 (anterior) (;apitular articular face, is quite concave in front.

A cervical vertebra has the proportions of the dorsal as to its cent- 

 rum, thus difleriug materially from species previously described. The 

 articular surfaces are slightly concave.

The femur resembles that of the other species already described, but 

 is remarkable for the relatively small size of the head. While the 

 lengths of the bone are not very diiierent, and the expanse of the great 

 trochanter about the same, the head of L. cornutws is large, the present 

 one is very much smaller, and that of JE. "pressicornis intermediate. 

 There is a rudimental third trochanter, and the condyles are as large 

 as, and similar to, those of E. press icornis. The external marginal con- 

 dylar ridge is quite short. The shaft is broken and some small pieces 

 lost ; it is now 26 inches long, but was no doubt longer when complete.

The tihia is perfectly preserved. It is short and stout, and with mass- 

 ive extremities. The outer basal part of the spine remains and is 

 prominent. The cotyli are not oblique ; the inner is sub-round, the outer 

 transverse, widening outwardly ; their long axes are at right angles to 

 each other. The crest is a low ridge of contact of the cotyli. The 

 superior fibular face is a transverse oval ; the inferior much smaller than 

 in U. pressicornis. The shaft is contracted, and flattened behind and on 

 the inner side. The distal extremity is transverse, less truncated for 

 the fibula than in E. pressicornis^ less convex behind, and with a less 

 prominent external malleolus. The jjoint dividing the astragalus be- 

 hind is more prominent.
