A segment of the sternum is subquadi-ate and flat, as in the C. latidens, 

 but thicker. The length is M. .058; width at middle, .044. 



The femur is rather elongate, with the shaft less robust than in the 

 Bathnodon radians (see Plate XLVII). The head projects beyond the great 

 trochanter, and has a deep fossa Ugamenti teris near the posterior border. 

 The little trochanter is a prominent crest of two inches in length on the 

 internal edge of the bone. The third trochanter is broken off. Its base is 

 at the middle of the shaft. The rotular groove is rather wide, and the lat- 

 eral borders are equal, and not much elongated. It extends well proximally. 

 The epicondyles are insignificant; the external is impressed with three fos- 

 sae, one on the edge of the condyle, and the middle one is the largest. The 

 internal condyle has the widest sweep, and looks obliquely towards the 

 external condyle. The inter-condylar fissure is rather narrow and deep.

The tibia is much shorter than the femur, and is rather more slender 

 than in some species of the genus. It presents the generic characters of 

 flat crest and ungrooved distal articular face. The most slender part of 

 the shaft is below the middle. The inner femoral cotylus has a consider- 

 ably greater anteroposterior diameter, and there is a free edge behind it 

 which increases the projection beyond external cotylus. There are var- 

 ious longitudinal rugosities on the internal face of the proximal third of 

 the bone, and the wide face of the crest is grooved striate. The malleolar 

 process is not large, is acuminate, and turns backwards. The posterior 

 border has an angle near the base of the malleolus, but there is no groove
