In the other specimen, already designated No. 3, from which the cer- 

 vical vertebrae have been described, a femur is preserved. This is a robust 

 bone, with shaft flattened behind, and large extremities. The fossa liga- 

 menti-teris is large. The great trochanter does not extend beyond the head, 

 and the exterior edge is thick and strongly recurved, inclosing a small 

 transversely deep trochanteric fossa. The little trochanter is a prominent 

 acute convex edge. The rotular groove is moderately wide and moderately 

 prominent. Its lateral ridges are equal. The femoral condyles are sub- 

 equal and stand well apart. Their surface is not cut off by notches from 



the rotular.

Sj^ecimen No. 4 exhibits a perfectly preserved third trochanter, which 

 is broken in Nos. 1 and 3. It has one concave side and a truncate extrem- 

 ity slightly recurved to the concave side. 



In Nos. 1 and 3, tibiae which have lost their epiphyses are preserved. 

 The crest is prominent, and continues to below the middle of the shaft. At 

 the latter point it disjjlays the peculiarity of becoming more prominent than 

 above it, and is acute and recurved outwards, as is sometimes seen in the 

 extremity of the bicipital crest of the humerus. Just below it the section
