HYRACHYUS. 669 



more than twice as long as the crest, and is gently concave. The crest 



truncates this and the inferior border of the ilium at right angles. The 



crest expands very slightly distally forward and downward. The ischio- 



pubic suture is a long one, and the obturator foramen a long oval ; the 



inferior pelvic elements do not form a transverse, but meet at an open 



angle.

Femur. — The head projects inward on a well-marked neck. The great 

 trochanter is strongly recurved and presents an anterior tuberosity as 

 well It rises to an incurved apex much elevated above the head. The 

 prominence of the front of the femur is continued into the front of the 

 trochanter. The outer margin of the shaft is thin, and at a point two- 

 fifths the length from the proximal end is produced into a low third 

 trochanter, which is curved forward and thickened on the margin. The 

 trochlea is well elevated, the inner margin a little the more so, and is 

 narrow. It is continuous with the surface of the inner condyle, which is 

 the shorter and more vertical ; the external is longer and divergent ; its 

 terminal face is marked by two fossae, one in front of the other just out- 

 side the distal end of the ridge bordering the trochlea. Little trochanter 



moderate.

The tibia has a broad prominent crest, which is remarkable in being 

 deeply fissured longitudinally at its superior portion. The tendinous notch 

 separates the outer portion of the crest from the spreading margin of the 

 outer cotyloid face. The crest disappears at the proximal third, and the
