 The pelvis differs from that of Circus in being relatively wider, 

 with a shorter and broader antitroehanter, above which is a distinct 

 notch ; and also by the shorter reflected portion of the post-aceta- 

 bular region of the ilium. The humerus and tarso-metatarsus are 

 shorter and stouter.

 part of a recent skeleton, and exhibits the characteristic 

 features in the region of the acetabulum.
