The coracoid is rather more transversely expanded than in , 

 G. velox, with the posterior border more convex. There is no 

 emargination whatever. The scapula is not unlike that of 

 C. velox. The humerus differs slightly only in that the radial 

 border is more nearly the length of the ulnar, and that the 

 distal facets for the radius and ulna are more obliquely placed 

 to each other. The radius is very distinctly different in the 

 much shorter free outer border, which is shorter than the 

 articular surface of the proximal articular surface. The articu- 

 lation for the radius is placed less obliquely to the long axis 

 and more nearly at right angles to the outer cartilaginous border, 

 which is here less convex and more nearly parallel to the long 

 axis of the bone. The ulna shows only slight differences ; on 

 the outer side of the distal articular surface there is a distinct 

 facet for the medial carpal, wanting in C. velox. 



Of the carpals, the radial is broader on its outer side, remov- 

 ing the first metacarpal further from the radius. Its proximal 

 inner angle is not at all emarginate to help form the free border 

 between the radius and ulna. The medial is rather broader 

 from side to side, the free border more concave and extending 

 from the radius to the ulna ; on the inner side the bone articu- 

 lates for a short distance with the ulna, which is not at all the 

 case in C. velox. The ulnare and the bones of the distal row 

 resemble those of C. velox closely. Of the metacarpals the 

 fourth is peculiar in having the proximal inner angle much 

 produced, so that the proximal articular surface is sinuous, and 

 very oblique to the long axis of the bone.
