carpal, most of the 4th metacarpal, and the phalanges of the 4th 

 and 5th digits. 



The 1st metacarpal is in general shape much like that of Masso- 

 spondylus, but differs in that its proximal outer corner ends in a 

 point. In this it also differs from Gryponyx. The 1st phalanx 

 differs from that of Massospondylus harn'csi in being relatively 

 longer and more slender. 



The 2nd digit is relatively more slender than in Massospondylus 

 harricsi, and the claw is unlike that of either Massospondylus or 

 Gryponyx, about the same length as the penultimate phalanx. The 

 claw is further remarkable from the fact that the vascular grooves 

 meet each other on the upper side near the union of the middle and 

 distal third, leaving the upper part of the claw separated from the 

 lower, something like the horn of a hornbill. 



The 3rd digit is a little shorter than the 2nd, and the phalanges 

 are narrow and slender. 



The 5th metacarpal is not unlike that of Massospondylus harriesi,. 

 but considerably smaller. 



The following are the principal measurements of the bones of the 



man us :

The right hind foot is nearly complete, but the metatarsals have 

 been broken across the middle, and the 4th is very badly 

 crushed.
