slender, decidedly exceeding in length the outer pair, Mtc. I and 

 Mtc. V. The doubt expressed in the earlier description of 

 this manus as to the presence of terminal phalanges and a claw 

 upon the first digit still remains ; the proximal phalanx asso- 

 ciated with Mtc. I indicates that the terminal phalanx was 

 missing.

These are especially interesting and valuable because of the 

 absence of crushing, which gives the rounded or radial dispos- 

 ition of these bones as seen from above and in front (Fig. 5).

The lateral metacarpals, I, V, have a more flattened section, the 

 median metacarpals II, III, IV, present a more rounded section. 

 Portions of the proximal and distal facets are well illustrated in 

 the figure. As in Diplodocus the proximal facets decrease stead- 

 ily in antero-posterior diameter as we pass from I to V. The 

 posterior faces exhibit rugose areas for retractor tendons.
