Carpals. — There can be little question as to the correctness of 

 the association of these bones since they were found close together, 

 and near by was a long series of Diplodocus caudals. Beneath 

 the radius was found a large flattened carpal which from its con- 

 nection with both radius and ulna is believed to represent a 

 conjoined radiale and intermedium or scapho-lunar bone ; this 

 bone is much thicker behind than in front ; it has a large radial 

 facet, slightly concave, and a smaller oblique ulnar facet ; inferi- 

 orly there is a single convexity with ill-defined areas for the car- 

 tilaginous trapezium, trapezoid and magnum ; the cuneiform in 

 this specimen is crushed beyond recognition ; there is a small 

 ossicle which may represent the unciform or one of the other 

 carpalia of the second row. 



Fore Limb of Diplodocus, No. 380. 



This generic reference is somewhat uncertain. The associated 

 parts, consisting of radius, ulna, supposed scapho-lunar, cunei- 

 form and two ossicles probably belong to a young Diplodocus. 

 This limb is important, because it includes the terminal phalan- 

 ges. The position of the latter, however, was not positively 

 determined.

The right and left man us found with these limbs have already 

 been described by Osborn (/. c, p. 168) ; the elements were found 

 in position and therefore yield important information, although 

 the limb bones are much crushed. As in Diplodocus, the radius
