Fore Limb of Brontosaurus, No. 276. 



In our collection are mounted two fore limbs of Brontosaurus, 

 neither of which is complete. No. 276 is a young Bronto- 

 saurus carpus with which have been associated arbitrarily No. 

 318, ulna and radius, with extensive restoration. The carpals, as 

 compared with those of Diplodocus, Nos. 594, 588, or 380, above 

 described, are shorter and more robust. The manus of No. 268 

 has already been described (Osborn, 1899, p. 171). The meta- 

 carpals attain a very considerable length, but also acquire robust 

 proportions, which enable us to readily distinguish them from 

 those oi Diplodocus J the placing of these elements is, however, 

 somewhat conjectural. With the carpus is found the supposed 

 scapho-lunar and three ossicles, Avhich probably represent the 

 carpals of the second row.
