sharp at the end, and with bodies of much larger diameter — from 

 10 to 12 inchea. Then follows a strong vertebra, the thirteenth, 

 12 inches in diameter, with a smaller and shorter transverse process, 

 which seems to me the first caudal ; but as the epiphysis is wanting, 

 there is no attachment for the hsemapophysis on its hinder end. In- 

 deed its body is flattened on the under side, not cariaated as the body 

 of the antecedent ; which also seems to me to prove that it is the 

 first caudal. Of heemapophyses we have four ia the Museum, of 

 unequal size, the first 5 inches high, the largest 8 inches, and 3 to 

 4 inches broad between the laminae.

 or eight are preserved. I send you drawings of the upper and lower 

 extremities of the first four (figs. 81-84).

" The sternum is wanting ; and of the os hyoideum we have only 

 the corpus, of precisely the same form as that figured in Cuvier's 

 Oss. Foss. pi. 25. f. 14.
