A number of vertebras are preserved on fragments of a softer rock of 

 darker color than the specimen above described. It is possible that they 

 belong to another species of the genus, as I observe some peculiarity in the 

 caudal vertebra. The base of the neural spine is so robust as to cover the 

 anterior section of the centrum, and does not therefore present the appear- 

 ance of coming off from the posterior section alone, as is the case in the 

 typical specimen. I have, however, not seen the arches of the anterior 

 caudals of the latter. 

 A marked character of the dorsal vertebras, is the appearance of hyperos-
