The teeth (^| in number) are confined to the anterior part of 

 the jaws, and are small, conical, curved, and sharp- pointed when 

 unworn. The cranium is broad and depressed, and the rostral not 

 longer than the cranial portion ; the upper surf ace of the cranium is 

 broad and flat. The centra of the anterior five or six cervical ver-

 caudal vertebra is about equal to their width.

 whereas they really accord in this respect with Globicephalus.
