Subfamily TeleosaurinjE. 



Skull either moderately or excessively elongated, with the teeth 

 moderately or very slender, and orbits regular and directed more 

 or less frontally, so as to be completely visible from the frontal 

 aspect. Anterior nares transversely elongated, and directed more 

 or less anteriorly ; nasals separated by a long interval from the pre- 

 maxillee ; premaxillse usually short and more or less expanded, and 

 generally with four dental alveoli. The palatal aspect of the max- 

 illae and mandible somewhat convex. Nasals small; lachrymals 

 large ; frontals and prefrontals small ; palato-pterygoid vacuities not 

 extensive. 



The terms Teleidosaurus, Pelagosaurus, and Steneosaurus were 

 originally employed by Deslongchamps as subgenera of Teleosaurus, 

 but were subsequently raised to the rank of genera.
