Family RHAMPHORHYNCHID^E. 



Tail (at least usually) long ; skull less bird-like than in the 

 Pterodactylidce, and often comparatively short and stout ; jaws not 

 always toothed to their anterior extremity ; nares frequently small 

 and separated by a complete bar from the preorbital vacuity ; meta- 

 carpus much shorter than half the length of the ulna ; proximal half 

 of tarsus sometimes anchylosed to tibia. 



Genus SCAPHOGNATHUS, Wagner l . 



Syn. Pachyrhamphus, Fitzinger 2 . 

 Brachytrachelus, Giebel 3 . 



In the type species, skull massive, without a distinct rostrum ; 

 nares small, and separated by a broad bar from preorbital vacuity ; 

 teeth subequal, nearly vertical, and extending anteriorly to the 

 extremities of the jaws, and backwards to the hinder part of the 

 preorbital vacuity ; alveolar border of jaws and inferior border of 

 mandible nearly straight ; neck short and thick ; tail unknown ; 

 other characters as in Rhamphorliynchus. Zittel 4 would include 

 both this genus and Omithochirus in the latter.
