ORXITBOCHIRTTS. 13 



Smaller than the preceding, with the skull not produced into a 

 distinct rostrum, and with the teeth short, rounded, and not pro- 

 jecting in advance of the muzzle ; scapula and coracoid anchylosed. 

 The form of the muzzle approximates to that of Scaphognathus 

 crassirostris, but the teeth do not extend so far back. The calcu- 

 lated length of the cranium on the proportions of that of the latter 

 would be 0,255. 



Hab. Europe (England).
