Cycnorhamphus suevicus (Quenstedt 1 ). 

 Syn. Pterodactylus suevicus, Quenstedt 2 . 



Pterodactylus wurtembergicus, Quenstedt 3 . 

 Pterodactylus eurychirus, Wagner 4 . 

 Ornithocephalus eurychirus, Wagner 5 . 



This is the only known species of the genus, and is of compara- 

 tively large size ; the length of the cranium being 0,158. 

 Bab. Europe (Germany). 



37370 x. Cast of a slab of lithographic limestone, showing the 

 nearly entire skeleton. The original was obtained from 

 the Kimeridgian of Nurplingen, Wiirtemberg ; and is the 

 type of the species ; it is described and figured by Quenstedt 

 in the memoir cited. Purchased, 1863. 



Family Uncertain. 



Tail apparently long ; jaws toothed to their anterior extremity ; 

 relative lengths of metacarpus and ulna unknown ; skull long or 

 short ; astragalus, at least in some instances, united to tibia. 



It is uncertain whether the members of this group should be 

 included in the JRhamphorhynchidce, or should form a distinct 

 family. 



Genus ORNITHOCHIRUS, Seeley 6 . 



Including Palcsornis, Mantell 7 , Cimoliornis, Owen 8 , Coloborhynchus, 

 Owen 9 , Criorhynchus, Owen 10 , Doratorhynchus, Seeley ll , Cretornis, 

 Fritsch 12 . 



All the species are known by such fragmentary remains that no 

 accurate diagnosis can be given. In the upper jaw the anterior 

 teeth frequently curve in advance of the muzzle ; the teeth may be 

 rounded or compressed, and are frequently inclined forwards ; there
