of a peculiar genus — the Dermodactylus montanns. In the Cretaceous, 

 the representatives of a group distinguished by its toothless jaws are 

 abundant, and of such two si)ecies are described. In this paper two 

 are described — '■'•Pteranodon nanus,''^ and '■^Nyctodactylus gracilis.^'' The 

 large Pteranodon first described exhibited a noteworthy peculiarity of 

 its skeleton. " To aid the powerful wings in flight, the pectoral arch 

 is strengthened (1) by the anchylosis of several vertebrae; (2) by the 

 robust scapulae articulating on oppo^iite sides of the common neural 

 spine of these vertebrae. This is virtually a repetition of the pelvic 

 arch on a much larger scale." This structure was apparently not mani- 

 fested in NyctodactyUis (A. J. S. (3), xxi, 342-343.)
