1. COBLENZIAN FoSSILS FROM LyNTON. 

 (PLATE XVII.) 



THE specimens described below were collected by my friend 

 Mr. J. G. Hamling, F.G.S., and kindly placed by him in my 

 hands for description. Being casts and often much obscured by 

 injury and distortion, their identification must be in a degree 

 problematical, but for the most part they seem to agree with 

 German species of the Upper Coblenzien age. 



Bellerophon, sp. 



A slab with several poor casts comes from the " Clifif path, W. of 

 Woodabay." They appear high with rounded back.

 margin. Front wing large, rounded, not truncated in front. Hind 

 wing large, long, rather narrow, sigmoid behind. Surface having 

 on the body six or seven strong, high, nodulate, distant ribs, with flat 

 interspaces each of which bears five or six minute irregular minor 

 ribs ; on the front wing, three or four closer and more confluent 

 ribs ; and on the hind wing, ten or twelve small close ribs ; the 

 whole being crossed by very numerous, minute, regular, crenulated 

 growth-lines. Hinge with four strong, irregularly horizontal teeth 

 in front of the umbo, below which is a small deep muscle-mark. 

 Hind teeth unseen in English specimens.
