BRITISH FOSSILS, 



the ventrals 10, and the dorsal and anal 12. The caudal fin is 

 bifurcate, the lower lobe being rather larger than the upper. The 

 scales are oval, and their surface marked by numerous fine concen- 

 tric lines, as in all the other species of the genus. 



Affinities. — This species is distinguished from Lepiolepis concen- 

 tricus by the sculptured preoperculum, the greater tenuity of 

 the scales, and the smaller size of the head. It has some resem- 

 blance to Leptolepis Knorri, found at Solenhofen, but has the 

 head proportionately larger, the apophyses of the caudal vertebrae 

 less inclined, and the form of the vertebras very distinct. I have a 

 specimen of Leptolepis, found in a liassic bed near Curcy in France, 

 which very much resembles this species. 



Locality. — All the specimens I have seen of this species belong to 

 Mr. Moore, and were found by him in a bed of light-coloured lias 

 near Ihuinster.
