DAVIS : FOSSIL FiSH-REiMAlNS, (.'ULTRA, IRELAND. 
described. Having reference to its long and slender outline the 
specific name of A. attemiatus is suggested to distinguish this species. 
Cwlacanthus, sp. 
Several bones of Co^lacantlms have been found. Those most 
readily distinguishable are the operculum, a jugular plate, frontal 
bones of the external surface of the head, and a portion of the 
shoulder girdle. With the exception of the jugular bone they are 
all exposed on the under surface. The jugular plate has the external 
surface exposed : it possesses the characteristic ornamentation of the 
genus. 
The plates of Coelacanthus were found associated with a number 
of scales of moderate size, said to be a species of Holoptychius : I have 
not seen them.
