Cucullcea carinata, De Ranee : Geological Magazine, 1874, 

 p. 252. 



A familiar species represented by an impression of a left valve 

 contained in one of the fragments of Hoplites Benettianm. It is 

 of medium size, and well ornamented with the characteristic radiat- 

 ing costse, crossed by rather indistinct rugose lines of growth, 

 which are chiefly prominent near the ventral border ; the carina is 

 well defined, together wtth the oblique posterior area, which bears 

 a series of curved costse ; the summit or beak is strongly incurved 

 and anterior ; ligamental details not seen. This is quite a separate 

 form from J. Sowerby's Cucullcea carinata of a later date, which 

 has been united with the Cucullcea glabra, of Parkinson.
