 ANOMIA striata. 



Spec. Char. Suborbicular, convex, when old 

 contracted towards the beak; longitudinally 

 striated. 



Syn. Anomia Ephippium, Auctorum. 



-i HE fine striae that cover this fossil are very conspicu- 

 ous in the French specimens, and are alone sufficient to 

 determine it a distinct species : in the young state these 

 striae are not easily discoverable, it may then be readily 

 taken for A. Squamula, but the foramen does not extend 

 to the edge of the valve as in that species. 



A single valve of this remarkable shell is now and 

 then found at Barton ; figs. 2, 4 and 5 are from that 

 place, two of them through the kindness of the Rev. T. 

 Cooke. 



The small individuals fig. 1, were attached to Pinna 

 affinis, (tab. 313.) and the group fig. 3 to a Pectunculus, 

 both in the Sandstone of Bognor Rocks. It is not rare 

 in several parts of France.
