* The two shells placed in this genus by Dr. Turton will, I think, be found 

 to belong to the genus Astarte and the minutissima, probably the immature shell 

 of the triangularis. 



f This is stated, upon the authority of Capt. Alexander, to have been found in 

 the coralline crag, but from the appearance of the locality I think there is at 

 present a doubt of its belonging to that formation : I found at the same place 

 Cyclostoma elegans, and Pupa marginata. Capt. A. kindly sent me a specimen, 

 which, by comparison, appears identical with that which is found so abundantly 

 in the lacustrine deposit at Stutton, on the banks of the river Stour, seven miles 

 south of Ipswich : whether this be the same as the common species from the Nile, 

 Cyrena consobrina, I will leave others to determine ; but there is one character in 

 the fossil in which it appears to differ from the recent, although amongst some 

 hundreds of specimens that I have procured, there is of course a great variety ; 

 the posterior side is always more angular than that of the recent, which in all 

 those that I have seen is truncated. Our shell appears to agree with Cyrena 

 Gemmellarii, Phil. Enum. Moll. Siciliae, t. 4. f. 3. 



% The umbo of this, from the coralline crag, is a little more produced, and ap- 

 pears to have been rather a thicker shell than the recent, which is the only dif- 

 ference that I can detect, while the specimens from the red crag preserve a 

 sort of intermediate character in that respect.
