* 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. 
+ 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 adoubt of its belonging to that formation: I found at the same place 
Cyclostoma eiegans, 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. Siciliz, t. 4. f. 3. 
t Theumbo of this, from the coralline crag, is a little more produced, and ap- 
_ to have been rather a thicker shell than the recent, which is the only dif- 
erence that I can detect, while the specimens from the red crag preserve a 
sort of intermediate character in that respect.
