NOTES. 



(a) M. Deshayes figures a specimen from the " Sables Inferieurs " of Bra- 

 cheux which he calls the C. semigranulosum. Sow., and gives as 

 synonymous the C. Plumsteadiense of the same author. M. Deshayes' 

 specimens must, however, be probably referred only to the latter 

 species of Sowerby; the first-named sjjecies of Sowerby is not therefore 

 identical with the species to which M. Deshayes gives that name. 



{b) These occur only in casts, which on a previous occasion were referred 

 to the C. globosa, Sow. ; but this shell is more equivalved and less 

 globose than the Barton species, and more resembles the French spe- 

 cies, which is found in the " Argile plastique " of Hilly, and has been 

 described, but not figured, by Nyst. 



(c) This shell was first referred to C. revoluta. Sow., of Barton, but it is 



more equivalved and the beak is less incurved. In my paper on the 

 Thanet Sands it was considered as the C. longirostris, Desh. ; but this 

 shell, which M. Deshayes quoted from the " Sables Inferieurs " of 

 Bracheux, was figured from a bad specimen, and the name has since 

 been restricted by this able conchologist to the species from the Gres 

 Moyens of Beauchamp. The former is therefore vmdescribed, and is 

 probably the same shell as that here described and named. 



[d) With the exception of the C. cuneiformis and tellinella, which are well- 



marked species, these Cyrencn form a very perplexing group. The 

 other three species here given, although in many cases presenting well- 

 marked and distinct characters, pass commonly into forms so nearly 

 resembling one another and the C. cuneiformis, that I almost hesitate 

 to adopt the specific distinctions here given. They have, however, been 

 adopted after a long and careful comparison of a very large series.
