The following list is intended to include only species not previ- 

 ously recorded from the region off" Cape Hatteras, between low- 

 water mark and 50 fathoms ; although in one or two instances 

 recorded species are mentioned, where there is some variation from 

 the original description, or doubt as to their identity. It is by no 

 means complete, as there are still a number of species which have 

 not been satisfactorily identified. There is also a large amount of 

 fine shell-sand, which has not yet been assorted. 



The lists used for comparison are "Mollusca of Beaufort, N. C," 

 by Dr. Wm. Stimpson, published in the American Journal of Science, 

 vol. xxix, p. 44, 1860; "Natural History of Fort Macon, N. C, and 

 Vicinity (No. 2), by Dr. Elliott Coues, published in Proc. Acad. Nat. 

 Sci. Philadelphia, p. 120, July, 1871 ; " American Marine Conchol- 

 ogy/' by Geo. W. Tryon, Jr., 1873 ; and " Natural History of Fort 

 Macon, N. C, and Vicinity" (No. 5), by Drs. Elliott Coues and PI. C. 

 Yarrow, published in Proc. Acad. Nat. Sci. Phila., p. 1, August, 1878. 



At the end, a list is given of deeper-water species, found in not less 

 than 40 fathoms, many of which have not before been found so far 

 south. Such northern species have an n before them. 



To Prof. A. E. Verrill my thanks are especially due for valuable 

 advice in the preparation of this paper and for kindness in furnish- 

 ing books of reference,
