The following list is intended to include only species not previously recorded from the re- 

 gion of Cape Hatteras between low-water mark and 50 fathoms, although in one or two in- 

 stances recorded species are mentioned where there is some v.iriation from the original de- 

 scription or doubt as to their identity. It is by no means complete, as there are still a num- 

 ber of species which have not been satisfactorily identified. There is .also a large amount of 

 fine shell-saud which has not yet been assorted. 



At the end a list is given. of deep-water species found in not less than 40 fathoms, many of 

 which have not before been found so far south. 



A list of the dredging stations made by the Albatross in the region of Cape Hatteras, with 

 the date regarding them, is given on page 454. Eighty-four species of mollusca are enumer- 

 ated from less than 50 fathoms, including thirteen new species .and one new variety, which 

 are described and mostly figured. Descriptions of some of the old species are also given. The 

 new species are as follows :
