At the end of the season, while on his way south, Capt. Tanner 

 made another trip for the special purpose of exploring the shallow 

 water regions in the vicinity of Cape Hatteras, where a very inter- 

 esting fauna had been discovered by the Albatross in 1883. On this 

 trip the first three hauls (stations 2263 to 2265) were made oflf Chesa- 

 peake Bay, Oct. 18, in 70, 167, and 430 fathoms, with interesting 

 results; and 45 stations (2266 to 2310) were occupied October 19 to 

 21, in the region oiF Cape Hatteras. Of these, one (No. 2300) was 

 in 671 fathoms; four were in depths between 111 and 322 fathoms 

 (Nos. 2266, 2299, 2306, 2310) ; six were between 50 and 80 ftithoms ; 

 eight were between 30 and 50 fathoms ; three, between 20 and 30 

 fathoms; and twenty-three, between 7 and 20 fathoms. This shal- 

 low water region yielded a rich harvest of shells and Crustacea 

 unknown on our Atlantic coast, including a considerable number of 

 new forms. In the following list these shallow water mollusca, from 

 less than 60 fathoms, are not included, but many of them will be 

 enumerated in a subsequent paper by Miss K. J. Bush, who has been 

 able to determine a lai'ge proportion of them. But there is still a 

 large quantity of fine mixed bottom materials to be examined from 

 the shallower dredgings. 



The i-esults this year were highly satisfactory, both in the way of 

 physical observations and zoological discovei'ies. Large numbers of 

 additions were made to the fauna, including representatives of nearly 

 all classes of deep-sea animals. Many pelagic species were also 

 secured in the surface nets, and especially in the trawl-wings. 

 Among these there are some new forms and many others, including 

 some Pteropoda and Heteropoda, that have not previously been 

 observed so far north in the Gulf Stream. 



Character of the deep-sea deposits. 



Some very interesting and important discoveries were made in 

 regard to the nature of the materials com2:)osing the sea-bottom 

 under the Gulf Stream at great depths. These observations are 

 very important, as regards the distribution of the animal life, which 

 often depends directly upon the nature of the bottom, and of great 

 interest from a geological point of view. Some of these observa- 

 tions are contrary to the experience of other expeditions, and not in
