than half way to the Bermudas, and nearly east of the coast ot 
Virginia, between N. lat. 36° 05’ 30” and 37° 48’ 30"; and between 
W. long. 68° 21’ and 71° 55’. 
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 off 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 off 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 fathoms ; 
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 large proportion of them. But there is still a 
large quantity of fine mixed bottom materials to be examined from 
the shallower dredgings. 
The results this year were highly satisfactory, both in the way of 
physical observations and zoological discoveries. 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 composing 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
