FAUNA OF TRE SHALLOW WATER NEAR GAPE RATTER AS. 



The first and the last trips of the season were made to the waters off 

 Chesapeake Bay and Cape Hatteras. In that region, besides some in- 

 teresting hauls that were made in deep water, a few were made in shal- 

 low water, during the stormy weather encountered on the last trip. 

 These were near the coast, in 15 to 145 fathoms (stations 2107 to 2109, 

 2112 to 2114). They proved to be of great interest, for scarcely anj^thing 

 had been previously known respecting the fauna inhabiting the outside 

 waters, in moderate depths, off pur Southern Atlantic coasts north of 

 Florida, most of the inshore collecting in that region having been car- 

 ried on in the harbors and sheltered sounds, while the dredgings by the 

 "Blake" and "Fish Hawk" were mostlj' in deep water far from the 

 shore. 



From these few shallow- water dredgings made by the "Albatross" a 

 large number of interesting additions to the known Mollusca of the At- 

 lantic coast have been obtained. Many of these are West Indian spe- 

 cies, not known before from north of Cuba, while a considerable number 

 are undescribed. Among the interesting discoveries was a handsome 

 living Conus of good size, from 48 fathoms. It resembles the Conns De- 

 lessertii Eecluz. The general character of the Mollusca is decidedly 

 ''more tropical, or rather "warm-temperate," than that of the shore 

 fauna of the adjacent coast. But with the southern forms, such as. 

 species of Conus, OUva, Olivella, Marginella, Cancellaria, iSemicassis, So- 

 larium, &c, there are also many northern species, common on the New 

 England coast, but hitherto not known to live so far south. It appears 

 very strange to see West Indian and northern or even Arctic species 

 mingled together in the same haul of the dredge. The mildness 

 and unusual uniformity of temperature during the whole year, due to 

 the greatly diminished volume, or absence of the arctic current, over
