[77] ALBATROSS EXPLORATIONS. 579 
the inshore plateau, and to the effect of the Gulf Stream in winter, are 
doubtless the causes of this peculiar assemblage. 
These shallow-water shells, which are mostly of small size, have been 
studied with care by Miss K. J. Bush, who has identified many of the 
known species and described several of the new ones. I am greatly 
indébted to her for the accompanying list of the species already deter- 
mined, but the study of these shells is not yet completed, and this list 
must, therefore, be regarded only as a partial one.t 
The representatives of other groups were of less importance than the 
shells, but several interesting southern species of Echinoderms and 
Anthozoa were taken, of which the bathymetrical range is little known. 
Ameng these were specimens of the branched coral, Oculina implicata V., 
and the leaf-like Renilla reniformis Cuv. The southern shallow-water 
star-fishes, Luidia clathrata Say and Astropecten articulatus Say, also 
occurred in these localities, in 14 to 25 fathoms. During the more ex- 
tended explorations in the same region in 1884, Ophiothrix angulata and 
Amphiura elegans (= tenuis Ayres) occurred in 16 fathoms, while the 
curious West Indian Astroporpa annulata occurred several times, of 
large size, clinging to the Gorgonian, Titanidewm suberosum V., in 48 to 
68 fathoms. 
LIST OF THE SHALLOW-WATER MOLLUSCA DREDGED OFF CAPE HAT- 
TERAS RY THE “ALBATROSS” IN 1883. 
By Miss K. J. BusH. 
The following list is not intended:as a complete list of the shells of 
this region, but is nearly complete for the work of 1883. Many addi- 
tional species were dredged in the same region, in the autumn of 1884. 
The bathymetrical range refers only to the collection of 1883. Most of 
the commén species also occur in very shallow water in the harbor of 
Beaufort, N. C., or even at low-water mark. An asterisk (*) indicates 
specimens living; a dagger (+), dead shells only.

tAnother and more extensive series of dredgings in shallow water in the same re- 
gion was made by the ‘‘Albatross” in 1884, by which a much larger collection was 
obtained, including, besides many additional Mollusca, a great variety of interesting 
Crustacea, among which there are many species not before known from the Atlantic 
coast of the United States. The additions to the Brachyura are especially interesting 
and numerous. Many are Floridian and West Indian species.
