TuE FAUNA OF THE GULF STREAM AT GREAT DEPTHS.*—The inves- 
tigations ordered by the new Superintendent of the Coast Survey, Profes- 
sor Pierce of Harvard College, into the marine fauna of the Gulf stream, 
in connection with the regular duties of the survey, have begun to produce 
its natural result, in such valuable contributions to science, as we have 
now before us. The line of the present survey was “in a section between 
Key West.and Havana, incidentally with the purpose of sounding out the 
line for the telegraph cable.” ‘Although the work was interrupted, and 
the casts made with the dredge few, “the interesting fact was disclosed, 
that animal life exists at great depths, in as great a diversity and as great 
an eee as in shallow water.”, By two casts in two hundred and 
venty fathoms off Havana, Crustacea and Worms, numerous dead shells - 
a Gasteropods oer Pteropods, vin Terebratule, and seven species of 
ozoa, besides Echini, Starfishes, and an abundance of Corals, Hydroids, 
and Foraminitere were taken. Only one species of sea-weed, however, 
was mixed with this luxuriant animal life, which corresponds with especie 

ndred and vini fathoms, by at pyi two species known to be-

attempt are certainly very interesting and important to — zoology,
