Black Sea Mollusca. — By J. Gwyn Jeff'reys, LL.D., 

 F.R.S., &c. 



The Black Sea is Zoologically an off'set of the Mediter- 

 ranean, the latter and the Sea of Marmora being the links 

 connecting it with the North Atlantic. The Mediterranean and 

 the North Atlantic scarcely differ in their mollusca, as Dr. 

 Jeffreys has previously shown. 



The shells which are the subject of present notice were 

 dredged by Admiral Spratt in 1855 off Balaclava, and about 

 sixty miles south-east of the Danube. None of the species 

 mentioned, except Mytilus ediilis, are included by Middendorf, 

 in his ' Malacozoologia Rossica,' nor mentioned by Weinkauff. 

 The list contains six species, as follows : — Mytilus edulis, M. 

 phaseolinus , Cardium fasciatum, Scrobicularia alba var. cicrta, 

 Cerithiiim pusilbcm, and the new species, Trophon breviatus 

 Jeffreys, which is allied to T. muricatus, a Mediterranean species.
