P. Fischer makes some important additions to his former lists of the

Note on dredging off Brest in 120-180 metres by Commr. Vignes, 
enumerating Venus ovata (Penn.), Cardium minimum (Phil.), and Trochus

2. Mediterranean Sea. 
The Marchese T. A. di Monterosato gives a fresh list of all the 
recent shells of the Mediterranean, including the additions from 
his own and other dredgings, and the synonyms of later years, 
noting by abbreviations the zones of depth in which the species 
are found, and their geographical range in the Atlantic. There are 
273 species of Bivalves, 11 Solenoconchce^ 560 other Gastropods (only 
shell-bearing species are enumerated), 19 Pteropods, and 1 Cephalopod 
{Ai'gonauta). He thinks that still more remain to be discovered. Atti 
Acc. Palerm. 1875, pp. 1-80. 
J. G. Jeffreys enumerates 80 species of shell-bearing Mollusca found 
in the Mediterranean by the la^t deep-sea dredging expeditions, and not 
included in Monterosato^s catalogue of 1872, thus bringing the total 
number of Mediterranean shells, excluding the doubtful and pretended 
species, up to 766 ; Kep. Br. Ass. for 1874, pp. 111-116.
