The 15th and 16th parts of Hidalgo’s Moluscos manuos de Espana, 
&c. [not seen by the Recorder], apparently contain chiefly bibliographical 
lists and 12 coloured plates : most of the species figured are well known 
as Mediterranean, the few apparently new, or rather rare and criUcal, 
will be mentioned infra. Abstract in J. de Conch, xxviii. p. 274. 
The number of the species of marine Mollusc a peculiar to the Mediter- 
ranean, and absent from the adjacent parts of the Atlantic, has been 
reduced by the recent dredging expeditions from 222 to 181, and will 
probably become still more reduced in future. Jeffreys, Rep. Brit. 
Assoc. 1880, pp. 601 & 602.

terranean, by E. Dubreuil, Rev. Montp. (2) ii. pp. 304-313. 
General remarks on the Mediterranean Mollusca exhibited in the 
Aquarium of the Zoological Station at Naples, by Doiirn & Schmidt- 
LEIN, Leitfaden fiir die Aquarieu der zoologischen Station zu Neapel, 
1880, pp. 39-52. 
49 species of Oephalopods, 19 of Pteropods [including probably larvie of 
Gastropods], and 12 Heteropods, including Janthina and Sagitta [!], 
enumerated by N. Tiberi, Bull. Soc. mal. Ital. vi. pp. 1-49, who also 
begins a paper on the known Nudibranchia of the Mediterranean, giving 
a full account of the previous literature, and discussing the family Dorid- 
idce and Tritoniidce, 1 c. pp. 182-224. 
The Mediterranean species of Pleurohranchus discussed by Vayssiere, 
J. de Conch, xxviii. pp. 205-216. 
A list of 42 Bivalves, 6 Solenconchce, 50 Gastropods, 6 Heteropods, and 
15 Pteropods (the two latter chiefly dead specimens), dredged in depths 
about 300 metres, between Palermo and Utica, is given by Monterosato, 
Bull. Soc. mal. Ital. vi. pp. 51-82. He points out the considerable 
analogy between the deep sea fauna of the Mediterranean and that of 
the British Islands and Norway, and also with that of the tertiary beds 
of the Monte Pellegrino and Ficarazzi ; 30 of the enumerated species are 
designed by him as being also Norwegian, 13 more British, 17 tertiary 
fossils of Italy. Special attention is paid to the synonymy of the less 
known species. 
Seven marine species, all well known, from the coast of Sardinia, 
enumerated by P. Magretti, Atti Soc. Ital. xxi. p. 451, and xxiii. pp. 20, 
21, 29, 30, 31, & 40.
