GEOGRAPHICAL DISTRIBUTION.

A list of the Ceplialopods of the Mediterranean is extracted from the 
papers on the same subject by Targioni-Tozzetti in 1869 (Zool. Rec. vii. 
pp. 117 & 129), and the diagnoses of the then new species copied. Gervais, 
J. Zool. i. pp. 193-195. 
lUach Sea. 13. Ulianin gives a list of 43 shellj’^ Gastropods, 40 Bi- 
valves, and 5 Nudibranchs, observed hitherto in the Black Sea, all of which, 
with two or three exceptions, are also known from the Mediterranean. Mat. 
Faun. Black Sea, pp. 80-88. 
4. Eastern North America. 
Out of the 282 species of marine mollusks enumerated in Gould’s Report 
on the Invertebrata of Massachusetts, 2nd ed., J. G. Jeffreys claims nearly 
one half (136) as identical with European species ; viz. 60 Bivalves out of 
107, all 3 Brachiopods, 79 Gastropods out of 102, 3 Ileteropods and Gastro- 
pods out of 5, and not one of the 6 Gephalopods. Others are at least nearly 
allied to the European species. Ann. N. H. (4) x. pp. 237-247, and Rep. 
Br. Assoc. 1872. 
Some Mollusca found by dredging round the island of Anticosti, Gulf of 
St. Lawrence, are enumerated by J. F. White aves, Ann. N. II. (4) x. 
pp. 348-361, and Rep. Brit. Assoc. 1872. 
5. Southern Atlantic. 
36 sea-shells from St. Helena, collected by J. 0. Melliss, are enumerated 
by J. G. Jeffreys, Ann. N. II. (4) ix. p. 264. Among them are 6 appa- 
rently peculiar, to which is to be added Purpura helena (Q. & G.) as a 
seventh, 3 limited to W^estern Africa, 7 common to Western Africa and tlie 
Mediterranean, 1 South-African, 3 Northern, 4 from the Indian Seas, and 4 
of very wide distribution. Martens, Nachr. mal. Ges. 1872, pp. 69-61. 
The few shells known from the island of Ascension are mentioned by 
Martens, Mal. Blatt. xix. p. 39. 
The shells collected on the shores of Tierra del Fuego^ in the Magellan 
Straits, and on the Falkland Islands, during the expeditions of Capt. Cook 
and Bougainville towards the close of the last century reviewed. Id. ibid. 
pp. 5-10 and 51-62. 
6. Red Sea, 
II. C. W. Weinkauff discusses the geographical distribution of the shells 
of the Red Sea, chiefly those dredged by M'Andrew, and comes to the con- 
clusion that many of them have a wide area. 19 species are, according 
to him, also found in the Mediterranean. Nachr. malak. Ges. 1872, 
pp. 33-43. 
16 new species of shells, collected by M‘Andrew in the Red Sea, are 
described by II. Adams, P. Z. S. 1872, pp. 9-11.

JiCKELi. Mal. Blatt. xx. p. 121. 
7. Indian Ocean. 
20 new species of marine shells from Ceylon, Mauritius, and Pooree, Bay 
of Bengal, are described by G. and II. Ne\tll. J. A. S. 13, xxxix. 1871, 
part 2. pp. 1-11, pi. 1.
