GEOGRAPHICAL DISTRIBUTION. 129
Pelagic mollusks, and especially Pteropods, often make their appearance in
places where they have never been observed before or afterwards; so in the
gulf of Naples in 1864 Clionopsis krohnii, in 1865 Spiralis recurvirostra, in
1869 Ilyalcea inflexa and Creseis acicula. Costa, Ann. Mus. Nap. iii. 1869.
Twenty-nine species of Mediterranean Cephalopods are enumerated by
Targioni-Tozzetti, Att. Soc. Ital. xii. pp. 587-598.
A very poor list of mollusks found in the Black Sea is given by F. Marcusen
in the-'Transactions' of the first meeting of Russian naturalists at
St. Petersburg, 1868, p. 178.
3. Red Sea.
Seventy-two species of sea-shells, collected in the bays of Suez and Akaba,
are enumerated by P. Fischer, who points out that some of them are identical
with or very nearly allied to others from the West Indies. J. de Conch.
xviii. pp. 161-179. One only, Nassa gibbosula (L.), is said to occur also
living in the Mediterranean. [See below, p. 134.]
A large number of sea-shells, collected by Mr. M'Andrew in the Red Sea
are enumerated (Ann. N. H. (4) vi. pp. 429-450), among which are 355
not contained in Issel's work; the new species among them are described
by H. Adams, 1. c. pp. 121-129, and P. Z. S. 1870, pp. 5-7, pi 1. figs. 1-11,
and pp. 788-793, pi. 48. figs. 1-19.
A list of 128 species of sea-shells collected in Annesley Bay, and nine
others obtained in the open sea off the south-east coast of Arabia, is given
by W. T. Blanford, Obs. Geol and Zool. Abyss, pp. 462-471.
4. Seas of India and Tropical Polynesia.
Scattered descriptions of apparently new species occur in the various periodicals,
but no paper treating of them separately.
5. Northern Pacific.
A. ADAMS gives a list of 87 species of Proboscidiferous Mollusks inhabiting
the seas of Japan. Besides 9 new ones and a large number of tropical
Indian species, there are some well-known European forms among them,
as Buceinum undatum, L., Gulf of Tartary; B. glaciate, L., Saghalien;
Purpura hcemastima (L.), Hakodadi; P. lapillus (L.), Hakodadi and other
localities; Nassa mutabilis (L.), Takanosima and Mososeki; the last is the
most remarkable, as in Europe it is confined to the Mediterranean. The
genus Leptoconchus is here first indicated from Japan in Madrepores at Kino-
O-Sima. Ann. N. H. (4) v. pp. 418-430.
The shells of Monterey are enumerated by J. G. Cooper; 206 species are
named, 126 of them have heen first observed on the shore, 80 first found by
dredging. Am. J. Conch, vi. pp. 42-70.
The species of Patella and allied genera occurring on the West Coast are
treated by Dall, Am. J. Conch, vi. pp. 227-282.
Several sea-shells from La Paz, California, collected by J. Pedersen, are
described and others mentioned by A. E. Verrill Am. J. Sc. xix. pp. 217-
227.
