Polagic molluslts, and especially Pteropods, often make their appearance in 
places where they have never been observed before or afterwards ; so in the 
gnlf of Naples in 18G4 Clionopsis hrohnii^ in 1806 Spiralis remrmrostra^ in 
1809 Ilyalcea injlcxa and Crescis acicula. Costa, Ann. Mus. Nop. hi. 1809. 
Twenty-nine species of Mediterranean Cephalopods are enumerated by 
Targioni-Tozzetti, Att, Soc. Ital. xii. pp. 687-698. 
A very poor list of mollusks found in the Black Sea is given by F. Mar- 
cusen in the ‘Transactions’ of the first meeting of Russian naturalists at 
St. Petersburg, 1808, p. 178. 
3. Red Sea. 
Seventy-two species of sea-shells, collected in the bays of Suez and Akaha, 
are enumerated by P. Fischer, who points out that some of them are iden- 
tical with or very nearly allied to others from the West Indies. J. de Conch, 
xviii. pp. 101-179. One only, Nassa gihhosula (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. II. (4) vi. pp. 429-460), among which are 366 
not contained in Issel’s work ; the new species among them are described 
by II. Adams, 1. c. pp. 121-129, and P. Z. S. 1870, pp. 6-7, pi. 1. figs. 1-11, 
and pp. 788-793, pi. 48. figs. 1-19. 
A list of 128 species of sea-shells collected in Anncsley 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. 402-471. 
4. Seas of India and IVopical Polynesia. 
Scattered descriptions of apparently new species occur in the various peri- 
odicals, but no paper treating of them separately. 
5. Northern Pacific. 
A. Adams gives a list of 87 species of Proboscidiferous Mollusks inhabit- 
ing 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 Buccinum undatum, L., Gulf of Tartary ; B. glaciale, L., Saghalien ; 
Purpura heemastvna (L-), Ilakodadi ; P. lapillus (L.), Ilakodadi 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 atKino- 
0-Sima. Ann. N. H. (4) v. pp. 418-430. 
The shells of Monterey are enumerated by J. G. Cooper; 200 species are 
named, 120 of them have been 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 Dali, 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.
