PTEROPODA. 
Capt. G. E. Fryer has given an interesting aeeoimt of his 
observations on pelagic Mollusca, chiefly Pteropods. Out 
of 31 species, 17 are common both to the Atlantic and the Indo- 
Paeific Ocean, 4 peculiar to the Atlantic, 8 to the Indo-Pacific, 
2 to the Southern Ocean, viz. Balantium recurvum (Bens.) 
and Balantium australe (Orb.), in latitude 38°-42° S. ; 12 species 
prove to be strictly nocturnal, the best time for catching them 
being the middle watch; 7 are crepuscular and nocturnal; 12 
others indifferent to solar influence. Journ. Asiat. Soc. Bengal, 
vol. xxxviii. pp. 259-264, with a table and map.

[ Clione) Clio horealis (Pall.) has been found at Portland, Maine, from the 
beginning of April until May 7, 1868. Its appearance is ascribed to the un- 
usual severity of the season. There is no record of its occurrence in those 
waters previously to 1833, when it was observed in the vicinity of New 
York. Proc. Portl. Soc. Nat. Hist. i. part 2, 1869, and Am. Journ. Conch, v.
