ZOOLOGICAL LITERATURE. 
Oomobasu {Ceriphasia, Adams). Proc. Acad. Nat. Sc. Philad. 1864, p. 24. 
All the species are American j the synonymy is carefully given. 
Melania (^IJemisinus) wesselij Brot, Journ. Conch, p. 20, pi. 2. f. 2 ; locality 
doubtful. 
Schizostoma. Mr. Q. W. Tryon gives a synopsis of the species of the genus 
Schizostoma (Lea) = Melatoma (Anthony) = Oyrotoma (Shuttl.). Proc. Acad. 
Nat. Sc. Philad. 1804, p. 92. 
Melanopsis maroccana, Chemnitz, sp. {dufourii, F(§r.), Bourg. Mai. Alg. v. 
pi. 15. f. 12-26, pi. 16. f. 1-14, including several varieties. Enlarged figures 
of the living animal (f. 15, 16) are given ; it resembles much that of Melania, 
Melanopsis maresi, Bourg. 1. c. pi. 16. f. 21-24. This species, hitherto 
known in a fossil state only, has been found alive in the country south of 
Tunis by M. Buveyrier. Bourg. Mollusqnes de la Sahara.— tingU

LiTORINIDiE. 
Litorina pullata, Carpenter, Ann. & Mag. Nat. Hist. xiii. 1864, p. 477. Cape 
St. Lucas, California. 
Risella. M. Crosse has published a monograph of this genus, Journ. Conch, 
pp. 226-243, enumerating nine species (two of which were not known to 
Philippi when he published his monograph in the Malakozoologische Zeit- 
schrift, 1846). The author figures three species ; R. melanosioma (Gmel. sp.), 
pi. 11. f. 1; plana (Q. G. sp.), f. 2j bruni (sp. n., Crosse), from Spencer Bay, 
S. Australia, f. 3, p. 241. All the species are from Australia. 
Lacuna pen'recta, L. (? solidula, var.) compjacta, and L. variegata, Carpenter. 
Ann. & Mag. Nat. Hist. xiv. p. 428. Vancouver district. 
Fossarus. M. R^cluz has published “Observations sur le genre Fossar 
{Fossarus') Journ. Conch, pp. 247-251. An examination of the soft parts 
of the animal leads to the distinction of two sections within this genus, the 
one including the typical species, F. adansoni (Phil.), with the margin of the 
mantle entire and with a distinct velum in front of the tentacles^ the other, 
Clathrella, with the margin of the mantle crenulated and without velum, 
including F. costatus (Brocchi, sp.) and F. minutm (Mich.). 
Hr. Fischer adds a “ Note sur le genre ^ossai'us, suivie du catalogue dea 
especes,” ibid. pp. 252-260. He gives a short history of the genus, and pro- 
poses to retain it in the family of Litorinidae, associating with it a new genus, 
Ariadna, for Trichotropis borealis, and enumerates 41 species, five of which 
are European, two being found in the Mediterranean, two in West Africa 
(one of them identical with a Mediterranean species), two in the West Indies, 
eight on the Pacific shores of America (Panama and Mazatlan), seven in the 
tropical Indo-Pacific Ocean from the Red Sea to the Sandwich Islands and 
New Caledonia, and no less than nineteen in the Japanese Islands, which are 
due to the researches of Mr. A. Adams.
