In the 'Ann. Lye. N. H. New York,' 1861, p. 287, the Eev. J. Eowell, of 



San Francisco, describes the second species of Faim * discovered on the 

 "western slope, viz. " P. CuUfornka, Eow., San Francisco : plentiful." 



On February 4th, 18(J1, Dr. Wesley Newcomb published (Latin) dia- 

 gnoses of the following Caliturnian Pulmoiiates in the • Proceedings of the 

 Cal. Ac. Nat. Sc.,' vol. ii. pp. 91-94. A second Part baars date March 18th,

91. Helix BndffestifNewc. San Pablo, Cal. 1 sp. Distinct fi-om all described forms. 

 „ Ileliv Traskii, Newc. Los Angelos, Cal. " Distinguished from H. Thouarsii 



at a glance." 



92. Vitrina Pfeijferi, Newc. Carson Valley. More rounded than diaphana, Drap. 

 94. Pmdimn occideiitale, Newc. Ocean House, S. Francisco, Powell. 



103. Helix Carpenteri, Newc. Tulare Valley, Mus. Cal. Ac. Belongs to the Cy- 



clostomoid group, and has the aspect of a desert species. [Quite distinct 

 from H. CarjKnteriuna, Bland, Florida.] 

 „ Helix Ayresiana, Newc. Northern Oregon ; Mus. Cal. Ac. Resembles H. 

 reticulata, Pfr., a Califoruian species not identified by the author.

In the * Proc. Ac. Nat. Sc. Philadelphia, 1861,' pp. 367-372, Mr. W. M.. 

 Gabb published " Descriptions of New Species of American Tertiary Fossils," 

 in which occur several Californian shells. The authorities for the localities 

 are not given, and the diagnoses are in English only. Considerable confusion 

 often arises fi'om the study of tertiary fossils without knowledge of recent 

 shells, and vice versa. Mr. Gabb's Avritings on the Cretaceous fossils of Ame- 

 rica display an ability with which this paper is perhaps not commensurate. 

 Some errors which had been found very difficult to understand are here cor- 

 rected by the author himself, who regrets the incompleteness of his earlier 

 work.

In the ' Proceedings of the Calif. Ac. Nat. Sc' for April 7th, 1862, pp. 170- 

 172, Mr. "W. M. Gabb published detailed English " Descriptions of two Species 

 of Cephalopoda in the Museum of the Academy," of which one, Oni/c7ioteuthis 

 fusiformis, is said to be from Cape Horn, the other from California. 



170. Octopus punctatus, Gabb. Common near San Francisco. Also abundant in 

 Scammon's Lagoon, Lower California, Capt. C. M. Scammon. Arms more 

 than seven feet long, Dr. W. O. Ayres. " Differs from O. meyalocyatkus, 



* That the race of small Pupa is very ancient on the North American continent, as in 

 Europe, is evident from the very interesting discovery, by Prof. Dawson, of a fossil Pupn, 

 in situ, nestling in an upright tree, fossilized in the Nova Scotian coal-beds; which can 

 scarcely be distinguished, even specifically, from some living forms.
