Regular Meeting, March 19th, 1866.
President in the Chair.
Twelve members present.
Donations to the Cabinet: Sections of the Sequoia gigantea and a roll showing the annual growth of the “Old Maid,” one of the trees in the Calaveras grove of Big Trees; from Mr. Henry Hentsch.
Mr. Dall stated that Dr. Cooper had discovered, in the vicinity of Santa Cruz, Helix redemita, H. Vancouverensis, H. Columbiana, and H. arrosa; also, in the small rivulets near the town, Margaritana falcata, besides several univalves, and also an undetermined Helix, which may prove to be new. Mr. Dall also remarked that Rev. J. Rowell had obtained at Hayward’s, Alameda County, a number of specimens of Helix Cronkhitei, which is a new locality for that species.
Mr. Dall remarked that in dissecting a specimen of Trochiscus Norrissii, the position of which has for some time been doubtful, sufficient evidence was obtained to decide that it did not belong with the Proboscidians, to which group it had been doubtfully referred by several naturalists.
