Shells collected by the U. S. Coast Survey Expedition to Alaska, in the year 1867.

BY ROBERT E. C. STEARNS.

George Davidson, Esq., connected with the Coast Survey service of the United States, who commanded the scientific department of the Alaska Expedition, very kindly tendered positions on his staff to the following members of the Academy: Dr. A. Kellogg, as Surgeon and Botanist; Theodore A. Blake, as Geologist; and W. G. W. Harford, as General Collector, by whom the species here enumerated were collected. My acknowledgments are due to Dr. J. G. Cooper, of San Francisco, for assistance in determining species; also to Dr. William Stimpson of Chicago, for similar service in reference to the Buccinidæ.

[36] In a note from Dr. Stimpson, he remarks in reference to this species: it “has not, as far as I am aware, as yet been reported from the Pacific.”

Mr. Bolander presented a paper by Mr. Lesquereux, entitled “A Catalogue of the species of Mosses found up to the present time on the Northwest coast of the United States of America, and especially in California,” which was referred to the Publication Committee and ordered printed in the Memoirs of the Academy.

Professor Whitney exhibited several of the maps in preparation at the office of the State Geological Survey, and gave a somewhat detailed account of the operation of the survey during the year 1866 and 1867, and of the progress in the publication department of that work. The statement made was in the main identical with that contained in the biennial letter of the State Geologist to the Governor, published by order of the Legislature then in session.

Dr. H. Gibbons exhibited a piece of pork erroneously supposed to contain trichinæ; he believed the entozoa in question were really Cysticerci. They have the appearance of soaked peas, and are not injurious when cooked.
