In the Zoological department, the Curator stated, that a few valuable additions had been made to the collection during the year 1862; but that much difficulty was experienced in arranging them, from the limited space and means of the Academy. The alcoholic specimens have not been rearranged during the year; some are in bad condition. All has been done which could be, towards preserving the specimens in this department, with the means at the command of the Curator. In the absence of the Curator of Conchology (Dr. Trask) it was stated, that the collection of shells had been arranged, and labeled, and placed in cases during the year; the accommodations of the Academy, however, do not admit of their being displayed. The Curator of Mineralogy (Mr. Hanks) has removed from the city since the last annual meeting; but previous to removing, he had made considerable progress in rearranging and labeling the collection of minerals and ores, and it is now in better order than it has ever before been. The Librarian reported that valuable additions had been made to the Library during the past year; chiefly through the instrumentality of the Smithsonian Institution. The books are in good order; but many of them need binding, and the want of room renders it impossible to place them where they can be easily got at by the members. The committee on nominations reported the following list of officers for the year 1863, which was duly elected: PRESIDENT. COL. L. RANSOM. VICE PRESIDENTS. J. N. ECKEL, M.D., J. B.

Donations to the Cabinet were received as follows: By Dr. Cooper—Specimens of _Purpura septentrionalis_, from San Francisco, and others from Oakland, of larger size—the latter not being natives of this Bay, but brought from Shoalwater Bay, W. T., in cargoes of oysters. By Mr. Bloomer—A collection of specimens of wood. Dr. Cooper exhibited a specimen of coral, of the genus _Porites_, probably an undescribed species. This mass of coral was drawn up by a fisherman, from a depth of four fathoms, at the Farallones, and deposited in the office of the Geological Survey by Mr. Lawson, of the Coast Survey. The same species had been previously obtained by Dr. Cooper in the Bay of Monterey, but it had never been found so far north before. REGULAR MEETING, JANUARY 19TH, 1863.
