Fragmenta Phytographiæ Australiæ, by Ferdinand Mueller, Vol. III, from the author. Mr. Bolander stated that he had recently collected two grasses believed not to have been before found on this coast, though common in the Atlantic States, viz.: _Paspalum distichum_ (L.) along the shores of Clear Lake, covering large patches of ground, and _Leersia oryzoides_ (Swartz), along Cache Creek, of much larger size than he had met with in the East. He believed _Gastridium australe_, which covers almost every dry hill in the interior, to be indigenous. Dr. Behr made some remarks on the date of introduction of some foreign plants, now becoming very common in this vicinity, which he intends to make the subject of a future article.

Dr. Ferdinand Mueller was elected an Honorary member. Frederick Wideman, of Sinaloa, Alex. Drauphing of San Sebastian, and S. W. Morrell, of Mazatlan, were elected Corresponding members. Dr. Cooper exhibited specimens of _Lagomys princeps_, the “Little Chief Hare,” from the summits of the Sierra Nevada. He remarked that this rare animal lived about the limits of perpetual snow, and was so rarely seen that residents for several years near its resorts had never seen it. He found it quite common in a very limited district, though difficult to obtain, from its extreme shyness. Though before found in the Rocky Mountains near South Pass, and Salt Lake, where it is called “Coney,” this was the first record of its occurrence so far to the west and south. REGULAR MEETING, November 2d, 1863. President in the Chair. Twelve members present. Mr. W. G. Binney, of Burlington, N. J., George N. Lawrence, of New York, and William Cooper, of New York, were elected Corresponding members. Mr. Lorquin presented two species of California Jays for the Cabinet.
