to be admitted as a distinct species from the F. palumbanus of the 

 old continent. 



The President offered, in the name of Mr. Mead, a donation of a 

 suite of select specimens of English fossils. The Transactions of the 

 Physical Class of the Asiatic Society of Bengal ; the conclusion of 

 the third, and commencement of the fourth volume of the great 

 work on the Mammalia, by F. Cuvier and St. Hilaire, and other 

 works, were received this month, the first from the Asiatic Society. 

 Mr. A. Thompson was elected a resident member. 



September. — Dr. Graves presented minerals and fossils from Cu- 

 ba ; and the Rev. Mr. Robertson, minerals and shells from Greece 

 and the Levant. Dr. Feuchtwanger read a paper, describing the 

 new mineral called Aeschynite. Dr. Torrey read a letter from Dr. 

 Eights, containing a sketch of his^ observations during his recent 

 voyage to the South Seas. 



Mr. Halsey communicated some observations on the habits of an 

 insect which attacks the honey locust ( Ghditschia) in this vicinity, 

 the branches of which it completely girdles, but for what purpose is 

 unknown. Mr. Halsey considers it closely allied to, if not the same 

 with the Lamia amputator of St. Vincent's, described by Mr. Guild- 

 ing in the Linnean Transactions. Dr. Eights presented crustaceous 

 animals, found in a Cod, taken off Cape Horn, and bearing much 

 resemblance to the Trilobites. Several presents of insects, books 

 and minerals were laid on the table. 



October. — Dr. Torrey read a paper on a new and very tall species

 lingtoniana, in honor of the discoverer. Dr. T. also communicated a 

 description of a new species of Campanula, from New Orleans, C. 

 ludoviciana. The President gave a verbal account of certain re- 

 markable sutures which he has recently observed in the gneiss rocks 

 of this island. They are about a foot long, deep, parallel, and cross 

 the strata at right angles, differing entirely from the superficial 

 grooves already noticed, and such as cannot be accounted for on the 

 supposition of abrasion from bowlders. Mr. Cooper read a notice 

 of several North American birds, that appear to have changed or ex- 

 tended their habitation within late years.* Many interesting addi- 



* One of these is the Cliff Swallow, of which an interesting notice is given by Mr. 

 Woodruff, in the last No. of the Am. Journal of Science, p. 172. See Bonaparte's 

 Am. Orn. Vol. I.
