of Georgia; Dr. Bibb, of Russellville, Kentucky; Dr. Barratt, of Abbe- 

 ville, South Carolina; Dr. Wormlej; of Columbus, Ohio ; Dr. Stevens, 

 of Olean, New York, and many others. One of the most important 

 additions consists of a series of nineteen species of Cyprinodonts, 

 labelled by Prof. Agassiz, and serving as types of the paper on this 

 family which he proposes to present to the Institution. Numerous 

 species of Nerth European fishes were presented by the Swedish 

 Academy of Sciences, Stockholm. 



Invertebrates. — Very important additions have been made to the 

 aquatic species of invertebrates from various sources. Among the 

 most valuable are those sent from the Tortugas by Lieut. Wright, em- 

 bracing a large number of new and rare forms. A collection of similar 

 extent, from the coast of Carolina, was forwarded by Lieut. Kurtz. 

 Unionidce have been received from Col. Wailes, of Mississippi, and 

 Prof Saflbrd, of Tennessee, in large numbers. A small collection of 

 land shells, from Oregon, was presented by Dr. Shumard : out of four- 

 teen species furnished, six are new to science. A very important addi- 

 tion to the collection consists of a series of eighty species of shells from 

 Greenland, presented by Mr. Christian Drewsen, of Copenhagen. 



The insects received have been few in number, and these principally 

 from Mr. Fairie, who sent quite a large collection of Lepidoptera and 

 Colenptera. Many species of Orthoptera were procured on Red river 

 by Captain Marcy, and in Texas by Mr. Lindheimer. 



Fla?its. — A collection of plants of Delaware county, Pennsylvania, 

 was presented by the Delaware County Institute. A suite of plants, 

 collected by Lindheimer in Texas, was obtained through Dr. Engel- 

 mann. Dr. Shumard sent a small collection from Oregon. Valuable 

 donations of algas were made to the Institution by Miss Brewer, 

 Lieut. Kurtz, &c. A small series belonging to Lieut. Lynch's col- 

 lections on the shores of the Dead Sea was presented by Hon. J. P. 

 Kennedy. 



Fossils and minerals. — The Commissioner of the Land Office has 

 deposited with the Institution additional specimens of fossils from the 

 Minnesota survey, collected by Dr. Owen, including some of the 

 vertebrate remains from Nebraska. Infusorial earths from Virginia 

 have been received from Prof, William B. Rogers and Dr. Beck. A 

 suite of coal plants was sent from the mines above Harrisburg, Penn- 

 sylvania, and a series of silurian fossils from Dr. Stevens, of Olean. 

 Remains of fossil elephant, from near Wheeling, were presented by 

 Mr. Alfred Sears, and of mastodon, from Fort Gibson, by Mr. B. 

 Marshall. Lieut. Gilliss forwarded a very interesting collection of 

 fossils from Chili. The principal minerals received consisted of gold 

 and silver ores from Mexico, presented by Dr. Jarvis, together with 

 copper ores from Chili, by Lieut. Gilliss. 



Ethnology. — Various remains of the North American Indians have 

 been received by the Institution during the year; but much the most 

 important addition in this department is to be found in a large number 

 of axes, arrow-heads, and other stone instruments, from Denmark, 

 presented by Prof. C. C. Rafn, of Copenhagen ; thus affording an 

 interesting opportunity of comparing the closely allied implements 

 used by the aborigines of Europe and of North America.
