By Exchange, 



"In Insects we have continued the former exchanges, and a larger num- 

 ber of individuals and institutions have entered into correspondence with 

 us than in former years. From fifteen different institutions and individu- 

 als we have added to our collections, in this manner, nearly 3,000 speci- 

 mens and over one thousand species. Returns have been sent to ten 

 different institutions and individuals, the number of specimens sent 

 away amounting to about 900 specimens, representing four hundred 

 species. 



There have been purchased from the Gray Fund over one thousand 

 species, numbering more than 3,500 specimens. 



For the Crustacea and Annulata the exchanges and the Gray Fund 

 have added only a very limited number of specimens, viz. : 270 specimens 

 of Crustacea, of 46 species, and 160 specimens of Annulata, of 33 species. 



Report on the Collection of Mollusks, by John G. Anthony. 



The Assistant Curator of Conchology, in rendering his 

 Annual Statement of the condition of his department, would 

 call attention to the unusual activity which has prevailed 

 therein since the date of his last report. This has been owing 

 to a variety of causes, prominent among which may be men- 

 tioned the reception of large and numerous contributions from 

 our Brazilian expedition, which, coming as they did, mostly in 

 alcohol, required more than usual care and attention to place 

 them in a safe condition. They have added, however, 374 

 species and 22,836 specimens to our collection which are of the 

 most desirable character, not only for our own collection, but 

 also for our foreign correspondents. 



During the current year our exchanges have yielded us 

 1,659 species and 51,208 specimens, which is an increase over 

 the number derived last year from the same source, the num- 

 ber of specimens being nearly fourfold the present year. Upon
