contains 13,804 specimens, and 209 models and preparations, rep- 

 resenting 3,755 species. The entire systematic collection of Gas- 

 teropoda, Pteropoda and Cephalopoda, now contains 34,681 

 specimens representing 5,094 species. The revision of the New 

 England collection of Mollusca has been finished by Mr. Henshaw. 

 It contains 1,500 specimens, representing 300 species. Specimens 

 have been received as donations, or in exchange, from Messrs. C. 

 B. Fuller, John Ritchie, Jr., E. W. Roper, and Dr. A. Shurtleff. 



Crustacea. 



Mr. J. S. Kingsley has helped Mr. Henshaw in the work of re- 

 vising the valuable collection of Crustacea he presented to the 

 society in 1881 and this work is now finished. It contains 2,900 

 specimens representing 400 species. 



Insects. 



The additions to this department have been unusually large. 

 First to be mentioned is the general collection of Mr. Edward Bur- 

 gess, announced in the last report. This consists of about 6,000 

 specimens and is especially useful for the New England material 

 and for a fine lot of European micro-lepidoptera. 



We have obtained through exchange a collection of about 1,000 

 Diptera, chiefly from New England, with some interesting forms 

 from Texas. This collection, when worked up, will be very useful, 

 as we are poorer in New England Diptera than in any other order 

 of insects. We have received by exchange lift}'' specimens of Hy- 

 menoptera from San Domingo, forty specimens of Brazilian Lep- 

 idoptera and a small lot (about seventy-five specimens) of European 

 Hemiptera. All of these were selected to fill gaps in our series. 



Dr. H. A. Hagen and Mr. S. H. Scudder have, as usual, presented 

 specimens to this department. 



The reception of the Burgess collection made it necessaiy to re- 

 vise our New England collection. This has been done (though 

 the identification of the Hemiptera, Diptera and Hymenoptera is 

 incomplete) and the following summary shows the extent of our 

 series :
