The collection of Fulgoridae has been revised and re- 

 arranged. 



The collection of British Gall-Flies and Saw-Flies {Cynipidce 

 ^nd Tenthredinidw), formed by Mr. P. Cameron, and which 

 was the ground work of his Monograph published by the Ray 

 Society, was presented to the Trustees by Mr. F. Ducane 

 Godman. The whole of the specimens have been cleaned, 

 re-mounted where necessary, labelled with their localities, 

 and arranged in a new cabinet. 



Various families of British Diptera (Gonoindoi, Lej^tidce, 

 Momhylidce) have been revised and re-arranged, while the 

 accessions belonging to them have been determined, mounted, 

 labelled and incorporated. A number of genera of the 

 Tahanidce, Syrphidce, and Muscidce have been similarly 

 treated, and the working out and arrangement of the families 

 Ortalidce and Tryj^etldce has been commenced. The unin- 

 corporated accessions belonging to families from Fulicidce to 

 J^yrphidid have been sorted and arranged in drawers in sys- 

 tematic order. 



Various genera of exotic Stratiomyidcn have been re- 

 determined and ro-arranged ; while with the help of Mr. G. 

 W. Johnson, of Philadelphia, Pa., notes have been made on 

 the types of the North American species belonging to this 

 family described by the late Francis Walker. 



The greater portion of the Diptera exhibited in the Insect 

 Gallery has been examined and properly determined. 



A small collection of Diptera from Trinidad, obtained 

 from a flower of Aristolochia gigas has been worked out, 

 j&nd the results published. 



Crustacea.— The manuscript catalogue of Brachyura, which 

 was commenced last year, has been completed, but requires 

 revision before final arrangement. The accessions during 

 the year have nearly all been determined and incorporated. 



A revision has been commenced of the microscopic pre- 

 parations of " Challenger " Amphipoda, many of which 

 require to be remounted. Various Amphipoda have, from 

 time to time during the year, been named by Mr. A. O. 

 Walker. 



Vermes. — The exhibited collection of Annulata has been 

 remounted, and numerous explanatory labels prepared. 



The collection of Polychoita has been enlarged by the 

 addition of representatives of genera from the Mediterra- 

 nean not hitherto contained in the collection, the 

 determinations of the Zoological Station at Naples being 

 accepted. 



Various earthworms have been determined by Dr. Benham, 

 leeches by Dr. R. Blanchard, and land Planarians by Professor 

 Grafl-.
