 re-mounted where necessary, labelled with their localities, 

 .and arranged in a new cabinet. 



Various families of British Diptera (Conojndce, Le2)tidce, 

 BornhylidcE) 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 

 'Ortalidoi and Tryj^etidce has been commenced. The unin- 

 'Corporated accessions belonging to families from Fulicidw to 

 SyrpJddce have been sorted and arranged in drawers in sys-

 the year have nearly all been determined and incorporated.
