arrangement of the genera Heliocopris, Go'pris, Phanceus, 

 Eurysternus, and OnifAs, and the family Oalerucidoe] 



7. The arrangement of the Lepidoptera has made con- 

 siderable progress. The crowded state of the drawers contain- 

 ing the NymphalidcB, Euplmina, and Limnaina rendered 

 necessary a complete rearrangement and expansion of . these 

 groups to receive the " Moore " Collection and other numerous 

 additions. The arrangement of the tribes Noctuites and 

 Geometrites has been continued, all corrections of synonymy 

 in the former being entered in the " Catalogue " and published, 

 and a manuscript list of the latter prepared at the same time. 

 The Lepidoptera Heterocera of Ceylon, presented by Mr. 

 E. E. Green, have been incorporated and thoroughly studied 

 with the view to the publication of a complete f aunistic cata- 

 logue, as stipulated by the donor. 



During the progress of rearranging collections which had 

 been previously catalogued many of the specimens are re- 

 moved from their former position in the cabinets, sometimes 

 to different families. As this may give rise to difficulties for 

 the student who wishes to examine historically important 

 specimens, the plan has been adopted to distinguish such 

 specimens by special labels ; and, besides, a list is being pre- 

 pared, especially of the Walkerian types, showing the position 

 which they occupy at present in the system. 



8. The study and labelling of Walker's types of Syrphidce 

 has been completed, and the rearrangement of that family 

 commenced ; all the specimens have been remounted so as to 

 bring them up to one standard height. In the collection of 

 British Diptera the specimens of the small families Hippobos- 

 cidce SiTOid Oestridcv have been determined and arranged. 



9. Fourteen families of Ovthoptera have been rearranged 

 and determined, and part of the new species described ; the 

 study of the " Green " Collection of Ceylonese Rhynchota 

 has been completed, and the new species, amounting to about 

 100, have been described. 



10. The additions to the collections of Echinoderms and 

 Worms have been named and incorporated, and the manuscript 

 list of the former has been kept up to date. The revision of 

 British Echinoderms has been continued. The accessions to 

 the Anthozoa have been named and incorporated, as far as the^ 

 space at present available permits. A critical examination has 

 been made of the difficult and numerous group of Madre- 

 poridoe, and some 500 specimens have been named and 

 arranged, after a comparison with the types existing in 

 continental museums. 



11. A reference collection for the use of students, con- 

 sisting of over 2,000 microscopic slides of Polyzoa, has been
