good progress. The arrangement of the collection of Birds' Eggs, 

 entrusted to Mr. Seebohm in 1891, was completed. The eggs, 

 46,900 in number, were named and entered in a MS. list ; they 

 fill 33 thirty-drawer cabinets. 



The large increase of the collection of Arachnida (especially 

 after the purchase of the Keyserling Collection) rendered it 

 advisable to transfer the care of the Crustaceans from that 

 section to the Assistant in charge of the Echinoderms and Worms. 

 The whole of the alcoholic specimens of Crustaceans were re- 

 arranged in a general manner, and ready access to any of the 

 genera which may be required was secured. 



The arrangement of the W. K. Parker Collection of Fora- 

 minifera was completed. 



GUIDES, CATALOGUES, AND DESCRIPTIVE PAPERS. 

 (1893.) 



The demand for the guide-books continued to be satisfactory, 

 so that new issues or editions of those published were frequently 

 required; in the year 1893 a new edition of the Guide to the 

 Mammalian Galleries as well as the following Catalogues were 

 published : 



Catalogue of Birds. Vol. 21. By T. Salvadori. Pp. 676, 

 with 15 plates. 



Catalogue of Birds. Vol. 22. By W. R. Ogilvie-Grant. 

 Pp. 585, with 8 plates. 



Catalogue of Snakes. Vol. 1. By G. A. Boulenger. Pp. 448, 

 with 28 plates. 8. 



Illustrations of Lepidoptera Heterocera. Part 9. By 

 G. F. Hampson. Pp. 182, with plates 157-176. This part was 

 devoted to the Macrolepidoptera Heterocera of Ceylon, and was 

 the last of the series, the entire series being estimated to contain 

 illustrations of about 1900 types in the British Museum. 



Catalogue of Madreporarian Corals. Vol. 1. The Genus 

 Madrepora. By G. Brook. Pp. 212, with 35 plates. 1893. 4. 



Besides these works published by the Trustees, the incorpora- 

 tion of recent additions and the work of arrangement generally 

 gave rise to the usual crop of incidental papers published in 

 periodicals, viz. : 



Eight papers on Mammalia, by Oldfield Thomas. 



Two papers on Birds, by R. Bowel ler Sharpe and W. R. 

 Ogilvie-Grant. 



Two papers on Reptiles and Fishes, by A. Giinther.
