B. Progress and arrangement of the Collection of 

 Crustacea. 



It is difficult to trace the early history of the collection of 

 Crustacea; all that can be said is that in 1835 there were a few 

 hundred dried specimens, probably without any definite attempt 

 at arrangement. 



In 1847, a list of Crustacea (12mo, 140 pp.) was prepared 

 by A. White; in 1855, T. Bell made a catalogue of the 

 Leucosiadse (12mo, 24 pp.), planned to be the lirst part of a 

 catalogue of Crustacea ; in 1862, C. Spence Bate made a 

 catalogue of the Amphipodous Crustacea (8vo, 399 pp., 58 

 plates). In 1850, A. AVhite published a list of British Crustacea 

 (12mo, 141 pp.). 



From 1872 to 1886, Mr. E. J. Miers worked at the 

 collection and made notes for a catalogue of Brachyura, in 

 addition to a number of faunistic reports, and monographs on 

 various groups or genera. 



In 1895, 1896, and 1897, F. Jeffrey Bell prepared a 

 complete MS. list of the known species of Brachyura, and 

 catalogued and arranged the specimens in the collection. This 

 catalogue is constantly kej^t up to date, and, as it is paged and 

 indexed, it is of use to outside workers. 



In 1897, Dr. Alcock, Major I.M.S., made a catalogue of 

 the spirit specimens of Penens, by which the collection was 

 arranged. 



In 1896 and 1897, Mr. Edmund Aikin made a revision of 

 the mounted specimens of Amphipoda of the " Challenger" 

 which had been originally mounted inadequately ; and in 1897 

 and 1898 he made a similar revision of the Copepoda. 



In 1900 a revision of the collection of Le/padidm was made 

 by Prof. Gruvel. 



During the later years of the century the assistance of 

 Dr. De Man, Dr. Budde-Luncl, and Mr. A. O. Walker was 

 asked and gladly given in working out respectively specimens of 

 Paldemon, of Isopods, and of Amphipods. 



It is estimated that there are 36,500 specimens in the 

 collection, of which 31,000 are determined ; the number of 

 species is about 4,500.
