DEPARTMENT OF ZOOLOGY. 117 



Mr. J. L. Bonhote's collection of Moths from the Bahamas 

 has been worked out. 



The Assistant in chai-ge of the Diptera collection has 

 devoted the greater part of his time to a study of the Tsetse - 

 flies {Glossina) upon which he has prepared a Monograph. 



Numerous accessions of British and Exotic Diptera have 

 also been incorporated. 



Crustacea. — A few additions have been made to the mor- 

 phological series and a few supplementary labels added. The 

 difficult task of colouring the dried specimens with the tints 

 possessed during life is being slowly continued, as is also 

 the addition of specimens to the systematic series. The re- 

 arrangement of the dried study collection has been proceeded 

 with, and all the Brachyura have now been reset in cabinets, 

 and arranged so that examples of the same species are 

 together, whatever their size. It has not been possible to 

 continue the re-arrangement of the spirit collection, but it is 

 hoped that funds will be available for completing the cases 

 in the new room during the ensuing year. A MS. Catalogue 

 of the known species of Anomura ha? been prepared, and all 

 specimens in the collection have been entered in it. Occasion 

 was taken of the visit of Dr. Hansen to go through the 

 spirit collection of Stomatopoda. The Stomatopoda and 

 Anomura have been re-spirited. Thanks to the assistance of 

 Mr. A. 0. Walker, Prof. Gruvel and Dr. Budde-Lund, nearly 

 all the Crustacea obtained during the year have been 

 identified. 



Prototracheata.— All the specimens of Peripatus obtained 

 during the year, were, before registration, submitted to Prof. 

 Bouvier, of the Jardin des Plantes, to aid him in the prepa- 

 ration of his great Monograph, which will, it is hoped, be 

 published in the course of this year. 



Echinoderma. — The visit of Dr. Mortensen was made the 

 occasion of a revision of the MS. Catalogue of Echinoidea. 

 An interesting exhibition of two Astrophytons apparently 

 in sexual congress has been added to the Gallery. All the 

 Echinoderms obtained during the year have been identified. 



Ver'ines. — In the spring Dr. Willey ceased to work at the 

 Polychaeta on his appointment to the Colombo Museum. On 

 leaving the Museum he handed in the following report : — 



" I commenced work upon the Polychaeta in the National 

 collection on October I7th, 1899, directing my attention at 

 first to the Eunicidce, then to the Neveidce, followed by 

 Polynoidoi and other families. 



'•' The general idea was to accumulate a series of prepa- 

 rations, not only for current use, but to be laid by for future 

 reference. Such a series, if carefully selected and reliably 

 labelled, cannot fail to have a certain value, although the 

 difiiculties in the way of a successful definition oi species of 

 soft-bodied worms cannot be exaggerated.
