110 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



sub-family has been arranged ; and the MS. of Volumes VII. 

 and VIII., containing the Acronyctince has been completed. 



In the Oeometridce the re-arraugement of the Boarmiance 

 has been completed, and portions of the Acidoliance, 

 (EnochromincB, and Orthostixince have been dealt with. The 

 whole of the American types of Geometridoe in Mr. Rothschild's 

 collection, described by Mr. Warren, have been compared 

 with the Museum Collection by Mr. L. B. Prout, and numerous 

 species identified. 



The re-arrangement of the collection of British Lepidoptera 

 has been completed. 



Crustacea. — The arrangement of the exhibited series has 

 been continued, and a large number of spirit and other 

 specimens and some illustrative coloured drawings have been 

 added. The cases illustrating the classification of the lower 

 Malacostraca and the Entomostraca have been practically 

 completed during the year. Specimens of the recently re- 

 discovered British Apus cancrifornbis have been mounted as 

 a special exhibit in the Central Hall. In the Crustacea room 

 some urgently needed space has been gained by fitting an 

 additional shelf in most of the cases containing the spirit 

 collection, and advantage has been taken of the re-arrange- 

 ment involved to label the cases and shelves in a manner 

 more convenient for reference. A large number of the 

 bottles have also been cleaned and refilled. The dry collec- 

 tion of Cirripedes has been transferred to the new cases and 

 arranged in systematic order. Important exchanges have 

 been carried out with the Museums of Paris and Dundee, and 

 a very heavy list of other accessions has been dealt with. 

 Work on the Cumacea has been continued, and on the publi- 

 cation of the first part of a report on Cumacea of the 

 Copenhagen Museum, the collection has been enriched by a 

 valuable set of co-types. The collection of Spiny Lobsters 

 (Palinuridce) has been revised in the light of recent work, 

 and the unnamed material of the family determined. 



Prototracheata, Echinoderma, Vermes, and Anthozoa. — 

 The whole of the spirit collection has been gone through and 

 rearranged, and a new MS. Catalogue of the systematically 

 arranged specimens has been prepared ; this is being indexed, 

 and will greatly facilitate the speedy finding of specimens 

 required for study, but the necessity of increased space for 

 the collection of Invertebrata is rapidly becoming urgent. 



All the specimens of Prototracheata received during the 

 year have been named by Prof. Bouvier, registered, and 

 incorporated. 



All the specimens of Echinoderma received during the 

 year have been named and incorporated ; the systematically 

 arranged and exhibited specimens have been provided with 

 a number, as have also the exhibited Worms.
