iMollusca. — The working out of the important collection of 

 deep-sea Mollusca, obtained by H.M. Indian Survey Steamer 

 " Investigator," commenced during the year 1905, has been 

 completed, and the report published. A manuscript list of 

 the species of Polyplacophora has also been prepared. A 

 large collection of shells made by the late Colonel Surgeon 

 Archer at Singapore and other localities has been examined, 

 and a selection made from it. The important collection of 

 Indian land and fresh-water shells, bequeathed by the late 

 Dr. W. T. Blanford, has been unpacked and partly examined. 

 Numerous species of land shells forming part of the exhibited 

 series have been remounted on fresh tablets and furnished 

 with printed labels. The collection contained in spirit has 

 been attended to, and fresh spirit supplied where necessary. 



Arachnida and Myriopoda. — The spirit collection of 

 Arachnomorphoe and of Myriopoda has undergone re- 

 arrangement, and part of the unnamed material has been 

 sorted into families. The Scorpions and Pedipalpi have been 

 worked out. Many Ticks received were sent before registra- 

 tion to Professor Neumann for determination, and a report, 

 based on these examinations, will appear shortly. Herr With 

 has continued his work on the Chelonethi belonging to the 

 Museum, and an additional report dealing with the South 

 American forms is now in course of publication. 



Insecta. — The task of transferring the portion of the Fry 

 Collection of Coleoptera contained in cabinets was finished in 

 the spring, and the cabinets returned to the executors. The 

 greater part of the specimens so transferred, including the 

 whole of the Lamellicornia and Longicornia, is now incor- 

 porated in the General Collection. 



A second portion of the Sharp Collection of Coleoptera 

 has been acquired, comprising the Geodephaga, Clavicornia, 

 Palpicornia, Heteromera.. &c., about 50,000 specimens in all. 

 The Central American specimens of water-beetles and certain 

 Clavicorn families, including a large number of types, have 

 been labelled and incorporated in the Central American 

 Collection. 



Some further progress has been made with the incor- 

 "poration of the Janson Collection of Elateridce. The un- 

 determined American Cleridce have been worked out by 

 Herr Schenkling, of the German Entomological National 

 Museum, and the Oriental specimens of the' family have been 

 sent to him for the same purpose. All the Museum repre- 

 sentatives of the genera Ichthyurus and Sciobius have been 

 determined or described by Dr. R. Gestro and Mr. Guy 

 Marshall, respectively, and have since been completely 

 re-arranged. 



In connection with the preparation of the Second Volume 

 of the Catalogue of Orthoptera the later groups of Phasgo- 

 nuridcB have been re-arranged or revised in accordance with it.
