Entomological Research Committee. 

 Assistance in the determination of species and in other- 

 ways has been given by the members of the Staff to the 

 Scientific Secretary of the Entomological Research Committee 

 of the Colonial Office during the past year. When the work 

 of this Committee had been well started and in progress for 

 some time, it was found that the room originally provided for 

 the accommodation of the Secretary was no longer adequate 

 for the purpose. Two somewhat larger rooms, instead of this 

 one, have now been given over for the use of the Secretary and 

 Assistants. From the list of additions to the collection, it will 

 be seen that the Museum has already benefited largely by its 

 co-operation with the Research Committee ; and it is anticipated 

 that the benefits will become increasingly great as the work 

 of the Committee progresses. 



Prototracheata. 



The exhibited specimens of Peripatus have been placed in a 

 -special wall-case ; and in spite of the increasing congestion of 

 specimens in the Spirit-building, the study collection has been 

 re-arranged. The MS. catalogue of the specimens has been 

 ^completed. 



A. Guide which refers partly to the Prototracheata 

 ifOnychophora) is noticed below, in the succeeding Section. 



Myriopoda and Arachnida. 



Nearly all the unnamed Scorpions and Pedipalpi have been 

 determined, and the species which are new, or otherwise of 

 interest, have been noted. 



A large collection of Arachnida from the Seychelles has 

 been worked out and incorporated in the collection ; the report 

 on this collection is ready for publication. 



The undetermined specimens of the sub-order Palpatores 

 have been sent to Dr. C. Fr. Roewer, of Bremen, who has 

 described and figured many of them in the first part of his 

 monograph. 



The bottles containing the spirit collection of Arachnida 

 have been cleaned and refilled with spirit, and progress has 

 been made with the arrangement of the dry specimens of 

 Arachnida. 



Attention has also been paid to the collection of Myriopoda ; 

 and a number of centipedes and millipedes (chiefly belonging 

 to the family Spirostreptidae) have been determined. 



A Guide to the Crustacea, Arachnida, Onychophora, and 

 Myriopoda, exhibited in the Department of Zoology, was 

 published during 1910. 



Crustacea and Pycnogonida. 

 Some important additions have been made to the exhibited 

 series of Crustacea, including a fine specimen of the large
