122 accounts, etc., of the british museum. 



Peripatus. 



The collection, which is fully determined, has been re- 

 arranged, and is now more accessible. 



Crustacea and Pycnogonida. 



In the exhibited series of Crustacea a coloured drawing from 

 living British specimens of the Fairy Shrimp {Chirocephalus 

 diaphanus) has been prepared and placed in the Gallery. 



In the Crustacea Room the whole of the spirit collection 

 has been overhauled, and the bottles, about ] 3,500 in number, 

 have been cleaned and refilled. Of the Norman collection, 

 received in 1911, 19,177 specimens have been registered, a 

 large number of tubes refilled, and faulty corks replaced. The 

 Budde-Lund collection of Woodlice, received during the year, 

 has been placed in bottles, and arranged in systematic order, 

 in preparation for labelling and registration. A large number 

 of other accessions have been registered and incorporated. 



Echinoderma.* 



The rearrangement of the dried collection of Echinoderms, 

 by which space has, it is hoped, been gained iot the systematic 

 incorporation of accessions for some years, has been completed, 

 and an index ha,s been made to the drawers. Unfortunately 

 there is not now the space to arrange accessions to the spirit- 

 collection systematically ; and much trouble must be expected 

 in finding specimens asked for by students. Most of the 

 specimens obtained during the year have been determined, and 

 all have been incorporated. 



Worms. 



Dr. J. H. Ash worth's " Catalogue of the Arenicolidse" has 

 been revised and passed through the press. The MS. list of 

 Gephyrea has been added to, and brought up to date. A MS. 

 list of the species of Chsetognatha has been prepared, but the 

 specimens in the collection have not yet been catalogued : 

 attention has been given to the collection of Nematode Worms, 

 and the nomenclature is gradually being brought up to date. 



A specimen of " measly pork " better than that at present 

 exhibited has been mounted, and will be shown as soon as a 

 descriptive label has been prepared. 



As it was found that long worms in tubes suff'ered from 

 exposure to dirt, a closed cabinet has been devised, which affords 

 room for additions. 



The systematic rearrangement of the collection of micro- 

 scopic slides has been continued. 



* The Assistant in charge of this and other groups has edited the 

 Reports on the National Antarctic (" Discovery ") Expedition, 1901-4, the 

 sixth and last volume of which has been published during the year.
