Myriopoda and Arachnida.* 



The accessions received during the year, which include large 

 collections from Japan and Algeria, have been registered and 

 incorporated. Reports dealing with several of the more 

 important accessions have been published. 



Dr. C. Fr. Roewer, of Bremen, has determined the Harvest- 

 men of the sub-family Phalangiinas in the collection and has 

 described a number of new forms in the second part of his 

 monograph. 



Fresh camphor has been placed in all the drawers and store 

 boxes containing the dry collections of Arachnida and 

 Myriopoda. 



A number of Myriopods, chiefly of the family Scolopendridse, 

 have been determined. 



Crustacea and Pycnogonida. 



In the exhibited series of Crustacea the large crab Paro- 

 TTiola cuvieri has been repainted from a coloured sketch of a 

 fresh specimen ; a spirit preparation of a Hermit-crab and its 

 commensals has been added ; and thirty-one labels have been 

 printed. In the Crustacea Room, numbers have been affixed to 

 all the shelves of the cupboards containing the spirit collection, 

 and some work has been done in re-pinning and repairing the 

 specimens in the dry collection. A beginning has been made 

 with a revision of the MS. catalogue of Brachyura. 



The final instalment of Canon Norman's collection has been 

 received and forms the most important addition made to the 

 collection for many years. Until the registration of the 

 specimens has been completed, their number cannot be stated 

 exactly, but it is estimated at not less than 35,000. The 

 incorporation of these with the general collection is, of coui'se, 

 out of the question for the present ; and even their safe custody 

 is a matter of constant anxiety under existing conditions. The 

 drawers of the cabinets have been numbered and an index to 

 the genera has been prepared to facilitate reference to the 

 collection. 



A large collection of Cumacea belonging to the United 

 States National Museum has been worked out and a valuable 

 series of duplicates selected from it. Collections from New 

 Guinea, Christmas Island, Vancouver Island, and from 

 telegraph cables in Eastern Seas have also been examined.

The rearrangement of the dried study collection of Echino- 

 derms has taken much longer than was expected, and is not
