86 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



fifteen families are catalogued and beautifully arranged in 

 thirteen cabinets, and that the British series can probably be 

 opened to the public in the present year. 



We proceed now to give a more detailed account of the work 

 done in, and of the additions made to, the several collections 

 of this Department. 



I.— Arrangement. 



1. Additions to the collections of Mammalia have been 

 entered in the catalogues as soon as they were examined and 

 named. The arrangement of the order Ungulata has been 

 completed, and the Hyracoidea have been taken in hand and 

 thoroughly examined. Manuscript lists of these orders have 

 been completed. 



2. In the study-collection of Bird-skins the arrangement 

 proceeds with the progress of the volumes of the Catalogue in 

 course of preparation. But, in addition, all specimens received 

 since the publication of volumes 5, 7, and 8 of the " Catalogue " 

 have been incorporated in the general collection, and the 

 whole of the series treated of in those volumes has been re- 

 arranged in glass-topped boxes and labelled in accordance 

 with the nomenclature of the " Catalogue." 



3. All additions to the collections of Reptiles and Fishefe 

 have been incorporated and entered in the printed catalogues 

 as soon as the specimens were examined and named. Further 

 progress has been made with the arrangement of the collection 

 of Snakes. 



4. In the Mollusca the rearrangement of the general col- 

 lection of Land Shells has been commenced ; a very large col- 

 lection of Marine Shells from Aden has been worked out and 

 incorporated, and in connection with this work many allied 

 species and, in some instances, the entire genera have been 

 studied and the nomenclature determined. The Land Shells 

 of Barbados, the Unionidoi of South Africa, and the Bulimi 

 of the Galapagos Islands have been worked out, and selections 

 from the large collections made by Mr. J. J. Walker and Dr. 

 Hungerford have been mounted and incorporated. Lastly, a 

 number of new species from the " Challenger " Collection have 

 been described. 



5. Crustacea, Myriopoda, and Arachnida. The Assistant 

 in charge of these collections is still engaged in the examina- 

 tion and determination of the Myriopoda. Of this order 

 the whole of GhiUypoda are now named and catalogued. Ad- 

 ditions to the collection of Scorpions from the Malay Archi- 

 pelago and other parts of the East Indies have been examined 

 and incorporated.
