114 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



the dried collection, and the stagnation in the incorporation 

 of the always-increasing spirit collection owing to the con- 

 gested state of the cabinets is a serious interference to 

 work. 



Most of the specimens obtained during the year have been 

 determined. 



Vermes. — Most of the Land Planarians obtained have been 

 determined by Prof. Graff, and Dr. von Linstow has kindly 

 given assistance with the Nematodes. 



A few additions, including a Dog's heart infested with 

 Filaria iinmitis, have been made to the exhibited series, 

 and the collection generally is in good order. 



Eckinoderina. — The exhibited collection of Echinoidea has 

 been arranged, and fresh explanatory labels prepared, and a 

 new series of specimens illustrating the Morphology of this 

 group has been commenced. 



The task of incorporating dried specimens has been facili- 

 tated by the addition of a cupboard for the reception of 

 exceptionally large forms, of which there are many in the 

 collection. 



Anthozoa. — The re-arrangement consequent upon the 

 change in the uses of the Coral Gallery has not yet been 

 completed, as the new cases required have not been delivered. 

 An addition to the exhibition area has been obtained by 

 opening up a closed gallery of communication very suitable 

 for large blocks of coral. 



A dried collection of large specimens of Alcyonaria has 

 been thoroughly cleaned. 



Porifera. — The chief work of the year has been the com- 

 pletion of a manuscript Catalogue of the spirit collection of 

 Sponges, the labelling and conservation of the specimens at 

 the same time receiving attention. 



A collection of Sponges, comprising fifty-six specimens, 

 brought by Mr. C. W. Andrews from Christmas Island, has 

 been worked out and described. 



The magnificent collection of Hexactinellid Sponges from 

 Japan has now been mounted and exhibited in the Hexacti- 

 nellid case, which has been entirely re-arranged, the old 

 specimens being re-mounted. A small collection of Calca- 

 reous Sponges has also been exhibited in the Coral 

 Gallery. 



II. — Duplicates and Exchanges.

 have been selected by representatives of the under-mentioned 

 Institutions, and have been presented on the understanding 

 that the first opportunity will be taken of making a suitable 

 return : —
