104 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



The collections made during the year by Mr. Loat for the 

 Nile Fish Survey have been the subject of a special report to 

 the Trustees. The series of African Fishes has been further 

 enlarged by extensive collections from the Congo and Ubangi, 

 the Gambia., the Niger, and the Gaboon. 



A commencement has been made with a new series of 

 Freshwater British Fishes, mounted according to modern 

 methods. 



Mollusca. — The very large collection of land and freshwater 

 Mollusca from Central America, presented by F. D. Godman, 

 Esq., consisting of about 4,500 specimens, has been compared 

 with the published report upon it by Dr. E. von Martens and 

 the typical set selected for the collection. The mounting, 

 registration, and incorporation of this and the numerous 

 .other additions in Mollusca have occupied much of the time 

 of the staff in charge of this part of the collection. 



The Mollusca obtained in the Antarctic Region by the 

 ."Southern Cross" have been studied and described. A 

 historical account of the general collection from the com- 

 mencement of its formation up to the present time has been 

 prepared, and a report has been written upon the land and 

 freshwater shells collected in the Maldive Islands by Mr. J. 

 Stanley Gardiner. The exhibited and study collection of 

 AchoMnellidce has been remounted and the species arranged 

 according to the most recent monograph by Mr. E. R. Sykes. 

 The exhibition series of Helicoid land-shells has also been 

 rearranged. A typical exhibition collection of British shells 

 iias been placed in six small cases in the shell-gallery and the 

 study series arranged in drawers of the adjacent cabinets. 

 The collection of Pearl-Oysters has been studied and named 

 by Mr. H. Lyster Jameson, and a set of specimens v/ith their* 

 trade-names and values has been placed on exhibition. New 

 locks have been applied to the cases containing the most 

 valuable specimens, and the shells exhibited in these cases 

 have all been cleaned. The remaining portion of the collec- 

 tion preserved in alcohol has been re-spirited. 



Crustacea: — Further additions have been made to the series 

 of specimens exhibited under natural conditions, and to the 

 morphological systematic series. Special attention may be 

 called to the series illustrating the ecdyses or moultings of 

 Crabs. 



A room having been set apart for the spirit collection, one 

 side ha.'i boen fitted with commodious cupboords into which 

 the collection of Brachyura e^nd Anoyvuva, has been removed. 

 The congestion so frequently complained of has disappeared, 

 and there is room for the collection at its normal growth for 

 at least ten years. Two'new cabinets of dried Crustacea have 

 been arranged;, and most of the specimens obtained during 

 the year have been determined.
