REPORT OF THE 
The space thus gained has been utilized for the display 
of the metallic minerals to advantage, even after making the 
necessary insertions. 
In addition a small collection of Pseudomorphs is also 
exhibited. Notwithstanding the smaller space occupied by the 
siliceous minerals, the actual number of specimens has been 
increased by numerous additions, some of them belonging to 
species and varieties hitherto unrepresented in the collection. 
A series of the rocks of Auvergne has been presented to 
the Society by Mr. Grough, and this may possibly form the 
nucleus of a rock collection, which would be a very desirable 
addition in the department of Mineralogy. 
CoNCHOGicAL DEPARTMENT. —A second Cabinet has been 
presented by Mr. Peed for the further accommodation of the 
Foreign Shells. The univalves have now been entirely arranged 
in one large cabinet, and the bivalves will occupy the other. 
Some interesting fresh-water shells from North India have 
been received during the year, collected by Mr. W. H. Cobb, 
who reports that the village ponds in those districts abound 
in the species forwarded. The disastrous effect of the dry 
summer of 1884 and of extended drainage operations upon 
the rich conchological fauna of the neighbourhood of York 
deserves record. The ponds on Strensall Common where 
Limncea stagnalis and Planorhis corners attained such grand 
dimensions are now no more; and it is to be feared that 
one of our York rarities, Limncea glahra, will have become 
very scarce, as the shallow ditches which are its haunt dried 
up in the summer of 1884, and seem never to have recovered 
themselves. 
The Curator regrets that the poverty of the Conchological 
literature in the Library of the Museum renders the specific 
identification of foreign shells almost impossible. 
Entomological Department. —The only additions made 
to this department during the year are a few specimens of 
Mexican Coleoptera presented by J. Backhouse, Esq., Junr.
