REPORT OF THE 
i 
additions to the collection of minerals are some zeolites, chiefly 
from Faroe, presented by Miss Birley, and some crystals 
obtained from the final diamond washings of the Kimberley 
mine, presented by Major Barstow. Several additions have 
been made to the rock collection—chiefly igneous rocks. 
Report of Conchological Department.— The only 
addition to the collections which the Honorary Curator has 
to report is a small series of Land and Freshwater shells from 
Kashmir. These shells, especially the Fluviatile species, are 
very closely related to, and in some cases identical with, 
British species; affording one among many proofs of the 
Zoological unity of the great Pahearetic Province. 
It is gratifying to observe that Paludinn conteda has been 
met with in several localities in south Yorkshire. This species 
once occurred near Fulford, but has long been extinct in the 
neighbourhood of York, and it was feared that the shell had 
ceased altogether to exist in this country, where it reaches the 
northern limit of its distribution. 
The Honorary Curator, since residing at Ayton, has 
investigated the molluscan fauna of that district. In addition 
to 24 terrestrial species discovered which are common also to 
the York district, 15 others have occurred (not including the 
slugs). The most interesting among these are Helix fused, II. 
sericea , Hyalin a puna, Vertigo pusilla, Cyclodoma elegans , and 
Acme fusca. The river Derwent yields the somewhat scarce 
variety of Limnea auricularia known as acuta. 
Department of Entomology.— The Honorary Curator 
reports that the Allis collection of Lepidoptera, the Hey 
collection of Coleoptera and the collections in general are in 
good order and preservation. 
An excellent economic series of insects, arranged and set 
up by Mr. Mosley, of Huddersfield, has been presented by 
the Honorary Curator. This series consists of insects useful 
or injurious to man; the latter arranged according to the 
substances that they injure. 
In addition to this, a series of preparations has been made 
to serve the ordinary visitor as an introduction to the study
