Conchology. — Mr. W. Denison Roebuck writes : — 
The work of the Conchological Section was done by its 
President, Mr. W. Cash, of Halifax, its Secretary, Mr. Greevz 
Fysher, and by Mr. Vincent Corbett, of Doncaster, while Mr. 
W. Falconer brought a few specimens. Mr. Cash’s observa- 
tions were all made by the Nidd banks close to, above and 
below Knaresborough. He found Helicigona arbusiorum, H. 
nemoralis, Hyalinia cellaria, all in abundance, a few H. 
hortensis, H. aspersa, Zua lubrica, Hygromia rufescens, a 
couple of Pupa cylindracea, and single examples of Hyalinia 
crystallina and H. nitidula. 
Mr. Fysher found, in a timber yard at Scriven Park, a few 
small Arion subfuscus, a few juvenile Limax maximus var. 
jasciata, and Agriolimax agrestis, as well as a few each of 
Vitrina pellucida, Pyramidula rotundata, Hyalinia cellaria, 
H. alliaria and one H. crystallina, and on the south bank of 
the Nidd near Birkham Wood were a few Ancylus fluviatilis, 
and numerous Helicella cantiana. Mr. Corbett in the same 
localities obtained Limncea peregra, H. cantiana, H. hortensis, 
Sphcerium corneum, Clausilia laminata and Limax maximus 
var. jasciata. Mr. W. Falconer, in Birkham Wood, found 
Clausilia bidentata and Zua lubrica, and at Grimbald Crag, 
P. rotundata and several Hygromia hispida.
