244 THE ZOOLOGIST. 
Zonites radiatulus—Not a very widely-spread species, but 
common round York, particularly among the roots of the grass on 
the lawn at 20, Bootham, and at certain spots in the Far Wood at 
Askbam Bog. Found also in the woods about Strensall, Knaves- 
mire, and Nova Scotia Plantation. 
Zonites nitidus—Rare. Banks of Foss (H.) I have found it 
at Bishopthorpe and along the side of a small ditch upon Clifton 
Ings. Bootham collectors obtained it in 1853 at Hobmoor and 
near the Water-works. Ouse rejectamenta (H.) 
Zonites excavatus.—Nowhere common, and rare in the York 
district. I have obtained it in Nova Scotia Wood, and possess a 
specimen from some other locality near the city. 
Zonites crystallinus.—General. Abounds beside the small 
ditches on Bishopthorpe and Clifton Ings, in the Far Wood at 
Askham, one wood at Longwith, &e. As might be expected from 
its living on the banks, it is very plentiful in the rejectamenta of 
the Ouse. 
Zonites fulvus.—Very well distributed, but far from being 
common. I have found it at Linton-up-Ouse, Hobmoor, and 
Clifton, and in Overton, Skelton, Stockton, Strensall, Castle 
Howard, Askham and Longwith Woods. 
Helix aculeataa—Rare. I have never found it myself, but 
Mr. Backhouse says, “I have found this on the edge of Hobmoor, 
and have seen it both from Longwith and Queen Elizabeth's 
Walk;” and Mrs. Corder, of Chelmsford, has some from here. 
Buttercrambe Moor (H.) Among moss in Nova Scotia Wood (R.) 
Castle Howard (H.) 
Helix aspersa.— Far too common for gardeners. I have been 
struck with the number of dead shells to be found in holes in the 
Castle and City walls, and even embedded in the mortar itself. 
Var. tenwis.—Common. 
Helix nemoralis.—Not nearly so common as might be expected. 
I have found a few at Askham, and many on the nettles and other 
large plants beside the railway-line crossing Hobmoor. One from 
this locality was yellowish in colour, with bands almost white. 
A yellowish white variety was collected about thirty years ago on 
a hedge-bank at Fulford by a relative of mine (R.) Its habit does 
not seem to lead it to ascend hedges to nearly the same height as 
H. hortensis, though I once got some fine specimens in such a situa- 
tion at Copmanthorpe. This species seems to be upon the inerease,
