LAND AND FRESH-WATER SHELLS. 243 
Fam. HELIcIDm. 
Succinea putris.—Abundant and very fine on Clifton Ings, also 
at Bishopthorpe, beside the Foss, &c. Mr. Hey says, ‘‘ Succineas 
seem to be very fine about here. My largest specimen is from 
Skelton Lane.” Mr. Jeffreys remarks that they hybernate very 
early, and I could not see one specimen upon Clifton Ings on 
September 27th, 1877, though some were found beside the Foss 
as late as October 6th. 
Succinea elegans.—Common at Hobmoor, Askham and other 
places. Banks of Foss (H.) 
Succinea oblonga.—In 1877 1 was carefully searching some 
drift-sand and other rubbish from the banks of the River 
Foss at Yearsley Lock, when I discovered an exceedingly fine, 
but unfortunately rather broken and very bleached, specimen of 
this rare shell. Mr. J. W. Taylor, of the Yorkshire Naturalists’ 
Union, at first doubted whether my naming of it was correct, but 
upon my sending him the specimen he admitted that it was un- 
doubtedly S. oblonga, but he considered it as evidently fossil. It 
may be so, but I see no reason for considering it anything else than 
a bleached and weather-worn specimen. He also exhibited it, asa 
shell new to Yorkshire, before the Leeds Conchological Society. 
Vitrina pellucida.—Very general, but not abundant. Found 
along the Foss, at Hobmoor, Askham, Castle Howard, Knavesmire, 
Bishopthorpe, Clifton, &c. I got a number of dead specimens in 
the “Far Wood” at Askham in March, 1876, and live ones in the 
early part of the following November at various places. The 
creature is very moist and far too big for the shell. 
Zonites cellarius.—Generally distributed. With one exception 
(Z. glaber) we have every species of British Zonites round York. 
Zonites alliarius.— Rare, though well distributed. A few 
are found on artificial rockwork in York. It lives in moist 
woods under moss or dead leaves. Acomb, Skelton, Overton, 
Strensall, Knavesmire, Castle Howard, and Nova Scotia Plantation. 
Also common in Mr. Backhouse’s hothouses at West Bank. Its 
unmistakable smell of garlic at once distinguishes it. 
Zonites nitidulus—Commoner than I have ever seen it else- 
where. 
Zonites purus.—Scarce, but to be got on the sides of the ditches 
upon Clifton Ings, Bishopthorpe, and elsewhere,
