426 THE ZOOLOGIST. 
H. nemoralis. The Wood Snail.—This species occurs in the 
Pontefract district in considerable abundance. Neither Gwyn 
Jeffreys nor Tate gives any account of its feeding habits. 
Although I have seen it hundreds of times on nettles and other 
plants, I have never actually observed it feeding on the plants. 
I suspect that it feeds on decayed vegetable matter, and, like 
others of the genus, may be much more carnivorous than is 
supposed. The varieties from Pontefract are as follows :— 
Var. major, Fer.— Bands 12345 and others. 
Var. minor, Moq.— Greatest diameter three-fourths of an inch, 
altitude seven-sixteenths. Shell red, with one black band on 
the periphery and a white line beneath it. 
Var. roseo-labiata, Taylor.—Shell pink, with a broad red band 
on the periphery, and a white line beneath it. 
Var. albolabiata, Yon Martius.—Two specimens; yellow, with 
translucent bands. Rare. 
Var. bimarginata, Moq.—Common; variously banded. 
Var. libellula, Risso.—Common ; some nearly white. 
Var. rubella, Moq.—Many of a light cherry-red colour, finely 
polished. The bandings are mostly 12345 and 00300. 
I have one with 00305. Some are exceedingly thin, with 
conical spire. 
Var. castanea, Mogq., and var. olivacea, Gassies. — Various 
intermediate colours of these occur. Most that I have seen are 
inclined to olive, and bandless. I have one specimen which is 
very glossy and thin, of a greenish purple colour, with a white 
line in the suture of all the whorls. A dark brown band encircles 
the periphery, with a faint white line beneath it. Lip dark 
brown; inside of the shell purple. 
Var. hyalozonata, Taylor.—Not yet recognised. 
The band-varieties 00300 and 02345 are frequent. Others 
I have found with interrupted bands. The animal of one of 
the chestnut-coloured specimens was creamy-white, with a sub- 
cutaneous bluish tinge. Another (with chestnut shell) was slaty- 
blue, with a white median line. Another (shell yellow) was 
greenish brown, with a yellowish white, narrow dorsal median line. 
Another was a uniform light straw-colour. The animals seem to 
vary in colour nearly as much as the shell. Mr. Hudson tells 
me that the animal varies in nearly all shades from black to 
white. It is scarcely necessary to point out that the bands do
