MOLLUSCA IN THE NEIGHBOURHOOD OF PONTEFRACT. 427 
not commence on the first whorl, but appear sometimes on the 
second and sometimes on the third, and gradually increase in 
number. Whatever colour the shell may be, the bands are nearly 
always brown of different shades. Sometimes a white band 
occurs where the brown bands are all fused into one, and some- 
times translucent bands appear on yellow shells. Mr. Wilcock, 
of Wakefield, has two examples of nemoralis which have a tooth- 
like projection on the pillar-lip. One of this kind might have 
resulted from accident, but it is singular that two should be 
found alike. 
H. hortensis. The Wood Snail.—I have not yet observed 
this form on the eastern side of Pontefract, though it occurs on 
the western side. 
H. arbustorum. The Shrub Snail.— Occurs in numbers on 
banks in Bondgate, within two minutes’ walk of the ruined 
church at Pontefract; also at Monkhill, a little to the north. I 
have never seen this species in gardens, and seldom in woods 
about here. 
Var. alpestris, Ziegl.—Forms agreeing with the description of 
alpestris occur; but if this variety inhabits low lands as well as 
high lands the name alpestris is misleading. 
Var. conoidea, Westerl.—Conoid forms occur numerously, both 
large and small. I do not know what difference there is between 
alpestris and the smaller examples of conoidea. 
Var. marmorata, Taylor.—In Ferrybridge Lane, but rare. 
Var. cincta, Taylor. — A few in a nettle-bed about two miles 
from Pontefract; more numerous at the same place in 1884, 
Occurs also at Ferrybridge. 
Var. flavescens, Moq.—Is said to occur, but I have not seen it. 
H. cantiana. The Kentish Snail.—Occurs in thousands in 
Ferrybridge Lane, about two miles to the east of Pontefract. 
The shell is white when young, but some of the adults may be 
safely classed under the variety albida, Taylor. The animal here 
is finely tuberculated, of a light slaty-blue colour, with the sole 
of the foot yellowish white. Large numbers of eggs of this 
species and of H.nemoralis were deposited in a collecting canister 
on September 11th, 1884. I have noticed depressed and conical 
forms, but this species seems to vary very little. Scalariform 
examples are very rare. About Pontefract H. cantiana is to be 
found in ditches in great numbers, mostly hanging in the day-
