as a. rule, found only scattered “cays of it, rarely more than : 
two or three in a locality. e only exception I can call to 
mind at this time is finding it many years ago very common : 
near to Seacroft Hall. Having left the ditch and passed © 
through Camblesforth I came to a small, shallow, grass-grown — 
pond situated in a widening of the road at a place where two 
or three footpaths diverge. The pond is invariably dried up in q 
summer time. I had searched this place two or three times 
before and have obtained examples of Planorbis fontanus, — 
P. sptrorbis, Limnea peregra, and L. glabra. Leaving these — 
I next came to the large pond at Carleton Towers. Here I ~ 
enlisted the sympathy and help of a farmer who was occupier of : 
the land which surrounds that part of the pond which is cut off : 
from the park. Learning from me that I wished to go some 
distance from the margin, where there was an abundance of the 
broad-leaved pondweed (Potamogeton natans), he took me to 
a somewhat large raft which was floating on the water, but 
I soon found that whatever else we were, we neither of us were 
experts with that kind of craft, as we were continually getting 
both to one end, and so submerging it until the water was 
running over the tops of our oe and after all we were 
scarcely adequately rewarded for our exertions and discomfort. _ 
Mates albus, P. umbilicatus, Pros Sontinalts, mtn peregra, 
L. palustris being all we obtained, and those few species — 
were only represented by one or two gerne tag of each. . Our 7 
management of the raft did not induce any desire on my part to” 
stay long on the pond, and I was heartily glad to get away | 
before making a still closer acquaintance with it. I next tried | 
a ditch at a place called the Dumps, which yielded one or two 
examples each of Planorbis contortus and Physa hypnorum. 
Leaving here I crossed the river Aire by the bridge to Snaith; 
passing through part of the town I turned to the right, and on 
a hedge-bank at Pickhill Bank I found Zonztes cellarius and 
flelix arbustorum. Still bearing to the right towards a place 
called Gowdall, 1 came to a small plot of undrained land, most — 
“Saeed a piece of a former common, and after searching for — 
me time I found examples of Planorbis spirorbis and Limnea — 
hn, both being represented by few and very impoverished- 
looking examples. Still keeping westwards I passed through 
Hensall, only adding Limnea peregra from a ditch by the road, 
and so arrived at the station, where I took the train home, and 
thus concluded another ramble which, though unpromising at 
the beginning, ended very successfully, in the addition of two — 
more habitats fox this local shell.
