_ 4.—FROM SELBY TO CAMBLESFORTH AND GOWDALL FOR 
ae _ LIMNZ4GA GLABRA, 
By an early train on Saturday morning, 14th April 1887, 
arrived at Selby, and at once made my way to the canal, 
_ which I had found on previous visits to be a prolific hunting 
i ground for mud-loving mollusks. This morning, however, 
_ Iwas afraid was going to prove a blank, as the weather was 
_ cold, with the wind blowing from the east, the quarter most 
dreaded by the field naturalist. 1 searched for a considerable 
time, but was only rewarded by two or three specimens of 
Limnea peregra. On former visits to this canal I have obtained, 
_ buried in the mud and at the roots of sedges and other mud- 
: oving plants, Spheri corneum, Unio tumidus, Anodonta 
_ “gnea, Paludina vivipara, Bythinia tentaculata, B. leachit, and 
Valvata cristata, the latter very common. ifferent parts of 
the canal had produced Planorbis fontanus, P. albus, P. vortex, 
: : +. carinatus, P. umbilicatus, Physa fontinalts, Limnea ora, 
 £. auricularia, L. stacnalis s, and Z. fruncatula.

id L. truncatula. 1 searched each pond and ditch as I went 
along towards Camblesforth ; at or opposite to a place called _ 
Marshallshaw, a little to the north-east of Camblesforth, I made 
‘0 the aquatic mollusca in the ditch I searched among the moss 
: on’ the bank-side, but only found Zonites fulvus and Cochlicopa 
_lubrica, only single specimens of the former, and it is a curious 
zrcumstance respecting my experience of this shell that I pis 
1899.
