YORKSHIRE NATURALISTS’ UNION AT GRASSINGTON. 269 
Clausilia rugosa, before again mounting the conveyance. Then being 
rapidly driven towards their destination they could not but admire 
the beautiful flowers of Geranium sylvaticum by the road-sides. 
Directly the Wharfe was reached and crossed the conveyance was 
left for good, and the party followed the footpath along the north 
bank to Ghaistrills. Here, in a water-trough were obtained examples 
of Limnea peregra, and a single specimen of He/ix laficida en- 
sconced in a corner of the trough a few inches above the water. 
little result. The search was, however, steadily continued as the way 
was made to the foot of Dewbottom Scar. Here there was a pretty stiff 
and awkward climb up the steep slope and the nearly perpendicular 
rocks of the summit, but this being reached the sight of the abundant 
blossoms of Rosa mollis was a rich reward. On the summit some 
time was spent in searching amongst the only damp leaves to be 
found. Here were obtained dead examples of Vitrina pellucida (each 
excursion this year has confirmed as a fact that winter and early 
spring is the time to collect this mollusc in a living state), Zonttes 
cellarius, Z. nitidulus, Z. purus, Z. Julvus, Z. crystallinus, Z. glaber, 
Z. alliarius, Z. radiatulus, Bulimus obscurus, Pupa umbilicata, 
one Vertigo edentula, Clausilia rugosa, Cl. laminata, several Azeca 
tridens, a few Zua lubrica, and a dead Carychium minimum. On 
this spot being left the wood was traversed by way of its bare and 
sterile summit, enlivened however by the chaste flowers of the 
Mealy Primrose, and passing alongside Gregory Scar, the great 
profusion of the Globe-flower was noticed in certain parts of the 
woods. Grassington was reached soon after this, when Mr. A. H 
Pawson laid before the Section examples of Helix nemoralis, 
Hi. arbustorum, Succinea putris and Limnea peregra, which he had 
collected the previous evening, and Mr. Riley Fortune, F.Z.S., 
showed specimens of Ancylus fluviatilis. At the sectional meeting, 
Mr, William Cash, F.L.S., of Halifax, was voted to the chair, and 
afterwards reported the, results to the general meeting. After the 
meetings were over, Messrs. Pawson, Roebuck, and R. Rosenstock, 
B.A., who were remaining behind for the week end, took the 
opportunity to go down the Burnsall footpath to look for and confirm 
the reported occurrence of Cyclostoma elegans. This was soon done, 
numerous dead examples being found on banks close to the footpath 
and river in Lythe woods, about a mile and a half from Grassington, 
and with them numbers of other dead shells, including plenty of 
Helix ericetorum. This walk was continued to Hebden, where a 
mill-dam yielded numerous Zimn@a peregra and Pisidium fontinale.
