With regard to the Adder, it may be mentioned that Mr. Robert 
Clark, of Pickering, captured one a few days previous to the meeting, 
of very unusual size, measuring nearly four feet in length. 
The Conchological Section, too, was entirely unrepresented by 
its officers, and the only members of the section present and making 
observations were Messrs. J. and W. Hawkins, of York, and Mr. W. 
Denison Roebuck, F.L.S., of Leeds. The results of their investiga- 
tions were, however, but small, the weather being much too fine and 
dry to permit of many molluscs being seen. Messrs. Hawkins noted 
Hyalinia alliaria, Helix aspersa, H. nemoralis, H. hortensis, H. 
arbustorum, H. rufescens, Bulimus obscurus, Clausilia perversa, and 
Limnea peregra. Mr. Roebuck’s observations related chiefly to the 
slugs, of which were found not far from Levisham Station in the 
early morning numerous and variously-coloured examples of Avioxz 
ater, including pale green and yellow ones of small size, as well as 
the typical black form, a few A. subfuscus and A. hortensis, plenty of 
A. minimus, one small Limax maximus, and plenty of Agriolimax 
agrestis under old sleepers. In the ditches near the station Limnea 
peregra existed in great numbers. On the previous day, at Lockton, 
was found an example of He/ix hortensis var. lutea 12345, in company 
with Agriolimax agrestis and Arion ater. Mr. John Braim showed 
the following species which he had collected about Pickering a few 
days before the excursion -— Helix pulchella, H. itala (ericetorum), 
Cochlicopa lubrica, Clausiiia perversa, Cl. laminata, Bythinia 
tentaculata, Spherium corneum, and Sitti pusillum. ee
