THE YORKSHIRE NATURALISTS’ UNION AT AYSGARTH. 225 
In the absence of the officers of the Conchological Section, the 
report on the day’s proceedings was given by Mr. T. A. Lofthouse, 
of Middlesbrough, by whom and Messrs. W. Denison Roebuck, 
F.L.S., and Edward Chapman, assisted by members of the other 
sections, who brought shells for identification, most of the work had 
been done. The section was not, however, by any means sufficiently 
represented to admit of the thorough examination of a district of 
such a varied character as Aysgarth presents, and the dryness of the 
weather further militated against conchological work. The total 
number of mollusca obtained was 31, comprising six slugs, three 
freshwater and 22 land shells. Of these no less than to were 
additional records to the published lists for the district. One of the 
additions was P/anorbis albus, found in the stagnant. pools or old 
river-channels in the Strands pasture, near Carperby. Other four 
were slugs, viz., Arion subfuscus and Limax marginatus (= arborum) 
from Strands pasture, and A. minimus and A. circumscriptus from 
_Carperby. The remaining five were land shells, viz.. Zyavinia ive 
(with var. margaritacea), I. fulva, Cochlicopa lubrica, and Carychiu: 
minimum, all found in the vicinity of Aysgarth Falls, and Helix 
nemoraiis found on the hills above Hawbank Woods. In addition 
to these Helix cricetorum was found in several fresh ogee: near 
Carperby. The other species observed were Arvo: , Helix 
hortensis, and Balea perversa at Carperby, Vitrina gies and 
Clausifia rugosa at Aysgarth Falls, He/tx /apicida common near 
_Redmire, Hyalinia celloria and Pupa cylindracea at Aysgarth, Helix 
rupestris common on _ limestone walls throughout the district, 
i. arbustorum and var. flavescens, H. rufescens and H7. hispida about 
Carperby and Aysgarth, H. sericea common on nettles near Carperby 
and also at the Falls, Agriolimax agrestis, Hyalinia alliaria, 
ff. nitidula, Helix rotundata, and Succinea putris throughout, and 
Limnea peregra i and Ancylus fuviatilis i in the river. 
oe report was given by the President, 
Mr James H. ‘Rowiree ‘who writes that the following members _ 
of the section were also present :—Mr. Walter F. Baker rata 
Mr. M. L. Thompson, Mr. W. Hewett, and Mr. E. G. Pot 3 
The luxuriantly wooded district and the remarkably meas 
_ character of the dale gave promise of great possibilities, which were 
hardly realised during the necessarily limited time available for 
investigation. Mr. W. Hewett and Mr. E. G. Potter, both of York, 
_ who had been staying some days in the district, sugared about sixty 
trees near Redmire on the zoth, but owing to the rain which fell 
unceasingly, both whilst sugaring and when visiting them after dark, 
the results were nil. a these unfavourable ———-
