260 Yorkshire. Naturalists at Settle. 
Mr. H. B. Booth informs me that Mr. G. Bolam visited the 
district during the Union’s excursion, and reported seeing the 
Stonechat. This is a most interesting record, and one which 
the Bradford naturalists have tried to establish for many years. 
It has frequently been reported for the North-West portion, 
but hitherto, so far as I am aware, without success. 
ConcHoLocy.—Mr. Thomas Castle writes:—The sunny 
and dry weather did not favour the Conchologists. The dusty 
condition of the roadside vegetation, due to the abnormal 
motor traffic, and the dry condition of the ground in the 
wooded areas (except in very shady places), also militated 
against record making, so that several species previously found 
in the district were not confirmed on this visit, though additions 
were made. The varied geological formations covering the 
area traversed should, upon persistent search, considerably 
extend the species known for the district. The Giggleswick 
School museum should be enriched by the addition of local 
specimens of land and fresh water shells, as they would also be 
useful as permanent records of the mollusca occurring in the 
district of Settle. 
The land shells noted were :— 
Helix aspersa. Hi. pura. 
H., nemoralts. Bulimus obscurus. 
H., evicetorum. Cochlicopa lubrica. 
Hi. vufescens. Pupa vingens. 
H. votundata. Clausilia vugosa. 
Hi. vupestris. C. dubia. 
Hyalina nitidula. Vitrina pelucida. 
H. cellaria. An undetermined species of Vertigo. 
H. crystallina. 
The freshwater species noted were :— 
Limnea peregra, the long spine form in pond near the 
Victoria Cave; the short spine form in river Ribble ; young 
growth in many smaller ponds and wells, including the Ebbing 
and Flowing Well. 
Limnea truncatula in the river Ribble. 
Ancylus fluviatilis, common, and of good form in river 
Ribble. 
An undetermined species of Pisidiwm was found on Cocket 
Moss. 
HYMENOPTERA.—Mr. R. Butterfield writes :—In spite of 
the sunny weather, an easterly wind proved unfavourable for 
collecting hymenoptera. The social bees and wasps were not 
uncommon, but solitary species were scarce. Of the social 
bees, Bombus soroensis was the most interesting. B. terrestris, 
B. lapidarius and B. hortorum were well distributed. Among 
the wasps, both the species which nest in trees were captured. 
A single example of the rare Audrena lapponica Zett. was 
caught.
