YORKSHIRE NATURALISTS IN MID-RIBBLESDALE. 9 
the Union excursion in 1881, was productive of so many species 
of aquatic mollusca, and therefore none of these were observed. 
f slugs 6 species and of land shells 19 were collected, making 
a total for the day of 25. Most of them—slugs especially—were 
only found sparingly, a natural consequence of the dryness of the 
summer as well as of the weather on the day itself. A particularly 
productive collecting-ground was afforded by an old and shapeless ruin 
about midway between Gisburn and Sawley. Here, and here only, 
were found Helix granulata (=sericea), H. nemoralis, H. hortensis, 
Clausilia laminata, and Bulimus obscurus, while both here and at 
various points along the Ribble bank occurred C/. ferversa, Pupa 
cylindracea (umbilicata), Azeca tridens, Cochlicopa lubrica, Carychium 
minimum, Helix hispida var. hispidosa, H. rotundata, H. rufescens 
(this in its usual profusion), Ayal/inia cellaria, Hf. crystallina, 
Hf. alliaria, H. nittdula, H. nitida, Vitrina pellucida, Arion ater, 
A. hortensis, A. subfuscus, A. ctrcumscriptus, Agriolimax agrestts, 
and Limax marginatus (arborum). 
The entomologists were not able to report a very successful day, 
meteorological conditions being adverse. Few insects were seen on 
n ex 
a happy hunting-ground for coleopterists, proved quite the reverse. 
Special mention might be made of Si/pha atrata, which was taken 
under a stone. Mr. S. L. Mosley, F.E.S., spent the day in 
searching for Galls, with the — results :— 
Euura pentandre. Rhodites Cecidomyia ulmariz. 
Cynips kollari. Rhodites eglantetic. Cecidomyia urticze. 
Andricus gemme. Cecidomyia taxi. Cecidomyia violz. 
With regard to the last named (Cecidomyia viole) it should be added 
that the flies have since bred, and an important feature of this 
discovery is that Mr. Mosley has been unable to find any previous 
record of its having bred in — 
Amongst the botanists were Mr. Chas. Crossland, of Halifax, 
and Mr. T. F. Ward, of si (RSG The plants met with were 
quite what might have been expected and call for no special notice, 
excepting that Mr. Crossland was somewhat surprised to see the 
Purple Loose-strife. About 160 flowering plants were noticed near 
Sawley Abbey, amongst which were the following :— 
Thalictrum flexuosum. Geranium sylvaticum. 
Cardamine amara. Geranium lucidum. 
Stellaria nemorum, Impatiens noli-me-tangere. 
Hypericum androsemum. Alchemilla montana. 
icum dubium. ‘ Sanguisorba officinalis.
