264 Natural History of Middleton-in-Teesdale. 



information of any future worker who might wish to verify the 

 record ; the date, number and sex of the specimen taken to tell 

 the time of adolency or immaturity and the comparative rarity 

 or abundance of the species, together with any further particu- 

 lars as to its habits or life-history and the kind of habitat 

 favoured. It was urged, also, that a good look-out should be 

 kept for definite examples of the way in which spiders are 

 disseminated, and that more attention should be paid to ab- 

 normal specimens, and means taken to preserve them. 



For the Conchological section Mr. T. W. Saunders writes 

 that in a wooded valley which leads to King's Walk and Jack 

 Scar, he found Agriolimax agrestis, with ^'arieties ; Helix rottm- 

 data, Zonites nitidus, and Vitrina pellucida. Close to the stream 

 he came across a colony of Helix arbustorum. Agriolimax agrestis 

 was very abundant, almost every stone turned over yielded 

 several specimens. A little further on were many Helix 

 arbustorum, Avion ater. Helix hortensis, H. hispida, H. nemoralis 

 var. carnea, Cochlicopa htbrica, and a little beyond was Zonites 

 crystallimis, Helix hortensis var. lutea and Bidimus obscurus. 

 In an old disused limestone quarry I got Pupa umbilicata, 

 P. marginata and P. ringens (?) with Bidimus obscurus, Helix 

 hortensis and H. rufescens. 



Amongst some old ruins, I got Zonites cellarius and Z, 

 alliarius. Avion ater was in abundance ; Helix arbustorum 

 was very plentiful, feeding on the grasses. 



On Monday we drove to Lunedale, and in an old quarry I 

 got Carychium minimum, Zonites fulvus, and Helix hortensis 

 and its var. lutea copulating. Further up I got Agriolimax 

 laevis. and Zonites alliarius. Near the stream I got Ancylus 

 fluviatilis and in a pond close by, Pisidium pusillum, which 

 was in abundance. Above the reservoir works in a small pond, 

 were Limnea peregra and L. truncatula. Clausilia laminata, and 

 C. v^igosa were found by other members. One striking feature 

 was the scarcity of Helix nemovalis. I only found this at one 

 place. Quite near to Middleton, below the Railway Station close 

 to the river. Helix arbustorum was very plentiful, and at the same 

 place I got Helix arbustorum var. flavescens and Helix hortensis. 

 On Tuesday, in crossing the country to the River Tees 

 below Widdy Bank Farm, I got Helix arbustorum, H. 

 gramdata and Zonites cellarius. At the top of Cauldron Snout, 

 in the stream, 1 got quite a number of Ancylus fluviatilis and 

 Limnea peregra.
