YORKSHIRE NATURALISTS IN LOWER WENSLEYDALE . I 73 



were noted down. Balea perversa was twice taken, and Buliniiis 

 obsciirus was not uncommon. The other species observed were — 

 Zua ludrica, Vitrina pellucida, Helix hispida, II. toiundata^ H. Jior- 

 te?isis, If. pulchella, H. ericetoriwi^ and Clausilia riigosa. Near the 

 Nick, Mr. Braim, of Pickering, was lucky enough to secure an 

 immature specimen of the rare Umax cinereo-fiiger, which was 

 undoubtedly the event of the day. Keeping along the scars above 

 Preston, Zonites 7-adiaiiiliis was met with under stones on the ledges, 

 a somewhat unexpected locality. H. rupest7'is was still abundant, 

 and H. ericetorum not uncommon. B2ili7mis obscurus was frequent 

 under stones, associated with H. I'upestris and H. pulchella. The 

 list for Preston Scar, in addition to those already mentioned, included 

 H. rofmidafa, H. 7iemoraIis (dead), H. horfeTisis, Pupa U77ibilicata^ 

 Clausilia rugosa,Ario7i hortensis^ and in a small drinking-trough on the 

 moor, Ii77incea tr2i7icatula (fine) was secured. On reaching Leyburn 

 Shawl, Clausilia lami7iaia, ZoTiites 7iitidulus^ Vi/ri7ia, Azeca, Helix 

 horte7isis, and Ario7i bou7'guig7iati were boxed, and on meeting with 

 a contingent who had worked along the valley through Bolton Woods, 

 Helix aspersa, SucciTiea elega7is^ ZoTiites cellarius^ Z. alliariiis, and Zua 

 were reported, whilst Mr. Wm. Cash, F.G.S., F.L.S., stated he had 

 observed ^//^y'/z/j fluviatilis,Ii77i7icEa pe7-egra, 2iY\<\ A7wdo7ita {a7iati7ia?) 

 in the River Ure near Leyburn ; and later on, the ornithologists 

 brought Z. 7iitiduliis, found near Locker Tarn. The Section had there- 

 fore to report, a total of thirty-five species as having been observed 

 during the day, of which four were fluviatile and thirty-one terrestrial. 



For the Geological Section, Mr. S. A. Adamson, F.G.S., of Leeds, 

 secretary, the only sectional officer present, reported that from 

 Leyburn Station, Mr. WiUiam Home, F.G.S., pointed out the 

 character of the section through which the railway passed. It was 

 composed of a tough boulder clay, the included stones being local 

 in their origin, the whole being produced by a glacier, which 

 descended from the head of the dale, grinding and polishing the 

 rocks as it passed along. From Redmire Station, where the members 

 alighted, Mr. Home conducted the party to Bolton Castle, the 

 famous feudal stronghold of the Scropes, and although geologists 

 in the field have little time to spare for archaeology, yet here was 

 something specially interesting. Mr. Home had, in March 1884, 

 discovered the remains of a human skeleton on the hill-side west of 

 Leyburn, and near it found a bone implement made of a deer's horn. 

 In xMarch 1885, he found another skeleton in the same locality, and 

 then succeeded in discovering the entrance to a cave, where a 

 number of human and other bones were i)icked uj). This cave he 

 has named the ' Lady Algitha Cave,' and the pre-historic relics found 



June 1888. M
