282 Brode : Yorkshire Naturalists at Cox-wold and Kilbiirn.

The conchologists, though few in number, worked assiduously, 

 and several additions were made to the previous records for the 

 district. Perhaps the most interesting capture was Helix lapi- 

 cida, taken near Roulston Scar, as this snail, even where it is 

 known to exist, is difficult to find 'at home.' Mr. J. E. Crowther, 

 President of the Section, gives the following list of 29 species : — 



Arion ater. Helix hortensis. 



Arion hortensis. Hygromia hispida. 



Arion circumscriptus. Helicella caperata. 



Ag-riolimax agrestis. Buliminus obscurus. 



Vitrina pellucida. Pupa cylindracea. 



Vitrea cellaria. Clausilia bidentata. 



Vitrea alliaria. Clausilia laminata. 



Vitrea nitidula. Cochlicopa lubrica. 



Vitrea crystallina. Carychium minimum. 



Vitrea fulva. Planorbis albus. 



Pyramidula rotundata. Planorbis spirorbis. 



Helicigona lapicida. Limnaea peregra. 



Helicigona arbustorum. Sphaerium corneum. 



Helix aspersa. Pisidium fontinale. 



Helix nemoralis. 



Among the members of the section for Vertebrate Zoology 

 were some who had the advantage of the longer time which 

 a week-end stay at Coxwold gave them. Mr. Kenneth McLean 

 reports that the absent members certainly missed a splendid 

 opportunity for the study of bird and animal life. The district 

 is so diversified and the changes so abrupt that many kinds 

 of birds were found 4 near neighbours ' which are generally 

 separated by great distances. For instance, the sheltered 

 wooded valleys are inhabited by Willow Wren, Wood Wren, 

 Whitethroat, Tits, and Finches in large numbers, while but 

 a few hundred yards above, on the wide-stretching moors, is the 

 habitat of the Red Grouse, Curlew, Ring Ousel, Wheatear, etc. 



Byland Abbey was seen to shelter a much larger number of 

 inhabitants than ever it had in its bygone days of magnificence, 

 for every hole, crevice, and cranny is now the home of Jackdaw, 

 Starling, or Sparrow, and the grand old ruins were alive with 

 the call of hungry youngsters. 



Although many of the tree trunks in the neighbourhood bore 

 the marks of the Woodpecker's strong bill, not a single specimen 

 was seen or heard. Amongst the Spruce and Larch on the 

 richly-wooded hill-side was seen the beautiful little Goldcrest, 

 active in search of food, while the twitter of the Wood Wren
