296 Roebuck : Molluscan Fauna of Langstrothdale. 



Bale A perversa (L.)- 



Abundant on walls on east side of Cray Gill, T. P. On walls in 

 Oug-htershaw villag;e, 1,250 feet altitude, J. W. T. 

 Clausilia bidentata (Strom). 



Buckden Gill, Oughtershaw, Buckden Wood, not very common. 

 Clausilia cravenexsis Taylor. 



Raysg-ill, August 1890, T. B. Woodd. 



On walls throughout the district from Starbotton to Oughtershaw, 

 abundant. 



In this connection it is of interest to note that a wall in Starbotton 

 village is the classic locality for this species, as it was here that I 

 collected the type specimens from which Mr. Taylor described the 

 species as new to science. The form, of course, was one well-known 

 to collectors under the name of CI. diibia, but as it was not the form 

 described on the Continent under that name, and was specifically 

 distinct from our other British Claiisilice, it was necessary to describe 

 it as new. It is a species which is, I believe, peculiar to the North of 

 Eng-land.
