Hazelslack Hall, for which place it is recorded by Mr. J. W. Jackson 

 in the Jourtial of Conchology of January last. Thence we pass to 

 Arnside, at which place the Rev. C. E. Y. Kendall found a colony in 

 April, 1908. We now pass out of Westmorland into West Lanca- 

 shire (V.C. 60) and have it recorded for Silverdale, where it was 

 found by Messrs. Dean and Jackson in November, 1904, and re- 

 corded in December the same year. 



Working south-east, we come to Borwick, the most southerly point 

 of its distribution in this district so far recorded, where Mr. Dean 

 found a flourishing colony in May, 1908. Again, some miles to 

 the north-east, the Rev. C. E. Y. Kendall found it at Whittington, 

 still in Lancashire, m May, 1908 ; and re-crossing the border we 

 come to Kirkby Lonsdale in Westmorland, where it occurs near the 

 Devil's Bridge, and was found by Mr. Dean in August, 1905, and 

 recorded in September of the sam.e year. 



This completes our chain of localities, though doubtless further 

 search might make it even longer. 



The distribution of this shell in North Westmorland is still very 

 undefined. It was recorded for Kendal, Ambleside, and Grasmere 

 many years ago, and has more recently been shown to be at Winder- 

 mere, for which place it was recorded by Mr. R. Roberts in 1906. 

 It is very abundant again in the neighbourhood of Penrith, and 

 again at Clifton, at which places it was found by Mr. Dean in 

 September, 1907 ; both these localities are in Westmorland, but 

 some miles apart, and on opposite sides of the river Lowther. 



All these habitats are more or less similar. An old, moss-covered 

 wall, usually limestone, sometimes slate, always on a limestone 

 soil, covered in parts with the common small-leaved ivy, more or less 

 under trees, but not under a hedge — such is the usual home of 

 V. alpestris. One side of the wall seems always to be well sheltered, 

 and a wall in a bleak and exposed position hardly ever yields any 

 results. The altitude is generally a low one, and several of the best 

 localities are close to a stream or river. The Clifton locality is note- 

 worthy in this respect ; the three species — V. alpestris, V. pusilla, 

 and V. sitbstriata — occurring in great abundance along the embank- 

 ment wall of the river, almost at the water's edge. 



We have also noticed that Vertigo alpestris very commonly, but not 

 always, occurs along with V. pusilla, specimens of both species being 

 often found on the same stone. We give below lists of localities 

 showing where both occur together and where they occur separately, 

 and we may remark that we have here eight new locality records for 

 Vertigo pusilla and no fewer than ten new records for V. alpestris. 



The new records for V. alpestris are : —
