I may also mention that I met with Balea perversa (L.). 

 and Carychium minimum Mull, high up under the clerestory 

 windows of Beauvais Cathedral. Perhaps they originally came 

 on the twigs brought there by the pigeons for building their

Helix nemoralis monst. sinistrorsum. — I took a speci- 

 men of this variety while collecting shells last September on the 

 railway bank at West Drayton, Middlesex. It is a dead shell, 

 but in fairly good condition. — F. G. Fenn, Syon Lodge, Isle- 

 worth, October, 1888. 



Vertigo minutissima (Hartm) in Gloucestershire. — 



Mr. C. H. Falloon has recently sent me eight specimens of this 

 species from Clifton, Bristol. I believe this species is new to 

 Gloucestershire, as the only record I know of it from the South 

 of England is the Isle of Wight. — J. W. Williams, D.Sc. 



Note on Vertigo tumida West. — In 1867 Prof Wester- 

 lund in the "Mai. Blatt.," p. 203, described as new a Vertigo 

 which he stated had been confused with V. pusilla up to that time. 

 He described it as closely allied to V. pusilla, but distinguished 

 from it by its smaller size, more ventricose shape, and thus having 

 a comparatively broader mouth. The darker color of the shell 

 and nearly imperceptible umbilical fissure were also points of 

 difference. Dr. Jeffreys, in "Annals and Mag. Nat. Hist.," p. 

 381, 1878, accepted Dr. Westerlund's view of the distinctness of 

 the new species, but expressed a doubt whether it was more than 

 a dwarf form of V. pusilla, as which he had regarded it until that 

 time. From a type specimen which Dr. Westerlund has kindly 

 sent me it would seem that a more extended examination has 

 led him to regard V. tumida as merely a variety of V. pusilla. 

 My specimen is labelled in Dr. Westerlund's own hand Vertigo 

 pusilla Mull. var. tumida West. — J. W. Taylor, June ist, 1888.
