Mr. G. H. Taylor supplies the following information about this 

 species : — "I found it in plenty at Lower Allithwaite (August, 1907) 

 in a dry ditch, near to the railway crossing leading to Humfrey 

 Head. The shells (dead) were accompanied by P/anorh's spirorbis 

 and Pisiifia."

 a ledge at Meathop Fell, carried there by flood early last year 

 (1907) (J.W.J.).

var. albina Taylor. — Cark, 1903 (C.H.M.). 



Pomatias elegans (Miiller). — This shell seems comparatively 

 rare and local in its range, and was taken in one locality only, 

 viz. : in the hedgerow skirting the foot of Meathop Fell on the road 

 to Lindale, beyond the gasworks to the north-east. The writer at 

 first thought it quite likely that this locality would be its most 

 westerly limit in the Grange district, the river Winster and the ex- 

 tensive marshland preventing its spread further to the west. This 

 was only an opinion based on the fact that absolutely no evidence 

 of it was apparent beyond this limit, although the species is very 

 common across the river Kent, on Arnside Knott to the south, 

 but it has since been found at Humfrey Head, four miles away 

 to the south-west, and consequently it may yet be found between 

 these two extremes. The discovery of the species at these two 

 distant points seems fairly conclusive evidence that at some early 

 geological period, the land was continuous here, and that the river 

 Kent with the aid of the sea and other denuding agencies has 

 long ago carried away this land, Arnside Knott, Humfrey Head, 

 and the cliffs at l^indeth being the remnants of this destruction.
