VALVATA CRIST AT A IN THE VALE OF YORK. 

 By W. nelson. 



This spring, whilst cohecting in the neighborhood of South 

 Milford, I found a single specimen of this shell. On Whit Monday, 

 collecting near Selby, I found a number of this species amongst 

 decaying vegetation. In the same locality Bytliiiiia Lcachii 

 was very abundant, along with a number of other commoner 

 species. 



CLAUSILIA RUGOSA var. ALBIDA AT SMEATON, 

 YORKSHIRE. 



By W, nelson. 



In the spring of 1878, during the excursion of the Yorkshire 

 Naturalists' Union, whilst searching among a heap of loose stones 

 for Clausilia laminata, which was plentiful in this locality, I found 

 two specimens of Clausilia rugosa var. albida. The type of this 

 species was somewhat rare; the only other species associated with 

 it being Zonites fulvus and Vertigo pygmcBa.
