OCCURRENCE OF A NEW BRITISH VARIETY. 

 Pupa secale var. Boileausiana, Charp. 



By JOHN W. TAYLOR. 



Amongst some typical specimens of Pupa secale collected by 

 Mr. W. Nelson at Dorridge, near Knowle, Warwickshire, is an 

 example of this interesting variety, which has not previously been 

 found in this country. It is distinguished from the type by its 

 "smaller size, the larger plication on penultimate whorl being 

 always double, and by the presence of a prominent additional 

 fold at the angle of the columella." 



It is the first British specimen I have seen of this interesting 

 Pyrenean form.

DESCRIPTION OF a NEW VARIETY of PUPA SECALE. 

 Pupa secale var. edentula. 



By JOHN W. TAYLOR. 



Shell smaller, thinner, smooth and glossy; striation regular and 

 fine on the upper whorls, gradually becoming fainter and 

 more irregular on the lower ones; apertural plications 

 obsolete. 

 This variety was found by me in September, 1877, at the 

 foot of the rocks near Ingleton in Yorkshire. The specimens of 

 the type found in company with it partake of many of the 

 peculiarities enumerated. It furnishes an approach to the conti- 

 nental species, Pupa avena.
