minute species in Ireland. In December, 1883, I 
found a single live specimen near Coleraine. As I 
was doubtful of its being actually alpestris, I sent it

of the northern counties of England. 
6. V. supstRiaTA (slightly striated). 
Ovate, thin, semi-transparent, glossy, very strongly and 
obliquely striate in the line of growth; whorls four and a 
half, cylindrical; spire very abrupt; swtwre remarkably 
deep; mouth semi-oval, outer margin constricted; teeth 
five to six (two or three on the body, one or two on the 
columella, two inside the outer lip) ; wmbilicus small.

7. V. PUSILLA (minute).

a half; spire more tapering than that of most members 
of the genus; very slightly striate in the line of growth; 
mouth semi-oval, constricted in the outer margin, which is 
rather thick; whorls four and a half to five; teeth six to
