HELIX GENTIL. 
TAB. CXLY. 
Spec. Cuar. Discoid, gibbose, smooth, with a 
spiral band along the upper part of the whorl ; 
aperture large, expanded, elliptical. 
R aruer less than an inch high, and an inch anda half 
wide; the strie of growth are rather obscure, except 
near the upper part of the whorl, where they run into a 
narrow sulcus that forms the spiral band. 
I am favoured with permission to draw this pretty 
cast by Mrs. Gent, whose name I have given it in com- 
memoration of that scientific zeal which trusted an 
unique tender micaceous sandy cast to travel so far. I 
presume it to be an Helix, as somewhat according with - 
tab. 10 and the position of the band is probably a good 
characteristic distinction: it was gathered in the mica- 
geous sand formation near Devizes.
