Hugel's Helix. Shell imperforated, lenticular, rather 

 solid, more or less keeled, sliining, finely striated, 

 decussated beueath the lens with very minute spiral 

 lines, yellowish, variously encircled with green or 

 brown ; spire but little raised ; whorls four to five

This is an extremely variable species, both with respect 

 to form and colouring. The sharply keeled state repre- 

 sented at Fig. d and e is U. Hanleyana, and the grey 

 variety at Fig. /is II. anuena.

The button Helix. Shell imperforated, lenticular, solid, 

 sharply keeled, obliquely finely striated, yellowish- 



wliitc, with a single rather broad grey-black baud on 

 each side remote from the keel, and ornamented with 

 a chestnut sutural line; spire but little raised; 

 whorls four to five, rather convex, the last shortly 

 deflected in front ; aperture nearly horizontal, angu-

There is little or no variation in this species. Of the 

 many specimens collected in the above-named locality by 

 Mr. Cuming, all are of the same uniform size and colouring.

Gmelin's Helix. Shell imperforated, globoscly de- 

 pressed, rather solid, irregularly rugosely indented, 

 keeled, shining, pale green, encircled with white at

 shortly expandeil, arched luileriorly, basal edge re- 

 flected, columellar edge slanting, dilated, callous-

.\ delicate and very characteristic species, of which the 

 surface is irregidarly iudente<l tlirougliout. It is of a 

 peculiar light sea-green colour, encircled by a narrow
