The slightly worm-eaten Helix. Shell with a co- 

 vered umbilicus, subsemislobose, keeled, globosely 

 convex at the upper part, worm-eaten, rather flat, 

 beneath dirty-white, with a thread-like keel, and 

 with a suture tubercularly eroded ; whorls five, rather 

 flat ; aperture lunar, lip simple, slig;htly edged, an- 

 gled, upper margin a little deflected, basal rather 

 thickened, columcUar dilated, reflected, covering the 

 umbilicus.

Hab. Algeria. 



Closely allied to II. Ludovici, but with a contracted 

 covered umbilicus.

The matted Helix. Shell umbilicated, depressed, 

 sharply keeled, plaited, rather flat at the upper part, 

 variegated with white and horn, marked with rosy- 

 brown stripes, interruptedly banded beneath the keel; 

 whorls four to five, flat, the last deflected in front ; 

 aperture angularly lunar, lip simple, margins nearly 

 approximated, columellar reflected.

Jcillet's Helix. Shell imperforated, subglobosely de- 

 pressed, whitish, encircled with five bands of light 

 brown; spire convex; whorls five to six, increasing 

 slowly, the uppermost flat, the last very much de- 

 fleeted in front ; aperture ovately lunar, transverse, 

 very oblique, columella and interior of the aperture 

 chestnut, lip a little expanded, columellar margin 

 drawn out, callous, gibbous.

 Helix TTagneri, llossmiisler. 



Hab. Algeria; Wagner. 



It is doubtful whether this is anything more than a va- 

 riety of H. lactea.

The worm-eaten Helix. Shell umbilicated, orbicular, 

 keeled, convex on both sides, white, crisply finely 

 wrinkled, rude ; spire dcpressly hemisphcrioal ; whorls 

 five, convex in the middle, last whorl a little deflected 

 in front, abruptly angled round the umbilicus ; aper-

 by a callosity, columellar margin thick and reflected. 



Olivier, Voyage, vol. ii. pi. 221. pi. 31. f. 4.

An opake ehitlk-white shell, chiefly distinguished by the 

 compressly angled growth of the whorl around the wall of 

 the umbilicus.
