The flattened spire Helix. Shell umbilicated, sub- 

 orbiculnrly depressed, obliquely groove-plaited, olive- 

 yellowish, white-flamed and interruptedly five-banded; 

 whorls five, the uppermost flattened, keeled, the last 

 rounded, suddenly deflected in front ; aperture very 

 oblique, transversely oval ; lip white-edged, margins 

 nearly eontiguous, joined by a raised callosity, upper 

 margin expanded, basal reflected, eolumellar margin 

 dilated, half-covering the umbilicus. 



Oliviek, Voy. Levant, vol. i. p. 415, pi. 17. f. 7. 



Hab. Islands of Crete and Rhodes. 

 This appears to be a variety of the preceding species, in 



which the whorls are more widely convoluted, and tiie 



umbilicus only partially covered by the eolumellar margin.

The cream-colodred Helix. Shell imperforated, glo- 

 bosely depressed, transversely dilated, whitish or 

 yellowish, generally red-banded and white-punctured ; 

 whorls four to five, the uppermost flattened, the last 

 convex, deflected in front ; aperture vei"y oblique,

Hab. Southern Europe and Nortii Africa. 



Kxtremely variable in painting and in size, but always 

 characterized by the chestnut-black enamel of the aperture.

The solitcde-lovino Hklix. Shell rather deeply um- 

 bilicated, orbicularly (k'j)resscd, rather discoid, chalk- 

 white ; spire rather flattened, suture distinct ; whorls 

 five, somewhat rounded, irregularly indented and 

 wrinkled ; a])erture rather small, obliquely horizontal, 

 nearly circular; lip thin, margins approximating, in- 

 terior stained with brown. 



Boissier, (Mus. Cuming). 



Hal). Palestine. 



In the chalk-white substance, in the peculiar crinkling 

 of the surface, and in the coloured interior, this shell re- 

 sembles H. Ehrenbergi, but it is widely diflcrent in form.

 The long-mouth Helix. Shell openly umbilicated, 



orbicularly depressed, opakc, very finely granulated 



at the upper part, yellowish, with a single red zone ; 



whorls five, rather convex, the last descending in 



front ; aperture broadly lunar ; lip broadly reflected, 



white-edged, palate rather thickcued.
