LovE\'s Heli.x. Sbell umbilicated, rather flattened at 

 the ujipcr part, inflated at the base, thin, horny, 

 obliquely scarcely ribbed ; spire rather flattened, 

 rather sharp at the apex ; whorls five, rather flattened 

 above, last whorl obtusely keeled above the periphery, 

 with the ribs hairy ; aperture somewhat angularly 

 lunar ; lip simple, sharp, eolumellar margin dilately 

 reflected, partially covering the umbilicus.

Uab. Natal, South .Vfriea. 



This transparent homy species, which is characterized 

 by a peculiar depression of the upper surface, is scarcely 

 ribbed in sculpture, but obtains that appearance from 

 being overlaid with very delicate oblique strips of hairy 

 epidermis. 



Species 196. (Fig. a, b, Mus. Cuming.) 



Helix doliolum. Hel. testd umbilicatd, turbinatd, con- 

 fertissime et minute costulato-striatd, pellucidd, non

 aperturd depressd, late lunari ; peristomate simjdicis- 

 aimo, recto. 



The little barrel Helix. Shell umbilicated, turbi- 

 nated, very closely minutely rib-like striated, pellu- 

 cid, not shining, homy ; spire turbinated, rather ob- 

 tuse at the apex ; whorls five, rounded, the last 

 rather flattened at the base ; apcrtui'e depressed, 

 broadly lunar ; Up very simple, straight. 



Pfeiffek, Pro. Zool. Soc. 18-16, p. H. 



Hab. Sibonga, Island of Zebu, Philippines ; Cuming. 

 A minute turbinated horny species, with rounded whorls, 



more proportionably enlarged in the accompanying plate 



than the rest of the flgures. 



Species 197. (Mu.s. Cuming.) 



Helix MUCRONATA. Ud. tntd imper/oratd, conoided, 

 tenuiisimd, corned, acuta carinatd, roiiceiilrici cotlrl-

The pointed Helix. Shell imperforated, conoid, very 

 thin, homy, sharply keeled, concentrically rib-iike 

 striated, and decussated beneath the lens with i lose- 

 set, minute, spiral engraved stria?, shaq) at the apex, 

 olive-gi-ecn, pellucid ; whorls four, flatly convex, last 

 whorl obliquely inflated, very sharply angnlatod at 

 the periphery ; aperture large, nearly horizontal ; lip 

 simple.

I doubt very much if this shell belong to a Helix. It 

 is of a peculiar thin homy substance, without any indica- 

 tion of an internal calcareous lining. 



Species 198. (lug. a, b, Jlus. Cuming.) 



Helix VERKICOSA. Hel. testd umbilicatd, lubdeprrstd.

The varnished Helix. Shell umbilicated, rather de- 

 pressed, vcr)' thin, pellucid, yellowisli-honiy, oblifpicly 

 rib-like striated at the upper part ; spire rather flat- 

 tened ; whorls four, rather convex, last whorl convex 

 at the base, rather smooth, as though varnish.d ;
