The edoe-lmbilicated Helix. Shell very broadly openly 

 umbilicatcd, flatly orbicular, very depressed, subdis- 

 coid, convex beneath, dirty straw-colour, scmitrans- 

 parcnt, beneath the lens very finely decussately stri- 

 ated ; spire thinly margined ; whorls six to seven, 

 increasing slowly, verj' sharply keeled ; aperture com- 

 prcssly hatchet-shaped, lip simple ; umbilicus pecu- 

 liarly edged. 



Pfeiffer, Pro. Zool. Soc. 183-i. 



Hob. Japan Archipelago. 



A remarkable species from Japan, peculiarly typically 

 distinct about the umbilicus, which has the appearance of 

 being artificially scooped out. 



Species 1359. (Mus. Cuming.)

 tiis contexd, sordide albd, sub lente viiniitissimi deciis-

 The little pagoda Helix. Shell imperforated, conoid, 

 convex below, beneath the leus very minutely de- 

 cussately striated ; spu'c somewhat obtuse ; whorls 

 six, convexly flattened, keeled at the pcripherj', keel 

 conspicuously turned up ; aperture ovately hatchet- 

 shaped, lip scarcely reflected. 

 Pfeiffeu, Pro. Zool. Soc. IRot. 



Hab. ? 



A conical pagoda-likc dead-white shell, chiefly charac- 

 terized by the keel which encircles the periphery of the 

 whorls being turned up all round.

TuE ciRVED-TOOTH Helix. Shell imperforated, sub- 

 globose, rather tliick, semitransparcnt-white, ob- 

 liquely striated, grouosely indented beneath ; spire 

 obtuse ; whorls four, convex, the last somewhat ob- 

 scurely keeled, keel opakc-white ; aperture lunar- 

 ovate, lip a little reflected, at the columella as far as 

 the base broadly appressly callous, with a cun-cd 

 tooth ; columella excavated. 



Pfeiffer, Pro. Zool. Soc. 1854. 



Hab. ? 



A very characteristic species, semitransparent -white 

 though solid, encircled with a somewhat obscure keel, 

 which, near the aperture, is opakc-white. From the colu- 

 mella to the base the lip has a broad callous shelf on it, 

 ending in a curved tooth.

Species 1361. (Mus. Cuming.) 



Helix sCBVITREA. Uel. testd tubanguste profundi urn-

 tenuissime decutsatim striata; spird elecald, apice 

 snbobtusd ; anfractibns sex ad septein, plaiiulaf is, cari-

The class-like Helix. Shell rather narrowly deeply 

 umbilicatcd, conoid, flatly convex at the base, sub- 

 glassy-white, very finely decussately striated ; spire 

 raised, rather obtuse at the apex; whorls six to 

 seven, flattened, kcilrd, then convex; aperture ob- 

 liquely lunar, callously reflected at the bas*', broadly 

 appressed at the columella, half-covering the um- 

 bilicus.

Ilab. Moluccas. 



A rather solid obtusely conical species, of transparent- 

 white substance, keeled at the periphery.
