Stuart's Helix. Shell obsoletely umbilicated, depressly 

 turbinated, striated, white, variously ornamented 

 with brown and blackish bands ; spire broatUy co- 

 noid ; whorls six, but little convex, last whorl rather 

 flattened at the base ; aperture very obli(jue, lunar ; 

 lip simple, upper marLjin arched forward, columellar 

 margin shortly reflected, almost covering the um- 

 bilicus.

Hab. Island of Celebes. 



Helix Stuartus somewhat resembles Helix Pan of the 

 Philippine Islands in general aspect. In that species the 

 marking is produced by the varied pattern of the epider- 

 mis ; in this it is produced by colour stained in the shell. 



Species 463. (Mus. Cuming.) 



Helix Bataviana. Hel. testd umbilicatd, depreao- 

 globosd, tenui, obtuse carinatd, superne ciiinamomed, 

 oblique confertim costiilatd, subtus castaiied, striata, 

 vermm umbilicum pallida, area urniilicali castaned; 

 anfractibus sex ad septem, vix convexiusculis ; aperturd 

 angulalo-lunari ; peristoniate simplici, ad umbilicum 

 arcuatum reflexo. 



The Batavia Helix. Shell umbilicated, depressly glo- 

 bose, thin, obtusely keeled, cinnamon at the upper 

 part, obliquely closely ribbed, chestnut beneath, stri- 

 ated, pale towards the umbilicus, umbilical area 

 chestnut ; whorls six to seven, but little convex ; 

 aperture angularly lunar ; lip simple, reflected in an 

 arched maimer at the umbilicus.

The colouring of this species, as above described, is ex- 

 tremely ebaructeristic. 



Species 461. (Mus. Cuming.) 



Helix cidaris. Hel. testa subumhilicata, orbiculato-co- 

 noided, oblique costulato-ntriatd, lubobtcuri corrugatd 

 et malleatd, flavescente-aWd, fascia fusco-rubrd infra 

 peripheriam cingulatd ; spird lurgidd, apice obtiua : 

 anfractibus sex, viz convexiusculis ; aperturd rolnn- 

 dalo-lunari ; peristomate simplici, acuta, inarginr coIh- 

 mellari breviter dilatato, refexo. 



The tubba.v Helix. Shell slightly umbQicated, orhi- 

 cularly conoid, obliquely rib-like striated, somewhat 

 obscurely wrinkled and indented, yelloHJsh-whitc, 

 encircled below the |)eriphery with a red-brown band; 

 spire swollen, obtuse at the apex ; whorls six, slightly 

 convex ; aperture rotundatcly lunar ; lip simple. shaq>, 

 columellar margin shortly dilated and reflected.

Hab. Island of Timor. 



The rib-like stria; are verj' regular and well-formetl on 

 ilie first five whorls; in the last whorl they begin to fade, 

 and as they become more indistinct, so is the surface more 

 indented and wrinkled. 



Species 405. (Mus. Cuming.) 



Helix DISTINCTA. Hel. testd umbilicatd, tubgtobotd, lur- 

 gidd, subtiliter corrugatd et malleatd, n^e»cr»te-tpa-

The distinct Helix. Shell umbilicated, somewhat 

 globose, swollen, finely wrinkled and imlent«l, ml- 

 dish-fawn, with a whitish band at the p«-riphrn. 

 darker below the periphery, then white ; spire short . 

 whorls five to six, convex, last whorl s^jmiwhat

Distinguished from 11. moHOCOitalis, to which it is allied, 

 by its more swollon spiral form, fine indently wrinkled 

 sciUpture, and light reddish-fawn coloiirinn
