The noble Helix. Shell narrowly umbilicated, orbi- 

 cular, minutely indentcdly decussated tliroughout 

 with striae, burnt-fulvous, whitish beneath ; whorls 

 six to seven, convex, the last rounded, encircled at 

 the periphery with a very dark chestnut baud ; aper- 

 ture obli([ucly lunar ; lip simple. 



Pi'EiFFER, Pro. Zool. Soc. 1849. p. 127. 



Hab. Borneo and the Philippine Islands. 



Distinguished from the two species figured beneath it 

 in the accompanying plate, by the more rounded fonn of 

 the whorls and of the shell. 



Species 382. (Mus. Cuming.) 



Helix Luhuana. Uel. testa late umbilicatd, suborbicu- 

 lari, depressiusculd, lineis incrementi irregulariter ru- 

 gulosd, brunneo-olivaced ; anfractibus sex, convexis, ul-

 conniventibus, supero arcuato, expanso, basali breviter

The Loo-Cuoo Helix. Shell broadly umbilicated, nearly i 

 orbicular, rather depressed, irregularly wrinkled with 

 lines of growth, lirown-olive ; whorls six, convex, 

 the last rounded, encircled above the middle with a 

 narrow blackish band, slightly descending in front, 

 rather compressed and funnel-shaped around the 

 umbilicus ; aperture broad, rotundately lunar ; lip 

 slightly thickened within, margins approximating, 

 upper margin arelied, expanded, basal margin shortly 

 reflected, eolumcUar margin but little dilated. 



Sowerby, Zool. Beeehcy's Voyage, p. 110. pi. 35. f. 4. 



Hab. Loo-Choo Islands. 



Characterized by a rather depressed spire and by an 

 open perspective uhibiiicus. 



Species 383. (Mus. Cuming.) 



Helix meecatoria. Ilel. testa umiilicala, turbinato- 

 depressd, costulato-striatd, oUvaceo-brunneu, zona unicd 

 nigricante, utrinque pallide marginatd, circiimJald ;

 cottvexiusculis, ultimo obsolete angulato, bani injlalu ,- 

 mnbilico angustissimo, vix pernio ; aperturd tiinart ,- 

 peristomate incrassato, breviter refiexo. 



The merchant Helix. Shell umbilicated, turbinatcly 

 depressed, rib-like striated, olive-brown, encircled 

 with a single blackish band pale-edged on either 

 side; spire raised, rather obtuse; whorls six to seven, 

 rather convex, the last obsoletely angled, inflated at 

 the base ; umbilicus very narrow, but little open ; 

 apertm-e lunar ; lip thickened, shortly reflected. 



Gray, Pfeiiler, Zcitscliril't fiirMalac. 1845, p. 154. 



Hab. China. 



Closely allied to the preceding, but less depressed and 

 with a narrower umbilicus. The striae of growth obtain 

 almost the character of fine ribs. 



Species 384. (Mus. Cuming.) 



Helix obliquata. Hel. testa anguste umbilieata, sub- 

 orbiculari, depressd, slriis undique minute matleato- 

 decussatd,fulvescente, subtus atbidd ; anfraclibuD i/uiu- 

 gue ad sex, convexis, ultinw rotundato, prominenU, 

 fascia castaned, superni pallide marginatd, cingulato ; 

 aperturd oblique lunari ; peristomate simplici. 



The obliquely-turned Helix. Shell narrowly um- 

 bilicated, nearly orbicular, depressed, minutely in- 

 dentcdly decussated throughout with striie, fulvous, 

 whitish beneath ; whorls five to sL\, convex, the lust 

 rounded, prominent, encircled by a clicstnut band 

 pale-edged along the upper side ; aperture obliquely 

 lunar ; lip simple. 



Hab. Borneo. 



This species is certainly distinguished from those figured 

 above and below it in the accompanying plate, by a smaller 

 and more depressed spire and by tlie more swollen and 

 prominent growth of the last whorl, wliich imparts an 

 obliquely lunar form to the aperture.
