HELIX.— Plate LXXXl. 



while kcol, edged and reticulated with elHstiiut lines, 

 suddenly detlecled at the upper j)art and at the keel, 

 slightly gibbous at the base near the columella ; 

 aperture narrow, very oblique, somewhat triangular ; 

 lip simple, chestnut-edged, right margin straight, 

 basal margin shortly reflected, columellar margin very 

 slanting, dilated inwardly, excavated, dark chestnut.

Halt. St. Christoval Island, Salomon's Group. 



A rather solid pale straw-coloured hyaline shell, en- 

 circled with delicate opakc-white hair Unes, with an opake- 

 white keel at the periphery, marked with chestnut lines 

 and dots. The lip ;iik1 columella are conspicuously stained 

 with chestnut.

Kurr's Helix. Shell umbilicatcd, depressed, thin, 

 slightly roughened beneath the lens with distant 

 punctures, diaphanous, horny -white, ornamented 

 with a narrow red band ; spire flat ; whorls four to 

 live, the first rather convex, the last gradually de- 

 scending, slightly flattened on both sides, rather 

 drawn out in front ; aperture oblique, somewhat tri- 

 angularly lunar ; lip simple, thin, margins approxi- 

 mating, upper margin broadly expanded, basal mar- 

 gin reflected, columellar margin short, triangulariy 

 dilated.

Hah. ? 



In some examples of this species, there is a second faint 

 band a little below the first.

The finely sprinkled Helix. Shell umbilicatcd, tur- 

 binated, linely striated, opake, rather thin, pale stniw 

 or cinnamon-coloured, very closely sprinkled with 

 white dots ; spire conoid, rather obtuse and blackish 

 at the apex ; suture middling, edged with chestnut ; 

 whorls six, rather convex, the last slightly angled, 

 rather flat at the base ; columella oblique, slightly 

 arched, rather hollow, white, chestnut-edged; aperture 

 large, lunar-oval ; lip simple, shortly expanded. 



Pfeiffer, Pro. Zool. Soc. 1845, p. 124. 



Hab. ? 



The delicate white dots which characterize this shell 

 are quite suj)crfieial, composed of hydrophanous e])idermis. 

 Unlikely as it may appear, this species runs very closely 

 into varieties of H. fusco-cincta, from Jamaica. 



Species 434. (Mus. Cuming.) 



Helix Greenwoodii. Hel. testa subampUler umbill- 

 . catd, orbiculari-dcpressd, aperturam versus oblique 

 productd, oblique coiifertissime corrugato-slriatd, oU- 

 vaced ; spird obtuse depressd ; au/ractibus qualuor,

Greenwood's Helix. Shell rather largely umbilicatcd, 

 orbicularly depressed, obliquely produced towards 

 the aperture, obliquely very closely striated in a 

 wrinkled manner, olive ; spire obtusely depressed ; 

 whorls four, flatly convex, the last peculiarly diago- 

 nally plicated in the middle, angled around the um- 

 bilicus ; aperture lunar-oval ; lip simple, margins ap- 

 proximating. 



Gray, Pro. Zool. Soc. 1849, p. 165. 



Hab. New Zealand. 



An interesting species, of the same peculiar typical cha- 

 racter as H. Duuuitr, Sp. 425, from which it diflers mainly 

 in having a larger umbilicus, though the shell is smaller, 

 and in having several folds ranging diagonally about the 

 periphery of the last whorl.
