The grained Helix. Shell imperforated, orbicular, 

 depressly conical, solid, pale brown, sprinkled with 

 small white grains ; spire convex, obtuse ; whorls five, 

 rather convex, the last sharply keeled, deflected in 

 front, rather gibbous, flat at the base, scarcely fur- 

 rowed; aperture nearly horizontal, transversely tri- 

 angularly oval; lip white, thickened, margins joined 

 by a callous layer, upper margin expanded, a little 

 reflected, basal margin broadly reflected, furnished 

 with two teeth not entering.

Hai. Trinidad, Granada ; Beck. 



Very closely resembling B. liina, from which it differs in 

 being more conspicuously grained, and in havinj two 

 teeth within the aperture.

The discoloured Helix. Shell imperforated, depressly 

 globose, striated, obsolelely grauulated, red-chestnut ; 

 spire semiglobose; whorls four, the uppennost rather 

 flattened, the last inflated, angled, ornamented with 

 a light band above the angle, darker beneath, gibbous

This weU-knomi species is found not unfrequcntly of 

 larger dimensions than the specimen here figured.

lique promiscuous white and straw-coloured streaks ; 

 whorls four to five, rather flattened, the last suddenly 

 deflected anteriorly, granular at the base ; aperture 

 nearly horizontal, narrow, oral, fulvous within ; lip 

 funnel-like, with the margins sharp and continuous, 

 columellar margin inwardly dilated, thickened, broadly 

 toothed. 



Hab. West Indies ? 



Bemarkably characterized by its oval continuous aper- 

 ture, and pretty white streaked pattern.

Thr punctured Helix. Shell imperforated, conoidly 

 globose, solid, obliquely plicately striated in the an- 

 terior direction, dark chestnut, encircled with a faint 

 thin zone : spire obtusely conoid : whorls five to sis,

 margins joined by a broad callosity armed with a

Hab. Martinique. 



The plicated sculpture of this species is peculiar in run- 

 ning in the anterior direction, the reverse of that which 

 marks the growth of a shell. Its great columcUar tooth b 

 also remarkable.
