The bell-like Helix. Shell lunbilicatcd, globoscly 

 conoid, solid, obliquely finely striated, very finely 

 sculptured with close-set spiral lines, sliiniiig, white 

 or pale straw-colour, encircled with one or two chest- 

 nut bands ; spire bell-shaped, rather obtuse at the 

 apex ; whorls five to six, slightly convex, the last 

 descending in front, gilibosely constricted at the base 

 next the aperture ; aperture oblique, somewhat

squarely rounded; lip thickened, rcfl.cted, margin!' 

 nearly apprcximatcd, joined by a shining calloKit), 

 columellar margin furnished inwardly with a tooth- 

 like protuberance, dilated outwardly, open, sinuous. 



Pfeiffer, Pro. Zool. Soc. 1840, p. 112. 



Uab. Island of Nicobar ; T. Pliibppi. 



The aperture of this species is characterized by a 



strongly reflected callous lip, dilated over the umbilicus, 



where it is furnished with a tooth-like protuberance.
