and the pillar has three or four much elevated white folds. 

 Mr. Montagu says that the pillar extends no further than the 

 upper part of the body-whirl, and that the spire is conse- 

 quently destitute of any internal spiral division. 



triplicata. 19. Shell ovate, smooth, with the spire 

 elevated; aperture narrow, contracted; pillar 

 with three teeth.

 p. 99- 



Inhabits Guernsey. Montagu. 



Shell scarcely half an inch long, and half as broad ; of a chest- 

 nut-brown colour, with six whirls, of which the first occu- 

 pies three fourths of the whole, aud the others are marked 

 only by the suture. The pillar being three-toothed, and its 

 more contracted aperture will serve to distinguish this from 

 the foregoing species. 



pusilla. 20. Shell ovate, striated, with the spire 

 elevated ; pillar with three teeth.

This shell is of the same size, and has much the same appear- 

 ance, as 1^. triplicata, but Martini has described it to be 

 striated perpendicularly, and the aperture is represented 

 wider and less contracted iu the upper part. 



bidentata. 21. Shell ovate, slightly wrinkled 

 longitudinally ; spire elevated, conical ; pil- 

 lar with two teeth. 



Voluta bidentata. Montagu Supp. p. 100. t. 30. f. 2. 



Inhabits the coasts of Scotland. Mr. Laskey ; and of Devon- 

 shire. Montagu. 



Shell a quarter of an inch long, and about half as broad ; thick, 

 white or pale horn-colour, with a few distant longitudinal 

 wrinkles. Pillar much thickened, and folding back forms 

 a sub-umbilicus, and is furnished with two tooth-like plaits. 

 Its smaller size, and not having any teeth on the outer lip, 

 will serve at once to distinguish this species from V. denticu- 

 lata.
