10. Voluta triplicata. Three-folded Volute. 
Donovan , pi. 138. 
Shell strong, oval, smooth, chesnut-brown : spires six, 
the first occupying three-fourths of the shell, the volutions 
so very flat as to be distinguished by the separating line 
only: aperture contracted; pillar with three folds : length 
hardly an inch ; breadth a third of its length. 
It resembles V. denticulata, but is stronger and more 
opake, the volutions much flatter, and it wants the inner 
denticles on the pillar. 
On the shores of Guernsey: rare. 
11. Voluta bidentata. Two-toothed Volute. 
Montagu, pi. 30. f. 2. 
Shell conic, pointed, strong, thick, pure white and some¬ 
what glossy : spires six or seven, with a few distant longi¬ 
tudinal wrinkles which give an undulated appearance to the 
separating line ; the first volution extending over two-thirds 
of the shell: aperture narrow, contracted at the upper part; 
t\\e outer-lip thick ; pillar much thickened, reflected and 
forming a slight perforation, and furnished with two tooth¬ 
like folds : length a quarter of an inch : breadth a third of 
its length. 
In the thick outer-lip and small perforation behind the 
pillar it resembles the V. reflexa; but differs in color, in 
the flatness and number of the volutions, in being of a more 
conic form, and in having no teeth on the outer-lip and 
fewer on the pillar : and from V. alba it is distinguished by 
the thick outer-lip, and the reflected pillar-lip. 
Coasts of Dunbar and Devonshire, v. m. 
12. Voluta hyalina. Transparent Volute. 
Montagu , pi. 30. f. 1.

.spires six, flat and hardly defined by the separating line ; 
the larger volution covering more than half the shell: aper¬ 
ture contracted into a kind of lip or canal, and is abruptly 
cut off at the end; pillar with seven or eight fine thread¬ 
like folds : length a quarter of an inch ; breadth more than, 
a third of its length. 
On the Dunbar coast: very rare.
