This shell appears, by Chemnitz's figures, to be eight lines long,

Inhabits the Sea near Southampton. Montagu. 



Shell three-eighths of an inch long, and nearly two-eighths 

 broad, sub-pellucid, and of a pale horn colour ; it has five 

 much rounded whirls, and the summit is moderately pointed, 

 and usually darker ; aperture sub-oval, or rather ear-shaped, 

 with the inner lip much reflected, and forming an angle about 

 the middle, behind which is a narrow umbilicus ; Mr. Mon- 

 tagu adds that it bears some resemblance to Helix fossaria, 

 but besides being a smaller shell, it is essentially different in 

 the aperture. 



VINCTUS. 68. Shell conical, small, smooth, with 

 six rounded whirls, and the summit rather 

 obtuse ; aperture sub-orbicular.

 furnished with a narrow channel, which terminates in a small 

 umbilicus." He adds that it is sometimes of a pale horn-co-
