To English collectors, this pretty wrinkle-striated Helix is best 

 known by the name of caperata. Montagu was the first to give a 

 figure of it ; but M. Moquin-Tandon has satisfactorily shown that 

 Poiret's H. fasciolata can be no other than this species, and his 

 name takes precedence. It is a smaller shell than H. virgata, more 

 depressly convoluted, and the spiral bands are more frequently in- 

 terrupted. The whorls are narrower, and they form a larger umbi- 

 licus ; the principal specific character is, however, the close sculp- 

 ture of oblique rib-like striae, which is the same in all, whatever 

 may be the variety of painting. The animal is of a silvery grey, 

 streaked and stained about the neck and head with brown. Its 

 range of habitation, like the preceding species, extends from Central 

 Europe to North Africa, but it is less abundant.
