Hah. Southern Europe. North Africa. Canary Isles and Azores. West 

 of England, south-east of Ireland and Jersey. (In fields and on sand- 

 hills near the sea.) 



Helix Pisana would seem to be rather an intruder in the British 

 fauna. It has only been found in Cornwall and South Wales, in the 

 south-east of Ireland and in Jersey. Its native home is in Italy 

 and the south of France, Spain, Portugal, and North Africa. In 

 Spain it is the common snail of the country. In the north of 

 France and in Germany, the species is unknown. The animal is 

 yellowish-grey, purplish towards the head, and the shell is cream- 

 coloured buff, banded with interrupted pencillings of black or brown 

 and sometimes tinged about the aperture and body-whorl with rose. 

 Mr. Jeffreys has remarked that the more sheltered the place it in- 

 habits, the less rosy the shell is ; and Dr. Gray deduces from this 

 observation, that the animal thrives better in sunny places, as being 

 most like the warmer climate which is its more natural temperature. 



8. Helix virgata. Striped Helix. 



Shell ; moderately umbilicated, subglobosely turbinated, rather 

 thin, dead white or buff- tinted, variously en- 

 circled with rust-brown bands and lines, spire 

 somewhat raised, horny at the apex, whorls 

 five and a half to six, slopingly rounded, 

 sometimes obtusely keeled at the periphery, 

 closely rather roughly arcuately striated ; aper- 

 ture lunar-rounded, lip simple, strongly inter- 

 nally ribbed, tinged with flesh-pink, columellar 

 margin dilated partly round the circumference 

 of the umbilicus.
