HELIX. 69 



H. virgata. It is found on sand-hills near the sea in 

 South Wales, Cornwall, Dublin, and Jersey. 



In the south of France and in Italy it is collected in 

 great quantities for food, and may be seen exposed for 

 sale in the markets. In Marseilles and Venice I have 

 seen this species in countless thousands adhering to 

 nettles and other plants, apparently enjoying the noon- 

 day sun. 



Var. alba. White or pale yellow. 



16. H. VIRGATA (striped). 



Conical, globose, solid, almost opaque, cream-coloured, 

 very variously banded ; whorls six, tumid ; spire raised ; 

 mouth nearly circular, furnished with an internal lip of & 

 pinkish colour ; umbilicus narrow, but deep. 



This very variable shell is found on downs and sand- 

 hills in many parts of the British Isles but not in 

 Scotland especially near the sea coast. It is exceed- 

 ingly abundant in most places where it occurs, and as 

 it varies greatly in size, colour, and markings, a good 

 series ought to be secured. 



The young are carinated. 



Var. I. subaperta. Whitish, depressed, umbilicus 

 very wide. 



Var. II. subglobosa. Smaller, with a double band 

 above the periphery; umbilicus wide.
