HELIN: 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. vireAra (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 a 
pinkish colour ; wmbilicus 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 1s 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. sudglobosa. Smaller, with a double band 
above the periphery; umbilicus wide.
