23. H. CAPERATA (wrinkled), Montagu. P\. III., f. 13. 
Sub-conical, compressed, solid, opaque, dull, dirty white, streaked 
and banded by variable lines which are sometimes merely a row of 
spots, strongly and regularly striated, obtusely carinated ; whov/s 6; 
mouth nearly round, furnished with a white internal rib ; zezdzZ¢cus 
open and shallow. A. 53mm. B. Io mm. 
Found under stones and on the stalks of grass on sandy 
soils, especially near the sea coast, where it is sometimes 
almost as abundant as the last species, and frequently 
found with it. It is also common in many parts of 
Ireland, and throughout Great Britain as far north as 
‘Sutherlandshire. 
It is a particularly hardy animal, and will often be found 
feeding in winter when other snails are torpid. “It has as 
great a power of enduring heat as cold, and I have 
observed it not only in many parts of southern Europe, 
but even on the desert in the neighbourhood of Bagdad. 
It is, perhaps, apt to be confounded with the young of 
HZ, virgata, which are also carinated ; but a very little ex- 
perience will enable the collector to determine its identity. 
It is usually smaller and more depressed and has a 
larger umbilicus than the adult of the last species ; but 
the diagnostic character is the close regular striation of 
ff, caperata, which should be compared under a lens 
with the coarse striation of H. virgata. 
The forms dzzonalts and obliterata are rare, the latter 
corresponding with the white forms with translucent bands 
of H. virgata and H. ttala.
