19. H. REVELATA (discovered), Michaud. PI. TEL. £9: 
Somewhat globular ; sve depressed ; pale olive-green, covered 
scantily with short pale hairs ; zhor/s 4—43; suture deep 3 *o2th 
nearly circular ; zsedzZicus small. A. 5mm. B. 8mm. 
This is a very local species, and not abundant where it 
occurs. Jeffreys says “In winter and dry weather it 
buries itself rather deep in the earth, and must be looked 
for by pulling up tufts of grass and large stones which are 
sunk in the ground, as well as by searching among the 
roots of shrubs and furze-bushes.” 
Its British range is restricted to the Channel Isles, 
Cornwall, and South Devon. Jeffreys also gives Notts. 
as a locality, but this does not seem to have been con- 
firmed. 
20. H. Fusca (dusky brown), Montagu. YI. III. ETO: 
Sub-conical, so thin as to be almost membranaceous, glossy, pale 
yellowish brown, strongly striated in the line of growth ; very faintly 
keeled 5 whorls 5—5% 5 wmbilicus very small. A. 5smm. B. 83mm. 
The shell of this species is almost membranaceous, and 
I have known it to collapse when the animal has been 
extracted, and to be blown up again without injury. It is 
difficult to extract the animal entire. 
Though local it is sometimes abundant. Its range 
extends interruptedly throughout Great Britain from 
Devon to Sutherlandshire, and it also occurs in many 
parts of Ireland.
