ing the long damp grass in woods and shady places with 
a butterfly net. 
37. H. fusca seems to be chiefly confined to the High¬ 
land districts of the county, where it is found in shady 
glens. It has been taken in Glen Farg and Glen Tilt, 
and at Dunkeld and Pitlochry. The shell is extremely 
fragile and transparent, and may be mistaken for a very 
young specimen of H. nemoralis. 
38. H. rotundata is the most abundant of the genus, and 
is distributed throughout the district. It is partial to dry 
situations, such as stone heaps and old walls, and is at 
once recognised by its strongly-marked strife. I have 
taken the variety pramidalis in Quarry Mill Den, and 
the variety alba at Pitlochry. The latter variety has also 
been found by Dr Buchanan White on Kinnoull Hill. 
39. H. rupestris is a rare shell in Scotland, and in Perth¬ 
shire has only, I think, been found on Kinnoull and 
Moncreiffe Hills, where it is not uncommon on the cliffs. 
40. S. pygmcea is the smallest of our land mollusca, being 
not larger than the head of the smallest pin, and about the 
same shape. Being morever of an earth-brown colour, 
it will be understood that this species is not in danger of 
being exterminated by the ruthless collector! It is widely 
distributed, and a careful search amongst decaying leaves 
or loose stones in suitable situations will generally be re¬ 
warded by a few specimens. 
41. E. pulchella is well named the “beautiful snail,” for 
its tiny white shell is ornamented with a porcelain-like 
ring surrounding the mouth, and, in the variety costata, 
with radiating ridges, caused by folds of the epidermis. 
It is found on Moncreiffe and Kinnoull Hills, but is not 
common. All the specimens I have taken myself appear 
to belong to the variety costata. 
42. Bulimus obscurus. This genus and the remain¬ 
ing genera are distinguished from the preceding ones 
by having the spire prolonged so as to give the shell a 
cylindrical form. The present species is common both in 
the Lowland and Highland districts, and is found in dry 
situations, such as stone heaps and grassy banks. 
43. Pupa umbilicata. This little mollusc is generally 
found in company with the last, with which it has an 
equally wide range. Immature specimens of both of 
these shells are so unlike mature specimens as to be puz¬ 
zling at first sight, but in such cases the texture of the 
shell is the best guide. 
44. Pupa marginata. Dr Buchanan White informs me 
that he has taken this species on Kinnoull Hill. The 
shell is very similar to that of the preceding species, but 
the lip is rounder, and strengthened by an outer white 
rib. 
45. Vertigo substriata is not uncommon amongst stones 
and long grass, but is probably often overlooked on ac¬ 
count of its minute size. 
46. V. edentula is found in similar situations to the last, 
but is more widely distributed. 46.* V. antivertigo has 
been taken by Dr Buchanan White in damp places at 
Quarry Mill. 
47. Balia perversa is rather local, but not uncommon 
where it does occur. It is found on rocks and old walls 
on Moncreiffe and Kinnoull Hills, and has been taken by 
Dr Buchanan White at Dunkeld. 
48. Clausilia rugosa, though much more abundant 
than the last, is also rather local. It is the commonest 
species on Kinnoull Hill, where it abounds, not only on the 
cliffs, but frequently on the trunks of the trees. Rocks 
form its favourite habitat. The varieties tumidula and 
Everetti are not uncommon. 
49. O. laminata is the rarest of our local mollusca, for 
one rock in the neighbourhood of Perth is the only sta¬ 
tion in which in has yet been taken in Scotland, and even 
there it is not abundant. It was discovered here by Dr 
Buchanan White, in whose name it is recorded in the 
appendix to Jeffrey’s British Conchology. 
50. Cochlicopa lubrica is widely distributed, both in 
the Lowlands and Highlands of the county. It is found 
amongst moss and stones and in moist situations, and 
is recognised by its very glossy and gracefully-shaped 
shell, which is nearly transparent. The variety lubri- 
coides is not uncommon, and I have taken the variety 
viridula on Kinnoull Hill. 
51. Carychium minimum, though one of the least of 
our land shells, is probably the most beautiful. The shell 
is pearly-white, and exquisitely formed. It is widely dis¬ 
tributed, and found in the same situations as the last. 
The foregoing does not pretend to be a complete list of 
the mollusca which inhabit the ponds, woods, and glens 
of Perthshire; indeed, I have reason to suspect that it 
is far from complete. But it will have done its work if 
it serves in any measure as an inducement to some mem¬ 
bers to visit for themselves the haunts of these creatures, 
and to taste the charm of prying into Nature’s most 
secluded nooks and corners.
