Shell white, pellucid, smooth, glossy ; body occupying about 
half the length of the shell ; spire taper, consisting of five nearly 
flat -sided volutions, well defined by the suture; aperture 
oblong-ovate, subtruncated at the base ; outer lip thin, even ; 
pillar lip thickened, and a little reflected on the columella. 
Length a quarter of an inch ; and hardly a fourth of its length 
in diameter. 
This species is not uncommon in many parts of Great Britain 
and Ireland. It inhabits the roots of grass and trees, especially 
where there are limestone rocks ; plentiful in Barham Downs, 
Kent; Lackham, Wiltshire; and at Miltown Malbay, in the 
neighbourhood of Dublin ; La Bergerie, Queen’s County ; 
Castle Martyr, near Cork; and at Dromana, County of Water- 
ford, by Miss M. Ball of Dublin. 
Genus 47 — Bulimus. — Lamarck. 
Shell oval, or oblong, generally thin, and covered with a 
slender epidermis ; spire obtuse, variable in length, and in the 
number of its volutions, which for the most part are few ; aper- 
ture oval, wide, anteriorly rounded ; outer lip simple, reflected, 
continuous, and joining the columella without an emargination ; 
columella smooth, straight, without a truncature, or widening at 
the base.

Variety a, pi. XIV, f. 21. 
Shell subcylindrical, subconic, of an opaque brownish horn- 
colour ; body not half the length of the shell ; spire consisting 
of five or six somewhat inflated volutions, well defined by the 
suture, covered with longitudinal slight substrise, or wrinkles, 
and terminating in a rather obtuse apex; aperture oblong-oval; 
outer lip even, and white; inner lip white, and reflected on the 
columella, with a slight subumbilicus behind. Length three- 
eighths of an inch ; diameter one-third its length. 
[Trachelipoda 
The young shell is conical, or pyramidal, and in the very 
early stages trochiform ; with the aperture subquadrangular. 
This species can only be distinguished from the B. montanus 
by its inferior size, its white lip, and in its volutions being some- 
what more inflated. 
Found amongst moss in moist places, under stones, and on 
old walls, and also on rocks; in which last locality we found 
some fine specimens near Sunderland. 
I found a very distinct variety of this species in the limestone 
quarry on the top of the East Lomond hill, Fifeshire, and 
named it B. brevis, pi. XIV, f. 21. It differs from the ordinary 
variety in being much shorter, and greatly more inflated in pro- 
portion to its size, with the apex more acute.

Ib., Ency. Brit., 6th Ed., VI, p. 461 ; Maton and Rackett, 
Linn. Tr., VIII, p. 212. 
Shell subconic, oblong, of a dull rusty or reddish-brown, 
longitudinally, obliquely, and irregularly wrinkled, or striated, 
somewhat like shagreen when viewed through a strong lens; 
body a little more than a third of the shell in length ; spire 
consisting of six nearly flat-sided volutions, well divided by the 
suture line, terminating in a rather obtuse apex ; aperture 
subovate ; outer lip reflected, and of a chocolate-brown colour ; 
pillar lip reflected on the columella, forming a subumbilicus 
behind it. Length somewhat more than five-eighths of an 
inch ; and a quarter of an inch in diameter. 
Found at Lackham, in Wiltshire, by Colonel Montagu ; met 
with sparingly in the debris of Salisbury Crags, at Edinburgh ; 
and I found it at Castle Willan, near Maryborough, Queen’s 
County ; and in the debris of the mountains of Mourne, 
Ireland. 
The young shells of this, like those of the preceding species, 
are trochiform ; and the adult is liable to considerable variety 
in colour.
