10 MOLLUSCA OF SOMERSET. 
South. 
Brympton, a damp spot in the Park ; J. Ponsonby. 
ZONITOIDES EXCAVATUS, Bean ( = Hyalinia excavata Wester- 
lund and Zonites excavatus Gray ). 
Under decaying wood and leaves often in company with the 
ubiquitous Pyramidula rotundata. Taylor remarks of it 
(Monograph, 111, p. 1387), “a species that has probably been 
misunderstood and overlooked on the continent, as it is very 
unlikely to be so strictly confined to the limits of the British 
Isles, as its recorded distribution would indicate.” The only 
extra British localities at present known are Esschen, near 
Antwerp, and Flensburg in Schleswig. Distribution sporadic 
in the British Isles. It is rare in Somerset. 
North. 
Pylle; F. N. Townsend, 1856, Haslemere Mus. Coll. 
Under loose stones outside the camp on Worlebury, 
Weston-super-Mare ; Ff. A. Knight. 
Weston Wood ! 
South. 
Dulverton ; HZ. Watson. 
Var. vitrina, Férussae. 
Dulverton ; Hugh Watson. 
Evconuuus FruLvus, Miller (= Hyalinia fulva, Morch, and 
Zonites fulvus, Jeffreys). 
Generally distributed, chiefly found under rotting sticks in 
damp situations. 
Var. Mortoni, Jeffreys. Recorded by Jeffreys in British 
Conchology, 1862, p. 171, from Somerset, but without 
locality. It is possible that the “small” specimens 
found by Norman on Elton Hill, Clevedon, and among 
rushes in Walton Moor, come under this heading. 
(There may be seen in the Bath Museum a single speci- 
men of a fossil species of Hyalinia, found by Mr. Moore 
in a bed of lias clay twelve feet in thickness, at a 
depth of 270 feet, in the Charter House lead mines in 
the Mendips. It is a minute species, less than one 
millimetre in diameter. Moore described it under the 
name of Helix Dawsoni in Quar. Jour. Geol. Soc., 1867, 
p. 549, pt. xv, f. 12].
