CLAUSILIIDA. 4] 
North. 
“ At Bath and Bristol, under ash boughs that have lain 
long on the ground”; Jeffreys. 
Rejectamenta of the Avon; Jeffreys, 1833. 
Rejectamenta of the stream at Shepton Montague, below 
the Rectory, abundant ! 
Weston Wood ! 
VERTIGO PYGMHA, Draparnaud. 
This is probably the commonest representative of the genus, 
usually occurring under sticks and bark in damp situations. 
North. 
At roots of grass, under sticks and stones, Bratton St. 
Maur ; also extremely abundant in rejectamenta of the 
streams in the Wincanton district ! 
Abundant in Weston Wood and in Brue drift; F. A.

Bath; Jenyns Coll., Bath Museum. 
South. 
Yeovil, near Sutton, Brympton; J. Ponsonby. 
Triscombe Stone; WV. G. Hadden. 
Var. quadridentata, Studer. 
Clevedon ; Norman. 
VERTIGO PUSILLA, Muller. 
Apparently very rare. There is only one record. Gwyn 
Jeffreys found it, in 1833, in rejectamenta from the Avon, 
near Bristol. 
VERTIGO AUGUSTIOR, Jeffreys. 
Another very rare species, found by Jeffreys im the Avon 
rejectamenta (see British Conchology I, 266). In the pre- 
fatory remarks to his list of Somerset non-marine Mollusca 
in the Victoria History of Somerset, B. B. Woodward re- 
marks that this record cannot be accepted, as it “comes from 
a Gloucestershire locality,” yet he includes it in his list! If it 
is to be excluded on these grounds, so must V’. pusilla, for both 
were recorded by that eminent conchologist, Gwyn Jeftreys, 
from rejectamenta of the Bristol Avon.
