80 MOLLUSCA OF SOMERSET. 
ERRONEOUS RECORDS. 
THE author of the article on Mollusca in the Victorian History 
of Somerset (1, 71) writes :—“ Amongst records which cannot 
be accepted are those of Vertigo substriata, V. alpestris, Suc- 
einea oblonga, and Assiminea grayana. The last-named form 
is strictly confined to the Thames estuary, and its occurrence 
in a Somerset list must be due to a mis-identification. Sweeimea 
oblonga has only been doubtfully recognised amongst rejecta- 
menta of the Brue, and if correct the specimen probably came 
from a Pleistocene deposit. Vertigo substriata is a mistaken 
identification of Miller’s record of Turbo sexdentatus, which is 
Vertigo antivertigo, while V. angustior comes from a Glouces- 
tershire locality.” 
If V. angustior is to be excluded on those grounds then we 
must also leave out V. pusilla, for both were obtamed by 
Gwyn Jeftreys from rejectamenta of the Avon at Bristol. 
Certainly Vertigo substriata must be omitted. Through care- 
lessness in not carefully looking up the record, I gave this 
species a place in my paper on Somerset Mollusca in the 
Journal of Conchology. For note concerning Succinea oblonga 
see p. 44. 
Assiminea grayana is recorded for the Weston district by 
Mr. Francis Knight, and appears in many of the old lists of 
Somerset mollusca. Apparently Leipner was the first to assert 
that this species occurs in the Somerset Avon (see his list in 
which he gives it for ditches at Avonmouth). Cundall thought 
its inclusion to have been “in all probability the result of 
accident or error.” I wrote to Mr. Knight about the Weston 
record and he replied: ** With reference to Assiminea grayana, 
which I notice you do not admit except from the Thames, I 
had specimens from the shore at Uphill which were identified 
by a good conchologist, the late William Robinson, who, by 
the way, certainly obtained them elsewhere than the Thames 
estuary.” Ina further communication he remarked: “ My re- 
puted Uphill ones have not survived, and it will probably be 
wise not to accept them without more confidence.” All the 
evidence is against the occurrence of this species in the West. 
It must be excluded. 
A very curious Arion, which I found on a lawn at Wains- 
grove, Grosvenor Square, Southampton, was figured and de- 
scribed by W. E. Collinge as a new species under the name of 
Arion elongatus, in the Annals and Mag. of Nat. Hist., 1894,
