82 MOLLUSCA OF SOMERSET. 
ADDENDA. 
Mr. H. L. F. GuERMonpPREz, of Bognor, writes :—“ 1 find a 
list of Mollusca in a Clevedon Guide, copied from the Clevedon 
Mercury by Miss Lily Grey. It enumerates— 
Bithynia tentaculata, ditches. 
Planorbis corneus.

The list is noteworthy in one particular, viz., the record of 
Hygromia revelata for Somerset. This is a Lusitanian species 
occurring only (as far as Great Britain is concerned) in Devon 
and Cornwall. Wishing to obtain confirmation of the record 
1 wrote to the Editor of the Clevedon Mercury, who replied : 
“The Helix revelata is mentioned in a Clevedon Guide pub- 
lished 30 years ago, the writer of which has been dead for 
some considerable time. Presumably ‘ Lily Grey,’ who com- 
municated this information to the Clevedon Mercury previous 
to that date, is dead also. Anyway we do not know her present 
address.” It is probable that the shell in question was Hy- 
gromia fusca, for it is very unlikely that H. revelata occurs in 
North Somerset.
