RECORDS OF SOMERSET MOLLUSCA. 
THE arrangement here followed is that of the latest lists 
published by the Conchological Society. The great changes 
in nomenclature which have recently taken place necessitate 
the inclusion of numerous synonyms. 
The exclamation mark indicates that the species (or variety) 
has been seen by the author in the locality mentioned. 
All records of varieties are included, but the recorded 
stations of species, which there is every reason to think are 
generally distributed in the county, have been omitted. 
Collections of Somerset shells in the Museums at Bristol, 
Bath, Sexey’s School, Bruton, and Haslemere (Surrey), have 
been examined during the preparation of these records, also 
private collections formed by the late Mr. Kenneth McKean 
(Bath), and Mr. William Herridge (Torquay), 
LAND AND FRESH-WATER. 
The latest list of British non-marine mollusca published by 
the Conchological Society enumerates 170 species (inclusive 
of brackish-water forms). Ten of these are aliens, and sixteen 
occur only in a fossil state in Post-Pliocene deposits, leaving 
a total of 144 native species living in Britain at the present 
time. The following pages contain records of no less than 122 
species, a very high percentage indeed. Ninety-five are 
recorded from the southern, and 121 from the northern 
division. The only species recorded from South Somerset 
alone is Amphipeplea glutinosa. In all probability Hygromia 
revelata, Férussac; Vertigo moulinsiana, Dupuy; Vertigo 
substriata, Jeffreys; and Segmentina nitida, Miller, will be 
added to the list within the next few years, all have been 
found in neighbouring counties. 
TESTACELLIDEA. 
TESTACELLA MAUGEI, Férussac. 
According to Norman this species was observed in nursery 
grounds at Clifton (Glos.) in 1814. “ From that time to the 
present (7c. 1860) it has thriven and propagated freely in its
