VALLONIA EXCENTRICA, Sterhki. 
Closely allied to V. pulchella, differing chiefly in the excentric 
and somewhat elongated umbilicus. (See British Non-Marine 
Mollusca, pp. 42-43). It occurs in similar situations, and is 
probably equally widely distributed.

Specimens of this interesting variety taken from a stone 
wall near Wells were exhibited by the Rev. S. Spencer 
Pearce at the meeting of the Conch. Soc., July 7th, 
1887. Ina note in the Journal of Conchology (p. 255) 
of the same year Mr. Pearce stated that they occurred 
‘on a loose ivy-coloured stone wall on the old Bristol 
road, just outside the city. The variety is associated 
in this place with individuals of a brown form. The 
pale brown specimens are the most frequent. It is easy 
indeed to arrange a complete series which will show 
every variation in colour from the dark-brown to the 
purest white. The wall on which this variety flourishes 
is composed of rough blocks of liassic limestone taken 
from a small pit close at hand.”
