Mr. K D. Daebyshire, F.G.S., exhibited specimens of the 
rare bivalve mollusc Panopsea Aldrovandi, from Faro Island, 
Algarve, S. Portugal, a species almost confined to this iso- 
lated locality. He also exhibited, for sake of comparison, 
specimens of the British Panopsea Norvegica and various 
Saxicavse, and sketched the distribution of the six species 
comprised in the genus Panopsea, the range being a remark- 
ably wide one. 
Dr. Alcock read a paper on Lagena striata and its allies, 
and exhibited many beautiful drawings illustrative of this 
genus of foraminifera. 
Mr. Linton distributed specimens of Helix lapicida (L.) 
from Matlock, Derbyshire.
