January 19tli, 1899. 



Mr. William Caeeuthees, F.E.S., Vice-President, in the Chair. 



The Minutes of the last Meeting were read and confirmed. 



Messrs. Harold Warren Monington and Oswald Alan Eeade 

 were admitted Fellows of the Society. 



Mr. H. W. Monckton, P.L.S., exhibifed specimens of Mya 

 arenaria, Linn., from Norway. He and Mr. E. S. Herries (Sec. 

 Geol. Soc.) had found a colony of these molluscs living on a sand- 

 flat at the head of the rjferland Fjord, about 80 miles from the 

 open sea and where the water at the surface is fairly fresh. 

 The great snowfield the Sostedal approaches close to the N.W. 

 side of the fjord, and at a level of ouly 3500 ft. to 4000 ft. above 

 it, where glaciers descend into the vallejs at the head of the 

 fjord to within 4 miles of the mud-flat in question. The shells 

 were for the most part small and thin, and this might be due to 

 the freshness or to the coldness of the water, or both. It was 

 remarkable, however, that Mytilns edulis, living in the same 

 locality, was perfectly normal. The causes contributing to 

 arrestation of growth in the MoUusca gave rise to a discussion, 

 in which the Chairman and Mr. Clement Eeid took part, Mr. 

 Monckton replying.
