Proceedings : march 9, 1898. 57 



By Mr. J. Madison: Sphmrium corneum var. scaldiana from Worcester Canal 

 Reservoirs, Cofton. 



By Mr. A. G. Stubbs: Saxicava rugosa, and var. pholadis from Giltar, Tenby; 

 and Thracia papyracea from Pendine ; also a remarkable series of Planorbis spirorbis, 

 in four boxes — {a) extremely large and perfect normal types ; [b) a series of over 20 

 specimens showing angular compression and a general tendency towards distortion ; 

 (c) twenty-eight examples showing extraordinary contortion, chiefly in the last 

 whorl, which is in many cases separated from the rest (subscalariform), and in 

 several is curled round either base or apex of shell in a sort of knot ; some specimens 

 have begun in a subscalariform manner, and finished quite normally, these present 

 the appearance of a small table; (<•/) twenty-four specimens, truly scalariform, 

 varying from a simple coil, more or less regular, to a perfect "corkscrew"' form. 

 All these specimens, which undoubtedly present the most remarkable assemblage of 

 distorted shells ever shown at a meeting of the Society, were taken in Black Rock 

 Stream, Tenby, in 1897-8. 



By Mr. L. E. Adams : An album formerly belonging to the late Mr. A. Adams, 

 and containing a large number of autographs of eminent British and Foreign 

 Conchologists. 



By Mr. W. Moss : A number of Hyalinitz from Anglesea and elsewhere, upon 

 which he made some remarks which gave rise to an animated discussion. Mr. 

 Moss further expressed the hope that any members who might have an opportunity 

 of procuring living Hyalinia glaber or Hy. draparnandi during the season, would 

 send him specimens either alive or in spirit for dissection.
