SOLfeN Dixoni. 
TAB. DCXLI.— -fig. 3. 
Spec. Char. Four and a half times as wide as 
long, straight, regularly convex, smooth ; an- 
terior side very slightly oblique, its furrow 
rather distant; posterior extremity rounded ; 
fulcrum very long. 
We have great pleasure in dedicating this new species to 
F. Dixon, Esq. of Worthing, whose forthcoming work on 
the Tertiary and Chalk formations of Sussex will bear 
ample testimony to his zeal and perseverance in bringing 
to light a great number of new and interesting fossils. The 
species before us resembles very much the S. •vaginalis , 
Desh., which is found at Grignon, but that is a thinner 
shell and has a much shorter fulcrum.
