1 he peculiar folds of the margin on both sides the umbo 
of the right valve produce corresponding sinuses on the 
edge of the left valve, as may be most distinctly seen when 
the valves are together. There are two teeth in the left 
valve, that nearest the beak being placed longitudinally ; 
the other is almost at right angles with it and is produced 
along the hinge-line. The pit for the ligament is elongated, 
small, and under the posterior portion of the hinge-line. 
The muscular impressions are large. 
An abundant shell in the coralline Crag at Sutton, but 
rarely found with the valves united. It is living on the 
coast of Sicily.
