PsAMMOBiA VESPERTINA, Chemnitz. The Setting 
Sun. — ^Shell of an oblong oval shape, equivalve, rather 
flattened, opaque ; colour whitish, shading to a reddish- 
yellow at the beaks, with radiating rays of carmine and 
purplish-pink ; epidermis of an olivaceous brown; liga- 
ment external, prominent, and of a horn-colour ; beaks 
small ; teeth, two in each valve ; in the left valve, one 
tooth bifid.

country, though several kinds are used for that purpose 
abroad. With us, the Psammobia vespertina is stated 
by Mr. Jeffreys* to be eaten by the peasantry at Ken- 
mare, and heaps of their shells may be seen round the 
huts.
