VENERICARDIA carinata. 
TAB. CCLIX.--- Fig. 2. 
Spec. Cuar. Transversely oblong, with 20 nearly 
smooth carinated ribs ; lunette obsolete. 
A azsose rather slender shell, but little indented 
below the beaks; the ribs are prominent, and rather 
square, with a sharp elevated smooth keel along each ; 
the lunette is minute; the edges are toothed as usual. 
Width about one inch, and length 3-4ths of an inch. 
This elegant species was procured by J. Holloway, 
Esq. at Stubbington. 
VENERICARDIA deltoidea. 
TAB. GGLIX,+--Fig.) 1. 
Spec. Cuar. Deltoid, with rounded angles; ribs 
15, keel formed ; hinge callous; beaks pro- 
minent ; lunette small. 
A rarnee strong shell, particularly heavy about the 
beaks ; the ribs rise very gradually from the surface of 
the shell, and are sharp in the middle, they are smooth ; 
the edge is toothed between the ribs. 
A remarkable shell, found by C. Lyell, Jun. Esq. in 
clay, at Lyndhurst in Hampshire, 
TAB. CCLIX.---Fig. 3. 
Ts the cast of a shell nearly allied to a Venericardia, 
but too imperfect to decide upon; it is of rare occur- 
rence in the Marl of Ringmer, whence G. Mantell, Esq. 
sent it. I should be happy to meet with better.
