VENERICARDIA carinata. 
TAB. CCLT X.—Fig. 2. 
Spec. Char. Transversely oblong with 20 nearly 
smooth carinated ribs ; lunette obsolete. 
A gibbose 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. CCLIX. — Fig. l. 
Spec. Char. Deltoid, with rounded angles ; ribs 
15, keel formed; hinge callous; beaks pro- 
minent ; lunette small. 
A rather 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. 
Is the cast of a shell nearly allied to a Yenericardia, 
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.
