TAB. CCXIV.---Fig. 1. 
SPEc. Cuar. Obovate, oblique, with seven longi- 
tudinal costz ; anterior ear open, with thick- 
ened lobes. 
SomEwHAT longer than wide ; the surface is convex ; the 
coste are large and rugged: one of the ears is small; 
the other long, with thick and reflected edges to its 
valves. 
This is a rugged specimen of apparently a rugged 
shell; it was picked up by my good friend Mrs. Gent, 
at Calne.

LIMA antiquata. 
TAB. CCX1V.—Fig. 2. 
Spec. Car. Elliptical, depressed, coarsely striated ; 
anterior ear deeply wrinkled, open. 
Tae striz are numerous, close, irregular, and ragged 
towards the margin: the width is about two-thirds the 
length. The smaller ear is striated like the rest of the 
shell, and closed. 
The shell from which this is taken belongs to Mr. 
Miller; it was found in the Lias at Frethern, in Glouces- 
tershire.
