CARDITA, 
Gen. Char. An inequilateral equal valved bivalve* 
with recurved beaks; hinge teeth two, unequal, 
the shortest beneath the beaks ; the lateral one 
longitudinal, beneath the insertion of the car- 
tilage. 
CARDITA striata* 
TAB, LXXXIX.— Fig. 1. 
Spec. Char. Quadrangular, gibbous; the beaks 
placed at one of the angles ; obliquely striated 
from the beaks to the edge." 
Nearly right-angled ; the anterior side rounded; the 
length greater than the width : the striae are curvilinear. 
This is from Swanswick in Somersetshire, by favor of the 
Rev. H. Steinhauer; it is in ochraceous Limestone with a 
sandy aspect. It appears to be the cast from the mould of 
the outside of the shells. Walcot’s ( Bath Fossils) Fig. 11, 
probably belongs to this species; he observes, u at one of 
the angles are the beaks which are hooked, their points 
curved outwards; striated from the beaks to the margin,,
