more curved than the opposite ; cardinal teeth 
small, lateral teeth more than one-third the 
length of the long fulcra.

Jb rom Solen siliqua , Linn., our shell differs in its propor- 
tional width, which is much less, and in its greater degree 
of convexity; also in the absence of an angle separating the 
upper edge of the posterior area ; from Solen Ensis, Linn., 
Ensis magnus , Schum., in having only half the proportional 
width. 
From the coralline Crag of Ramsholt, and the red Crag 
of Walton Naze. 
ENSIS complanatus. 
TAB. DCXLII. — -Jigs. 2, 3 and 4. 
Spec. Char. Slightly curved, strong, smooth, 
compressed, anterior side shortest, angles 
rounded. Anterior hinge-tooth large, lateral 
teeth less than one-third the length of the long 
fulcra.

Mag. Nat. Hist. v. vi. 245. 
The regular very slight convexity, less width, and the 
want of an angle to separate the posterior area from the 
hinge -slope, are marks by which this species is known 
from the recent Ensis siliqua. 
Found at Sutton in the red, and at Bramerton in the 
mammiferous Crag. The specimens figured were in the 
late Mr. Parkinson’s collection.
