TEREBRATULA serrata. 
TAB. Dill. — -jig. 2. 
Spec. Char. Rounded, triangular, convex with a 
blunt margin, largely plaited ; beak small, with 
a large nearly flat space on each side of it ; 
plaits sharp, about 11, of which 5 are a little 
raised in the front. 
This is more depressed than the shell above referred to 
in the Encyclopedic, but in other respects much like it. 
Can it be a young individual of the same species ? 
From the same collection as the last : found in Eyas 
at Lyme Regis.
