MYA Pullus. 
TAB. DXXXI.—/ig. 2. 
Spec. Cuar. Transversely ovate and _ striated, 
compressed ; anterior side largest; posterior 
side rather pointed. 
EE 
A smatx slender shell about half as wide as long ; it is 
strongly marked by lines of growth, and therefore ap- 
pears to be a full-grown shell. 
Drawn from a specimen found in Crag at Butley, in 
Suffolk, and which is in the late Mrs. Cobbold’s collec- 
tion. It is said to be the only one met with. It is pos- 
sible it may be the young of M. arenaria tab. 364; but 
the difference of form and the roughness of its surface 
militate against that idea.
