TELLINA obtusa. 
TAB. CLXXIX.—Fig. 4. 
Spec. Cuar. Transversely ovate, convex, con- 
centrically striated ; margin obtuse ; sides very 
unequal. 
Tur wave upon the anterior side that distinguishes the 
Genus Tellina, is very slight in this. The surface is most 
rapidly curved near the edge, which being obtusely oval, 
the whole has a blunt clumsy appearance; the striz are 
concave, wide, and numerous. The anterior side is much 
the smallest. Young shells are flatter and less rounded 
towards the margin. 
My friend, the Rev. P. Lathbury, first sent me this 
species of Tellina, from the Crag near Woodinidao; 
about twenty years ago: I have since received it from 
Roydon, by favour of the Rev. G. R. Leathes, and have 
found it at Bramerton in abundance.
