TELLINA striatula. 
TAB. CCCCLV1. —fig, 1. 
Spec. Char. Transversely elliptico-lanceolate, 
convex, smooth ; anterior part shortest, lon- 
gitudinally striated ; striae obscure. 
The width of this neatly formed Tellina, is above twice 
the length ; the anterior portion is somewhat attenuated., 
and has a very slight elevation upon its surface that 
extends from the beak to the edge, it is truncated ; the 
bend of the shell is inconsiderable ; the striae are hardly 
to be discovered in some specimens, they so soon wear 
off, and extend only a small distance from the anterior 
extremity. 
Siliceous casts occur now and then in the Green Sand 
of Blackdown.
