78 PALEONTOLOGY OF NEW JERSEY. 
A few imperfect shells of this species have been observed among the 
collections from within the State. ‘They are so extremely delicate and fragile 
that they are usually broken in the sandy marl before they can be removed, 
so that only a single valve has been obtained in a condition to serve the pur- 
pose of illustration. The form is irregularly ovate, the anterior portion 
forming three-fifths of the whole length, and the end rounded; posterior 
extremity rather sharply pointed and the cardinal line abruptly and obliquely 
sloping from the beak. Surface marked with very fine lines of growth, and 
an indistinct furrow along the umbonal portion. In the interior the sinus 
is very large and deep and muscular imprints very faint. 
Formation and locality: In the gray sandy marls at Shiloh, N. J. In 
the collection of the Academy of Natural Sciences.

“Shell narrow-elliptical, compressed; posterior side pointed, extremity 
obtuse; fold submarginal, obscure; basal margin straight opposite the beak; 
lateral teeth none.” (Conrad.) 
The shells of this species are small, very fragile, and have a polished 
surface; the form is elongate, triangularly elliptical, the anterior end being 
about once and a half as long as the posterior, rounded at the end and along 
the basal line; the posterior end is more pointed and the dorsal margin rap- 
idly sloping; beaks minute; hinge very slender; teeth small; pit small 
and triangular; lateral tooth on the anterior side very slender, not very 
remote from the beaks. 
Formation and locality: The specimens are from the well-boring: at 
Atlantic City, N. J., and are in the cabinet of the Academy of Natural 
Sciences at Philadelphia.
