56 PALEONTOLOGY OF NEW JERSEY. 
being marked with narrow, distant, impressed lines, while on this one the 
ribs.are prominent and rounded, with sharp narrow sulci between. The 
feature, mentioned by Mr. Conrad, of the ribs suddenly becoming obsolete 
toward the posterior margin, is only partially correct, as but few of the 
specimens show it distinctly enough to be a pronounced feature. 
Locality: My. Conrad gives near Mullica Hill, N. J., as the only locality, 
and I have seen no specimens which I could identify with it from any other 
place. Those used are all from the cabinet of the Academy of Natural 
Sciences, Philadelphia, and are presumed to be the originals of Conrad’s 
description.

“Suborbicular, with about twenty-five convex ribs, and wrinkled 
across; inner margin crenate. 
“Beaks nearly central, a little prominent, curved backward; ribs gran- 
ulated on the umbones, and transversely wrinkled near the base, convex; 
apices somewhat prominent beyond the general curve of the shell; txner 
margin and edge crenate; cardinal teeth two. 
“Length from the apex to the base four-fifths of an inch, breadth 
nearly the same. 
“Rather proportionally longer than the decussate and more oblique.”

The specimens obtained from New Jersey are all below the adult size, 
the largest having a height of less than five-eighths of an inch. They are 
all single valve and nearly all show evidences of much trituration on the 
beach before imbedding, some to the extent of having the deep crenulations
