Cardiomya sp.! 
A single left valve, Station 321, off Charleston, S. C., in 233 fathoms. 
This specimen is badly broken, but shows an oblique, inflated form, with a 
very short, ill-defined, upturned rostrum, and a nearly smooth, slightly lustrous 
surface. On the posterior end there are several rather inconspicuous angular 
ribs. Two principal ones diverge from the beak to the margin. The upper one 
defines the rostrum, and has above it three fine, little raised radiating lines, 
which commence about half-way down from the beak and reach to the end of 
the rostrum. The second or lower rib has two or three shorter ones above 
and below it, which commence, as the lines on the rostrum, half-way down 
from the beak, and extend to the margin, which they make a little fluted. 
These ribs appear as shallow grooves on the interior of the valve. The rest of 
the surface is crossed only ad indistinct, unequal lines of growth. 
Length, 9 mm; height, 7 mm.
