The fulvou.s bands are not alway.s present ; but this species may 

 be distinguished from the Donax complanata by its color, and the 

 want of the pale band, which in that shell is always more or less 

 distinctly visible. 



Donax testa cuneatd Icevi vinaced immaculatd, dente laterali in utrdque 



valvd. 

 Shell wedge-shaped, smooth, of an uniform pale claret color, with a 

 single lateral tooth in both valves.

Shell hardly the eighth of an inch in diameter, wedge-shaped

 and semitransparent, of a pale claret color, which as in the Kellia 

 rubra often changes nearly to white, except about the hinge ; in.side 

 glossy, paler than the outside, with the margin plain : beaks prom- 

 inent, very near the truncated end ; the lateral teeth one in each 

 valve on each side, near the primary ones.
