f I have, in my collection, five lower valves of a small species of oyster so near 

 this species, that I can find no difference of sufficient value to found even a va- 

 riety. I have never seen the upper valve, but, should it agree with M. Leyme- 

 rie's figures as well as the lower ones, it will remove all doubt of their specific 

 identity. My specimens are from near Mullica Hill, New Jersey.
