t I have, in ray collection, five lower valves of a small species of oyster so near 

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

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

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

 identity. My specimen.? are from near Mullica Hill, New Jersey.
