I have seen a very young specimen of this species from the Ripley Group in New 

 Jersey. It is in the cabinet of Mr. Lea, and was found in a bed with the same litho- 

 logical 'characters as the Ripley in the South, and associated with Leda protexla, 

 Gabb, Legumen ellipticus, Con., Leda longifrons, Con., Pinna laqueata, Con., and other 

 species, all of which are characteristic of that group. I believe this to be the first 

 time that this group has been recognized north of Tennessee, and we now have the 

 key to the synchronism of the cretaceous formations east of the Mississippi.
