Academy of Natural Sciences for some time. Its general appearance 

 externally is very much that of a young CrassateUcty but the interior shows 

 distinctly that it is not. 



Formation and locality, — In the micaceous clays below the Lower Marls 

 at Haddonfield, New Jersey. Collection of the Academy of Natural Sciences^ 

 Philadelphia.

Mr. Conrad's description of this species is as follows: ^^ Minute, trian- 

 gular, compressed, equilateral, summit acute ; posterior extremity angular ; 

 disk with numerous very regular, close concentric lines Locality : Had- 

 donfield, N. J." 



I have sought, in the collection of the Academy of Natural Sciences of 

 Philadel|)hia, among the specimens from this locality, for Mr. Conrad's type 

 of this species, but was not able to find it. Being so small, it has prob- 

 ably been lost. No other specimen corresponding to the figure and descrip- 

 tion has been observed so far as I am aware, but it will probably be found 

 and recognized if at any time the locality at Haddonfield should be opened 

 and carefully examined. At present the pits are not in a condition to fur- 

 nish any material whatever. I have copied Mr. Conrad's figure as care- 

 fully as possible, further enlarged, so that an idea of the character of the- 

 shell can be obtained from it. The original specimen was only about one- 

 sixteenth of an inch wide.

I have not been able to find any specimen from the Cretaceous strata 

 of New Jersey corresponding exactly to this species, nor have I been able 

 to find Mr. Conrad's type specimen. I have, therefore, copied his figure as>
