126 TALuEONTOLOGY OF JSIEW JERSEY. 



Academy of Natural Sciences for some time. Its general appearance 

 externally is very much that of a young Crassatella, 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 

 Philadelphia, 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 al)le 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-
