LUCINID^E. 29 



This fossil resembles L. crenulata; but it is readily distinguished from that species 

 by its less orbicular outline, its prominent and more oblique beaks, and above all, by the 

 short but very deep lunule, which extends under the beaks. The concentric sulci which 

 suggested the specific name to Mr. Conrad, are accidental, quite variable in number and 

 position, and in the larger number of individuals they are absent altogether: The short 

 and deep lunule will serve to characterise all the varieties of the species. — T. 4- H.

 Plate VI. Fig. 5. 



Description. Shell sub-orbicular, equilateral, truncately rounded anteriorly and 

 posteriorly, convex, diaphanous, concentrically and finely striated, not punctate; strise 

 numerous, indistinct, irregular; beaks prominent, but not acute; internal margin entire. 



This shell very nearly resembles L. punctulata, (Lea.) of the Meiocene of Virginia, but 

 differs from that species in being not punctulated, but concentrically, numerously and 

 finely striated ; it also differs in being of much greater size, often five times as large. 



It is very abundant in the Post-Pleiocene, but unknown in a living state. 



I have given to this shell the Indian name of Ashley River, which is Kiawah ; it was 

 upon its banks we first discovered it,
