Shell a quarter of an inch long, and an inch broad, of an oblong 

 linear shape, rounded at the ends, and not diagonally divided, 

 but of an uniform greenish brown color. 



The teeth of this shell are remarkable. In one valve are two 

 teeth, one of which is erect, and the other inclining towards the 

 cartilage. In the other valve are three teeth, close together at 

 their base, the middle one deeply divided with the segments 

 divaricate and pointing in opposite directions. 



The terminal ones can hardly be considered as lateral processes, 

 having no attachment to the margin, but originating from a 

 common base. The points of all are obtuse and very slightly 

 cloven.
