 Mus. nost. Common in Torbay. 



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.
