 PLATE 56, FIGURE i. 



Pliocene marl of the Caloosahatchie River, Florida ; Dall. 



Shell small, thin, delicate, elongate inequilateral ; the beaks low, situated 

 at the anterior seventh of the valve; anterior end rounded, posterior attenu- 

 ated and almost pointed below ; posterior dorsal margin convex ; basal margin 

 straight or even slightly concave ; lunule small, broad, deeply impressed ; sculp- 

 ture of twenty-three to twenty-five small, rounded, beaded, radial ribs, sepa- 

 rated by narrower rather deep interspaces, the inner margin and much of the 

 inner face of the disk fluted by or reflecting the external sculpture ; hinge very 

 delicate, the laterals conspicuous. Length 7.0, height 4.5, diameter 4.0 mm. 



This little shell may grow larger than the specimens collected, but it is dis-
