 Carolinas southward. Holmes and Burns ; recent from Cape Sable, Nova 

 Scotia, southward to Martinique. 



I am unable to find any distinctive characters separating the Upper Mio- 

 cene from the recent shells. The surface is normally smooth, and the varia- 

 tions of position in the scars of the left valve are remarkable. In the young 

 the lower pair of scars are usually equal and side by side ; as the shell grows 

 older their positions change, and the minor byssal scar is no longer on the 

 same level with that of the adductor. Shells which by some accident of 

 position are forced to grow in elongated form usually have the scars more 

 strung out and more nearly in a single line than the individuals which 

 maintain a normal suborbicular growth.
