 and from it in the inside proceed two white ridges, one trans- 

 versely towards the narrow end, and the other in a more lon- 

 gitudinal direction.

Shell about half or three-quarters of an inch long, and nearly 

 four times as broad; thin, brittle, whitish with tawny spots, 

 but often covered with a brown epidermis, and marked with 

 fine concentric striae ; it is always slightly arcuated, and the 

 hinge consists of two teeth in one valve, and one in the 

 other.

Inhabits 



Shell two inches long, and near five broad, and is thus de- 

 scribed by Mr. Wood : " flat, white, covered with a yellowish 

 epidermis, striated concentrically, and very glossy. From 

 the hinge, which has two teeth in one valve, and one in the 

 other, there runs a strong rib which spreads as it proceeds 

 across the shell, and is lost near the margin ; the upper part 

 of the muscular depression is ridged from the teeth towards 

 the end of the shell." To avoid confusion it has appeared 

 necessary, that the name of the present species should be 

 changed, as maximus had been before given by Gmelin, to 

 S. magnus, and which Mr. Wood has altered because this 

 is a still larger shell.
