 though more faintly, on the inner as well as outer surface.

 on the anterior side; hinge with two bifid 

 teeth in each valve.

Inhabits 



Shell about an inch and a half long, and near two inches and a 

 half broad, of a dull purple colour tinged with brown, and 

 marked with two oblique white rays from the hinge to the 

 anterior margin. Mr. Wood says, that when recent, it is 

 covered with a strong green epidermis, and that the inside in 

 young specimens is nearly white, but in full-grown shells, ex- 

 cepting the muscular depressions, it is orange-coloured. 



sanguinolentus. 25. Shell sub-oval, slightly pro- 

 duced and angulated before; hinge with two 

 teeth in each valve.

 Shell about an inch and a quarter long, and near two inches 

 broad, somewhat gibbous, slightly striated concentrically, 

 and there are also some still slighter indications of longitudi- 

 nal striae and rays ; the posterior side is rounded, and the an- 

 terior, which gapes more than the other, though neither of 

 them much, is somewhat produced and angulated at the ex- 

 tremity ; it is of a rose colour, generally becoming whiter to- 

 wards the margin. Born erroneously considered this to be 

 the Linnaean Tellina albida, and they probably have an equal 

 claim to be placed among the Tellens. Knorr, v. t. 9. f. 3.
