Inhabits the shores of the Nicobar Islands. Chemnitz. 



Shell an inch and a quarter long, and four inches broad ; thin, 

 pellucid, white when stripped of its yellowish epidermis, 

 and striated concentrically. Chemnitz says, that a rib pro- 

 ceeds in the inside from the hinge, though from the terms 

 which he uses in describing it, it is difficult to ascertain its 

 direction, and in this, as well as all other respects, the species 

 appears to be very nearly allied to the foregoing. 



minimus. 12. Shell linear-oval, straight; hinge 

 lateral, with two teeth, of which one is bifid, 

 and furnished with a longitudinal rib.

Inhabits the coasts of Tranquebar. Chemnitz. 



Shell half an inch long, and one inch and a quarter broad, and 

 in form and colour resembles S. magnus ; Chemnitz says, 

 there is in the inside a rib running longitudinally from the 

 hinge to the margin, and I much doubt whether it is more 

 than a young shell of either S. Gigas, or S. magnus. 



guineensis. 13. Shell oblong-oval, ventricose, sub- 

 pellucid, and the inside furnished with a lon- 

 gitudinal rib.

Shell rather more than an inch long, and near three inches 

 broad ; white, with the margin by the hinge thickened, and 

 the inside furnished with a strong longitudinal rib. 



inflexus. 14. Shell ovate-oblong, with the margin 

 somewhat inflected ; hinge with two teeth in 

 one valve, and a prominent longitudinal rib.
