 Mus. nost. Devonshire, Cornwall, and Guernsea. 



Shell an inch and a half long, and nearly two in breadth, gener-

 reddish brown, rarely plain, but mostly variegated marbled or radia-

 oblique rays : inside white, with generally a rosy tinge ; beaks near 

 one end. 



The variety is much larger, without the angle at the anterior side, 

 but sloping gradually to an elongated point from the beaks. 



From the total want of the angle, which we have also observed in

 distinct species, and one of the numerous varieties of the Venus 

 literata. 



Venus testa ovato-rhombed, medio tumido striis transversis crebris Ion- nitens. 



gitudinalibusque ohsoletis, dente medio jisso. 

 Shell rhombic-oval, tumid in the middle, with crowded transverse 



striae and obscure longitudinal ones, and the middle tooth cloven.
