CONCHYLIA—DITHYRA. 36. 157 



Venus punctata. C/temnttz, \n. p. 42, tab. 41, tig. 430, 437. 

 Mus. nost. Devonshire, Cornwall, and Guernsea. 



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

 generally obliquely angular at the anterior end, yellowisli-white 

 or pale reddish brown, rarely plain, but mostly varigated mar- 

 bled or radiated with rosy or rich purple, sometimes spotted, oi* 

 with broad oblique rays: inside white, with generally a rosy 

 tinge; beaks near one end. 



The variety is much larger, without the angle at the an- 

 terior side, but sloping gradually to an elongated point from the 

 beaks. 



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

 in some of the young specimens, we are inclined to think 

 that it is a distinct species, and one of the numerous varieties 

 of the Venus literata.
