Mus. nost. From Guernsea. 



Shell about two inches long, and rather more in breadth, thick, 

 convex, yellowish-white, mostly marked with numerous red or pur- 

 plish zigzag lines, which are often disposed in interrupted longitudi- 

 nal rays, rarely of an uniform chocolate or fawn-color ; and extreme- 

 ly variable in the disposition of its marks and colors. 



The transverse striae are very numerous and rounded, not becom- 

 ing broader at the anterior side, and usually interrupted by strong- 

 transverse lines of annotination ; the anterior side is very obtuse 

 and swollen : the margin obtuse, and in full grown specimens a little 

 flexuous towards the anterior end ; beaks prominent, recurved, with 

 a purple heart-shaped areola under them ; inside white, purple, or 

 greenish-white : two of the teeth cloven. 



Lister appears to be the only author who has noticed this species. 

 We have before us a fine series, from a quarter of an inch to more 

 than two and a half in length, taken alive out of the sand at low 

 spring tides in Guernsea. It is much longer in proportion to its 

 breadth than Venus virginea ; the striae are much more numerous 

 and compact : and it is easily recognised by the remarkable tumid- 

 ity of the anterior end.
