cartilage flope in one valve frequently ftreaked tranfverfe-

 glofly white, or fle(h colour, with fometimes a brown 

 mark at one end : margin crenulated. 



This fpecies appears fuhjecl to much variety ; in fome 

 the ridges are broad, and nearly flat, others narrower, 

 and turn a little backwards, fo much refembling the Venus 

 Pap/iia oi"LiNN Mvs, tliat we are inclined to believe, with 

 Do61or PuLTENEY, that it muft be confidered as that fliell 

 in a depauperated flate. It rarely exceeds feven-eighths 

 of" an inch in lentjth ; and one inch in breadth. In com- 

 paring the foreign V. Fapfiia with this fliell, we perceive 

 m the infide the fame fhaped cicatrix, which is an effential 

 fpecific charader, not fufficiently attended to. 



Da Costa's Pj&uncuku fafciatus is evidently this 

 fhell, but his fpecimens niufl; have been worn, or he 

 would not have defcribed the margin plain. The PeU,iin- 

 culus Vetuln, of the fame author, is only a more perfect 

 varietv, with ftrong-er ridges and markings. 



It is not uncommon in fome parts of Cornioall ; fre- 

 quent about Falmouth, but more plentiful on the fouth 

 coail o( Devon, particularly on MiUon fands, 



Doftor PuLTENEY fpcaks of it as a rare fliell on the 

 Dorfei coaft. An elegant variety, radiated all over wiih 

 double and treble lines, we have found on the weflera 

 fnores,
