C. with a very convex fhell, having about eighteen 

 ribs furnifhed with numerous, clofe-fet, convex fjpines ; 

 colour rudy-orange yellow. 



This fpecies differs from the aculeatum in being more 

 round, the ribs more raifed, which with the furrows are 

 more wrinkled ; the fpines are more numerous and con- 

 , tiguous, but not fo long; the fliell is ffronger, the teeth 

 larger; and in fize rarely exceeds two inches and a half 

 in diameter. Infide white, gloffy ; the ribs not fo much 

 laifed at the upper part towards the beak. Mr. Pen- 

 nant fays this fliell has Gxteen ribs: Linn^us gives it 



twenty ;
