It appears, by Chemnitz's figures, that this shell is about an inch 

 in diameter, nearly equally convex on both sides, longitudi- 

 nally plaited, and marked all over with transverse granulated 

 striae ; the colour is red variegated with white, and the inside 

 pearly ; Gmelin's name of nodulosus has been preoccupied by 

 Born for another species. 



DISTORTUS. 84. Shell slightly niucronated, and 

 covered all over with smooth spines.

Both Born and Favanne have considered a variety of T. Del- 

 phinus to be the T. distorttis, and Linnaeus has strongly ex- 

 pressed his doubts of keeping them separate. In the shell 

 figured by Chemnitz the length rather exceeds the breadth, 

 and the two lower whirls of the spire are much produced ; 

 each whirl has a transverse nodulous keel, and is separated 

 by a channelled suture ; it is of a rose-colour, and the base 

 nearly white, with crowded rows of concentric red granules.

CRENELLUS. 85. Shell flattish, with a spreading 

 umbilicus, and rounded striated whirls; striae 

 crenated.
