Well distinguished by the two yellow bands on a white 

 ground; but as these bands color the cuticle only, and not 

 the shell-substance beneath, they are liable to be rubbed off, 

 though at least traces of them are visible on all the speci- 

 mens I have seen. 



7. P. KERCADONIS (Grateloup). PL 16, fig. 77; pi. 8, fig. 41. 

 ' ' Shell oblong-conic, thin, substriate ; buff-roseate, orna- 

 mented with oblique reddish- violaceous nammules; whorls a 

 little convex, granulose at the suture. Aperture obovate, 

 the lip very acute. 



" The shell is conoid, elongate, thin, fragile, finely striate; 

 its surface is yellowish, a little rosy. It is flamed with ob- 

 liquely longitudinal unequal fringed spots of a brown color 

 with a violet tinge. The right margin is very thin and sharp. 

 The 7 whorls of the spire are noticeably convex, the last two 

 prettily granulate at the summit, along the suture. Length 

 45 to 50, diam. 25 to 28 mm." (Grat.).
