PI. XIX, fig. 70. 



B. testa ovato-conica, griseo-cinerea, acuta, longitudinaliter plicata, 

 transversim striata ; ultimo anfractu convexiore ; aperturu ovata, viola- 

 cea ; labro dextro intus striato. 



Shell ovate, conical, of an ash-gray color ; spire pointed, 

 composed of six or seven whirls, the lowest of which com- 

 poses alone nearly half of the shell ; this is swollen, and 

 slightly compressed above. The other whirls are somewhat 

 convex, except the last but one ; their surface is ornamented 

 with eleven or twelve distant, prominent, rounded, longitudinal 

 folds, intersected transversely by fine compact striae. Aper- 

 ture ovate, slightly oblique, of a violet gray ; right lip furnished 

 interiorly with numerous striae which are continued even to 

 the depth of the cavity. Columella smooth and whitish, with 

 a pretty prominent fold at the base. 



Length 1 inch. Width 6 lines. 

 Inhabits the Isle of New Ireland. 



We refer to this species, a shell described and figured by 

 Quoy and Gaimard under the name of PURPTTRA nassoides. 

 Voyage de T Astrolabe, page 564, pi. 38, fig. 10-10. 



The specimen which was made use of by those naturalists, 

 appears to us to be the same shell, only smaller, and in a less 

 perfect state of preservation ; for it presents precisely the same 

 characters as that of which we have just given a description.
