B. testa parva, ovato-globosa, lutea, apice acuta, longitudinaliter plicata, 

 transversim echinata; apertura alba ; labro dextro crasso, intus striato. 



Shell small, ovate, subglobular, spined, spire conical and 

 pointed, composed of six or seven whirls ; the lowest much 

 larger than all the others ; presenting on its exterior longitu- 

 dinal folds, upon which are regularly disposed pointed, conical 

 tubercles, which are of the same color as the rest of the shell. 

 The first row of these spines is situated immediately beneath 

 the suture ; the last one obliquely intersects the base of the 

 shell. Transverse striae, pretty fine and numerous, are observ- 

 ed between each of the rows of the spines. Aperture white, 

 semilunar. Right lip thick, furnished internally with fine 

 striae ; columella nearly straight, covered by the left lip which 

 forms a callosity. The color is uniform, of a white fawn, 

 sometimes pale orange. 



Length 7 lines. Width 4 lines. 



Inhabits Cartaret Harbor at New Ireland. 



This little shell, which is quite rare, in many respects resem- 

 bles the BUCCINUM subspinosum ; only it is a little more elon- 

 gated, and the spires are more numerous. These two species 

 have the aspect of some RICINUL^E.
