B. testd conico-acuta,subturritc\,albido-cornea. vel cinereo-CEerulescente ; 

 anfractibus convexis, striis impressis teriuibus distantibus cinctis superne 

 bicingulatis : cingulis plicato-granulosis ; fauce fulvo-fuscescente. 



Shell elongated, conical, slightly turreted, of a bluish or 

 ashy white color ; spire very pointed at its summit, composed 

 of nine or ten slightly convex whirls, united by a shallow 

 suture, and furnished at their upper part with very close small 

 folds or granulations ; these folds form a girdle, and 'crown the 

 whirls, which are again ornamented throughout their whole 

 length with transverse thin ridges, more strongly prominent 

 towards the base ; there appear, besides, upon the lowest 

 whirl, oblique striae of growth pretty apparent, and presenting 

 sometimes the appearance of varices ; one or two striae separate 

 also the folds from the upper marginal edge. The aperture 

 is oblong, slightly narrowed, dilated at its base, where it is 

 terminated by a very deep and slightly oblique emargination. 

 The interior of the aperture is of a brown fawn color; right 

 lip white, thin and sharp ; columella white and rounded. 



Length 2 inches 2 lines. Width 8 lines. 

 Inhabits the Indian Ocean. 



Lamarck has withdrawn this species from the genus BUCCI- 

 NUM of Linnaeus, in order to unite it to the genus TEREBRA of 

 Bruguiere. This learned naturalist, in determining this shell, 

 regarded merely the length of the spire ; but it has in many 

 respects so much alliance to the BUCCTNA, that many recent 

 authors think it should be restored to the genus, where Linnaeus 

 originally placed it. The coloring of this shell is quite varia- 

 ble. Some specimens are of a livid yellow, others of a bluish 

 violet. Lamarck has also established, as a species, under the \
