Inhabits the coasts of Malabar, and the island of Vanikoro. 

 It was brought from the latter place by Quoy and Gaimard. 



Lately, and almost at the same time, this shell has been de- 

 scribed by three authors, under three different names : the first, 

 Wood, in his catalogue, has called it BUCCINUM textum, pi. 28, 

 fig. 113. Deshayes, describing it in the Voyage aux Indes 

 Orientates of Bellanger, gave it the name of BUCCINUM Blain- 

 villii ; and, lastly, Quoy and Gaimard, at the same time, figured 

 it in their second Voyage autour du monde, pi. 32, fig. 30-31,

 summit, and crowning the whirls. These ribs rarely extend

 besides, upon the exterior surface, numerous transverse striae, 

 very fine and very close, which, at the base of the lowest 

 whirl, are changed to wrinkles more or less numerous. The 

 aperture is ovate, its interior of an ashy violet, the oblique
