These shells may not be mature, but Mr. Andrews informs me 

 that he saw no larger specimens.

Hab. — Sandwich Islands. 



To Pease's brief description I add the following further details. 

 Shell minute, fusiformlj- ovate, tapering at the apex, which is pale 

 brown, the ground-colour of the rest of the shell being dark purplish 

 red, upon which the tubercles are dusky white ; whorls 11-12, apical 

 one pale, smooth, globose, three following with two spiral ridges 

 crossed by fine longitudinals forming a kind of cancellation, the 

 points of intersection becoming finely grauose upon the three next 

 volutions and more coarsely tuberculated upon the rest of the shell ; 



the tubercles are ranged in two rows on each whorl, and falling 

 fairly regularly one under another also form longitudinal series; 

 the last whorl has five rows of tubercles, the uppermost tlie largest, 

 the next with smaller tubercles, and the rest still more finely granose ; 

 aperture very small, dark-coloured within ; labrum a little thickened 

 and expanded, pale, minutely yet distinctly sinuated at the suture ; 

 anterior canal short, oblique, closed. Length 3"o, diam. r25mm. 



The suture between the whorls appears to be invisible, but by 

 following the two spiral ridges of the upper whorls down the shell 

 it is seen that the lower whorls have each two rows of tubercles.
