arranged under one another in oblique and more or less flexuous lines. 

 In other words, the whorls are ornamented with fine oblique or 

 flexuous lines, which are interrupted by numerous spiral sulci, thus 

 producing series of dots. Through the prominence, although slight, 

 of the two principal lirse, the whorls between them appear somewhat 

 concave, and the ridge around the base of the last whorl passes 

 just above the labrum and winds up the spire at the sutural line.

Hab. ? 



This species, the habitat of which was not hitherto known, is not 

 very fully described by Adams. The colour is subject to consider- 

 able variation. The series of granules are usually lightish brown, 

 and the interstices almost black. This simplicity of colour is de- 

 stroyed by broad, irregular, white patches radiating from the suture ; 

 and many of the granules, especially on the base, are white. Two 

 or three of the series of the interstices between them around the 

 umbilicus are white, only a few of the granules being brown. The 

 whorls are six in number and rather convex.

On comparing Andaman specimens of this species with the type 

 presented to the British Museum by the late Dr. Gray, I have not 

 the slightest doubt of their specific identity.

The colour of this beautiful species varies in some examples, but 

 appears to be constant in its distribution. The oblique arcuate 

 pink or scarlet stripes on the upper part of the body-whorl, which 

 in some specimens are black, generally terminate a little above the 

 middle. At this part the whorl is encircled by two close-set gra-
