Hab. San Christoval, Solomon Islands. 



The spiral lirse whicli encircle the body-whorl around the middle, 

 are stouter than the rest ; and those beneath are very fine indeed. 

 As these lirations are rather close together and interruptedly of 

 a dark olive-colour, the shell displays more of this tint than of 

 the yellowish ground-colour.

Perhaps the nearest ally of this species is CI. atropurpurea of 

 Grould. From that species, however, it may easily be distinguished 

 by its difference of colour, channelled suture, more rounded spire 

 and the peculiarity of the umbilicus. The main colour of C. ha- 

 thyrliapJie is a very dark olive-green, the apex being bright green ; 

 the granules of the infrasutural series, which are considerably lar- 

 ger than the rest, are dark brown at intervals, two or three together 

 being of this colour, and those between them of tlie same hue as 

 the she'l. The granules on the base are subaltcrnately reddish 

 brown and greenish.
