This rcmaikably variable species is but poorly figured in Bunker's 

 work. The ilhistration above cited represents the spire much more 

 obtuse at the apex tlian is usual. The operculum is purpuroid. 

 The following measurements will show how variable is the size of 

 different specimens : —

The operculum of the single specimen of this species is of a bright 

 vinous red colour, of an elongate subtrigonal form, the angles being 

 rounded and the margins simple. The shell itself differs from the 

 ordinary form of the species in having a less elongated spire, and 

 the body-whorl less inflated and encircled with only eight red lines 

 instead of nine.

The costff! in the Japanese specimen are fewer than in the 

 originally described examples. In the latter the penultimate whorl 

 has about 32 upon it, whilst the same volution in the former has 

 but 22 to 24; in one specimen, however, there is the normal number. 

 The largest example is 28 millims. long and 12 wide. The operculum 

 (fig. 45a) is rather elongate, brown, serrated along the outer margin 

 and also on the inner edge for a short distance from the nucleus.
