A very beautiful species, and we know of no pleurotomoid 
shell which presents the same characteristics. ‘The whorls are 
six, the apex pitchy black, the remainder being white with 
bright ochreous tinting. In the younger specimens transverse 
shining white rows of large gemmee cross the whorls just above 
the sutures, and in the middle of the last whorl, below, there 
are ochre bands, in the last whorl this is followed by two 
smaller rows of gemmee, and then by a pitch black line reaching 
from the upper portion of the columellar margin, across the 
back of the shell, to the base of the outer lip. The more 
mature shell is conspicuous for the very swollen row of white 
peripheral nodules, banded below with fulvous colour. » The 
canal is short, columellar margin simple. (@vacé7ns a reveller).
