Hab. Bougainville Island, Solomon group (Brazier). 
A very pretty species, distinguishable from the black variety of 
H. meta, Pfr., by its invariably smaller size, by the presence of the 
straw-coloured band below the keel instead of next the suture, and by 
the last whorl being more distinctly keeled and less convex beneath.
