This is a common shell. It has been taken on the beach 
as far west as LeHunte Bay and St. Francis Island, and is 
very abundant at Sceales Bay. Dredged alive at all depths 
from 6 fathoms to 19 fathoms in Gulf St. Vincent and Spen- 
cer Gulf. It has not been taken alive or dead beyond 22 
fathoms. 
The operculum has a medio-lateral internal nucleus, and 
puts the shell into the subfamily Clavatuline and out of 
Pleurotomine, and therefore out of the genus Drillia. It 
might be transferred to Clionella, but if D. harpularia is re- 
moved probably many other of our Drillias should be; and 
so T have left it with them until more of them have had 
their opercula examined.

Shell solid, high, narrow, conical, blunt at the apex, 
roundly much contracted at the base. Protoconch mamil- 
late, of two and a quarter whorls, with eighteen round axial 
ribs. Suture linear, quite inconspicuous. Spire-whorls five, 
straight, sloping, with two carine, slightly nodulated, equi- 
distant from each other and the sutures, the lower much 
the larger and rounder. Other spirals arise, so that in the 
penultimate there are two above each carina and two below 
the lower; in the body-whorl there are twelve below it; they 
are steep behind and sloping in front. Very fine sinuous 
growth strie cross them. Aperture roundly rhomboidal,
