threads may arise; a funicular rib on the anterior end of the shell encloses 
a small false umbilicus; the fasciole is broad, and is appressed to the 
suture; it is smooth save for crescentic growth lines. Aperture :—The 
sinus is wide and V-shaped; the outer lip is arched forwards, and the 
free sharp edge is bent inwards a little towards the aperture; opposite 
the base of the canal is a stromboid inflection; canal short, wide, and 
sharply recurved; columella overspread with a thick callus rising in a low 
tubercle opposite the sinus. Length 46 mm., breadth 15 mm. 
This is a member of the group of Drillia flavidula. In size and 
contour it resembles the Japanese Drillia jeffreysi Smith,* but the Queens- 
land shell is narrower, the nodular ribs not so prominent, and the spirals 
are finer and closer.

Shell rather thin, elongate-fusiform, turreted. Whorls ten. Sutures 
channeled. Colour pale buff, with rust dots between the peripheral 
nodules, and irregular rust streaks and splashes elsewhere. Sculpture :— 
On the summit of each whorl isa collar of two strong spirals; besides, the 
whole surface is over-1un with fine, close, flat-topped spiral threads, 
amounting to about fifty-five on the last whorl; along the shoulder runs 
a row of upright tubercles, twice as high as broad, and more than their 
own breadth apart—twenty-two on the penultimate whorl, most distinct 
on the earlier whorls, and gradually fading till they almost disappear on
