canal short and open, slightly bent to the left. Outer lp 
thin, simple, crenulated outside by the spirals. Colour dull- 
creamy-white, with irregular faint-brown narrow axial 
flames, with a tendency to follow the curve of growth lines. 
The larger carinz are more or less regularly articulated with 
brown. 
Dim.—Length, 8 mm. ; body-whorl, 46 mm. ; width, 33 
mm. 
Locality.—Type in 40 fathoms off Beachport, with 5 
others. 
The protoconch is not the usual one of Drillia; it re- 
sembles closely that of /usus lincolnensis, Crosse and Fischer, 
but the growth lines indicate a shallow, round sinus just be- 
low the suture, between the two carinez, which is not found 
in Fusus. The type is immature, and the others are imperfect. 
A perfect adult may eventually determine the genus.

Sowerby says in a note to his definition: —“‘There are no 
longitudinal ribs,” but in the shell returned to me as the 
type there are very faint oblique axial plications, and in sonie 
‘specimens since collected these may be properly styled axial 
riblets. The shell may be of a dark-brown colour, with bands 
and flames of darker tint, or any lighter shade of brown to 
white, the tip being generally most coloured. 
Mr. Hedley, on seeing my specimens, wrote: —‘‘What I 
named as a variety of J). haswelli, Medley, from Cape Pillar 
(Records of the Austr. Mus., vol. vii., No. 2, 1908, p. 112), 
is evidently your D. dulcis, Sow. Typical D. haswelli is dis-
