Sir Joseph Verco observed # that the operculum of Drillia harpularia 
requires the transference of that species from Twrritine to Olavatuline. 
Agreeable to the suggestions of Weinkauff and Verco, and pending further 
information on the opercular and other characters, the following Australian 
species are therefore tentatively grouped in a Clavatuline genus. Drillia 
buchananit Hutton, from New Zealand, may be included here. 
M. bednalli, eburnea and woodsi are distinguished from the rest by a 
particularly glossy surface, and absence of the usual spirals. To these 
Drillia lenis Hutton, from south New Zealand, is related. To contain 
these I propose a new sub-genus—Splendrillia, with M. woods: for type.

MELATOMA DAMPIERIA sp. i0v. 
(Plate xly., fig. 41.) 
Shell slender lanceolate, long, and solid. Colour uniform liyid-brown 
to russet-vinaceous. Whorls eleven, including a mucronate protoconch of 
two whorls. Sculpture:—Surface in general polished; the fasciole a 
broad and rather deeply sunken furrow, crossed by fine concentric growth 
lines, and traversed by a median sulcus; above it runs a prominent sub- 
sutural ridge; between the fasciole and the anterior end are twenty-two 
spiral grooves, which grow wider and deeper towards the base, and 
smaller and more crowded on the snout; the radial ribs are seventeen to 
a whorl, prominent on the shoulder, and gradually vanishing towards 
the base, higher on the penultimate, and decreasing towards the aperture. 
Aperture pyriform; lip simple; sinus U-shaped, rather large; a boss of 
callus near the insertion of the lip and a separate sheet of callus on the 
lower columella; canal short and wide. Length 30 mm., breadth 9 mm. 
This species resembles M. harpularia, but is much larger, purplish in 
colour, with weaker radials but stronger spiral sculpture. 
Hab. Western Australia :—Shark Bay (type in Macleay Museum). 
MBLATOMA DUPLARIS sp. nov. 
(Plate xlv., fig. 42.) 
Shell small, solid, lanceolate. Colour dull cream, with a faint dorsal 
zone of brown. Whorls eight, including a two-whorled protoconch. 
Seulpture:—The radials are smooth round-backed perpendicular ribs,
