Glyphostomu tricolor Hedley, Rec. Austr, Mus., iv., 1901, p. 122, pl. xvi., 
fig. 3. 
This species is related to a shell usually, though perhaps incorrectly, 
known as a large form of mighelsi. From that L. nigrocincta is distinguished 
not only by the yellow band but also by greater breadth and solidity, more 
prominent sculpture, and fewer stouter spirals. The Queensland form is 
shorter (5°6 mm.), comparatively narrower, and with two spirals less than 
the typical form from New Caledonia. 
Hub. Queensland :—Palm Islands, type of tricolor (Brazier) ; Cape 
York; Lizard Island; Hagle Island; Two Isles; and Rocky Isle (self). 
LIENARDIA PERISCELINA sp. nov. 
(Plate xlix., fig. 95.) 
Olathurella rava Brazier, Proc. Linn. Soc. N.S.W., i., 1876, p. 17 (not 
Clavatula rava Hinds, Zool. “Sulphur,” 1., 1844, p.17, pl.v., fig. 8). 
Shell’ solid, narrowly elevate. Colour buff, with a brown line along 
the suture and another on the base. Whorls eight, inclusive of the 
protoconch. Sculpture:—The surface is microscopically grained ; the radial 
ribs, which are prominent, perpendicular, and subcontinuous, commence 
below the suture and gradually vanish on the base; on the last whorl 
there are nine of these, exclusive of the varix. The penultimate has six 
and the last whorl seventeen spiral threads; of these the posterior three 
are small aud close together, the next six are strong and evenly spaced, 
a wider space than usual then occurs in the hollow of the base, followed 
by three noduled spirals and concluded by five small spirals crowded on 
the anterior extremity. Aperture narrow, about a third of total length ; 
yarix moderately extended, edge thickened and bearing five or six denticules 
ou the inner side; canal a little bent, short, and effuse; columella with 
from three to six external entering plaits. Length 8 mm., breadth 3-5 mm. 
This shell has some likeness to the figure of Plewrotoma compta Reeve, 
but is of more slender contour with bolder spirals. 
Hab. Queensland :—12 fathoms, Torres Straits (type, Brazier); 5 
to 8 fathoms, Murray Island; 4 to 14 fathoms, Albany Passage (self). 
LIENARDIA PUNCTILLA sp. 100. 
(Plate xlix., fig. 99.) 
Shell small, solid, lanceolate. Colour dull white, with an orange line 
in each of the principal interstices. Whorls seven, of which two compose 
the protoconch. The initial whorl is turbinate, smooth, and wound so 
obliquely as to overhang the next on one side; the second is also smooth, 
with a peripheral thread keel. Sculpture :—There are six perpendicular
