LIwNARDIA BERTINIANA J'apparone Canefri. 
Clathurella bertiniana Tapparone Canefri, Bull. Soc. Zool. France, 11., 1878, 
p. 247, pl. vi. figs. 7, 8. Id. Couturier, Journ. de Conch., ly., 1907, 
p. 131. 
Hab. Queensland :—Murray Island, Lizard Island, and Rocky Isle, 
off Cape Flattery (self). 
LIBNARDIA CORTICEA sp. nov. 
(Plate xlviii., fig. $9.) 
Shell small, solid, ovate-lanceolate, constricted at the sutures. Colour 
uniform ochraceous-buft. Whorls seven. Sculpture :—The radials increase 
in number but decrease in size as growth proceeds; on the penultimate 
are nine broad prominent and discontinuous ribs, which are cut into 
tubercles by the passage of spirals; on the last whorl are low and faint 
ribs which vanish on the base; the spirals on the last whorl amount to 
sixteen elevated coarse and evenly spaced cords, set at their breadth 
apart; on the penultimate the spirals are three; the persistent fasciole is 
traversed by two spiral threads, and is not interrupted by the radial 
sculpture. Aperture:—The mouth is narrow and arcuate; varix low but 
massive, ornamented by a continuation of the spiral threads; on the free 
edge of it are seven small denticules; sinus deep and rather wide; canal 
a mere notch; columella lip with a deeply seated plait, and with three or 
four superficial transverse plications. Length 5-5 mm., breadth 2-4 mm. 
Hub. Queensland :—5 to 8 fathoms, Murray Island (self). 
LIBNARDIA PALLACIOSA sp. nov. 
(Plate xlviii, fig. 90.) 
Shell small, subeylindrical, and solid. Colour apparently buff, with 
a brown band on the suture and another on the base. Adult whorls 
apparently five, angled on the shoulder and contracted on the base. 
Sculpture :—On the last whorl there are eight (including the varix) 
prominent radial ribs, and twelve evenly spaced spiral threads over-ride 
them. Aperture:—Mouth narrow; varix prominent, extending a limb 
inwards; canal and sinus wide. Length 4°5 mm., breadth 1-75 mm. 
Material for this description is imperfect, consisting of four dead and 
discoloured shells; it may be supplemented by those who obtain better 
specimens. This new species is related to L. fallaw G. and H. Nevill, but 
is shorter, stouter, and more coarsely sculptured. 
Hab. Queensland :—5 to 8 fathoms, Murray Island (type, self). 
LIENARDIA FALLAX G. and H. Nevill. 
(Plate xlviii., fig. 91.) 
Clathurella rugosa var. fallaw G. and H. Nevill, Journ. Asiatic Soe., xliv.,
