282 RECORDS OF THE AUSTRALIAN MUSEUM. 
slighter ribs, yet with a misleading superficial resemblance. As the story 
of the Lifuan species has been entangled with that of the South Australian, 
it seems well to deal with the error as detected, though the limits of this 
paper ave thereby exceeded, and to offer the following description of the 
nameless shell. 
LIENARDIA FALSARIA 7. sp. 
(Plate xlviu., fig. 88.) 
Shell ovate-fusiform, very solid. Whorls six. Colour white, with 
ochraceous-orange as a peripheral zone, re-appearing on the spire, about 
the suture, again on the inner lip, and as a spot on the extremity of the 
snout. Sculpture:—The radial ribs are about nine to a whorl; not 
continuous from whorl to whorl; angled, and projecting at the shoulder, 
evanescent on the fasciole, but reappearing as a subsutural bead, on the 
last whorl diminishing towards the base, which they scarcely reach; both 
ribs and interspaces traversed by rather coarse, even, spiral threads. 
Aperture oblong, protected by a rather prominent arcuate varix, which is 
produced into a broad free edge, and incised by a rather deep sinus; inner 
lip with a stout tubercle at the sinus, and six horizontal ridges diminishing 
from above to below; on the opposite side are nine small pustules beneath 
the varix. 
Hab. Uoyalty Islands:—lLifu. New Caledonia. 
HYTREMA POLYDESMA Sp. 100. 
(Plate xlvii., fig. 83.) 
Shell small, spire slender and much elevated, shoulder of the whorls 
angled, base a little concave. Colour buff, chestnut on the base and both 
sides of the mouth. Whorls seven, including a three-whorled protoconch 
of the usual type. Sculpture:—On the last whorl are twenty spirals, of 
which twelve are on the base and snout, and three on the shoulder; where 
the central series enlarge and cross over the radials they look like links in 
a chain; between these major spirals run microscopic hair-lines; on the 
last whorl are twelve perpendicular consecutive radials, which undulate 
the suture, attain greatest development on the periphery, and gradually 
disappear on the base. Aperture:—Varix large, with a peaked hump; 
beneath it are six small teeth; columella unarmed; sinus broad and 
expanding. Length 4°5 mm., breadth 1:5 mm. 
This form was misidentified by myself” from Mast Head Island as 
Glyphostoma polynesiense. 
Hub. Queensland :—15 fathoms, Palm Islands (type); 5 to 10 fathoms, 
Hope Island; 5 to 8 fathoms, Murray Island; 4 to 14 fathoms, Albany 
Passage (self) ; 10 fathoms, Cape Sidmouth (Henn).
