Behind these bands is one narrower and less distinct, and another 
at and behind the angle ; one between the broad bands, and two 
in front of the lower one. Between all the bands are narrow 
indistinct whitish areas. The inner edge of the lip is white, 
with Jess distinct and narrower coloured areas corresponding with 
the bands outside. The throat is translucent, and reveals faintly 
the external dots and bands. 
Habitat.—Two recent and two broken shells, 20 fathoms 
Newland Head ; one immature dead and one broken, 22 fathoms 
Backstairs Passage ( Verco ). 
This new species cannot be confounded with any other form. 
The distant ribs and dotted ornament distinguish it at once. 
iryon Says, i his Man. of Conch. Vol. V., p. 97, ‘ Yake 
Strombus, Harpa appears to be a completed genus, no new forms 
rewarding the industry of modern investigators and explorers.” 
The discovery of a new species is, therefore, of peculiar interest. 
And this is increased by the fact that the two other Australian 
forms, H. ventricosa, Lam., and H. minor, Lam., are inhabitants 
of the warmer regions of the North and North-West parts of 
the continent. 
Tritonidea (Cantharulus, Meek, 1876) fusiformis, spec. nov. 
Piova.y boss bla, 3 var.e2s. 2a: 
Shell ovately fusiform, solid, whorls seven, including the 
nucleus. Nucleus conspicuous, of two turns, smooth, convex ; 
suture deep, apex slightly exserted (in specimens as usually found 
on the beach it is inconspicuous, and nearly flat.) Spire-whorls 
four, convex, sutures regular distinct, impressed ; longitudinal 
costz regular round, width rather greater than the intervals or 
the height. Thirteen in the penultimate whorl, crossed by spiral 
liree, rounded, valid, not quite so wide as the interstices, nine 
primary in the penultimate, with two or three secondary thread- 
lets in the wider spaces; very numerous fine longitudinal sub- 
lenticular incised stria. Body-whorl uniformly convex, con- 
tracted anteriorly ; 11 to 12 longitudina! costz, most marked 
posteriorly, becoming less valid in front of the periphery. About 
30 spiral lire, fairly regular, with an occasional interstitial 
threadlet crossed by minute incremental incised striz. Aperture 
elongately oval, somewhat narrowed anteriorly. Outer lip 
uniformly convex, margin sharp, minutely crenulated throughout, 
outside varicosely thickened from suture to notch by a rounded 
pad with a corresponding furrow inside of varying depth in 
different specimens ; internally otherwise smooth, save for an 
obsolete blunt tooth-like process close to the suture ; in some 
individuals there are seven or eight narrow plicate denticles 
nearly equidistant. Columella concavely arcuate above, straight
