The shell thus labelled in the “Chevert” collection does not agree 
with Reeve’s figure. 
Hab. Queensland :—5 fathoms, Cape York (Brazier). 
HUCITHARA ARBENIVAGA sp. ov. 
(Plate xlvi., figs. 56, 57.) 
Shell solid, biconical, slightly constricted around the upper part of 
each whorl. Whorls nine. Colour lavender-gray, with a broad peripheral 
band of buff descending the spire, and on the last whorl underlined by a 
single or double chocolate line; lp buff; interior ochraceous brown. 
Protoconch of two small helicoid whorls. Sculpture :-—-The first whorl is 
keeled, and developes small radial ribs; on subsequent whorls the ribs 
amount to about ten, not continuous from one whorl to the next, bent, 
and thickened on the shoulder, thence quickly tapering to the suture, 
continuing in the opposite direction to the base of the last whorl; the 
whole shell is over-run by microscopic spival threads, alternately larger 
and smaller. Aperture:—The mouth is narrow, oblong, protected by a 
stout vyarix which ascends the previous whorl, and in which is excavated 
a shallow semicircular sinus; the lip has a very narrow free margin, 
within which are about eight small inconspicuous teeth; the columella is 
overlaid by a thick callus sheet with a definite margin, across it extend 
ten plications; canal a mere notch. Length 12 mm., breadth 4-5 mm. 
This is related to the New Caledonian H. questieri, but differs in 
colour, the general tone being slate, not brown; in being more slender, 
and having the ribs further apart. There is a general resemblance to 
EH. reticuluta, but H. arenivaga is smaller, with fewer and more widely 
spaced ribs. Both extremities of arenivagu taper more, and the body 
whorl is proportionately smaller. 
Hab. Queensland :—Cape Flattery (type), several specimens crawling 
in pools and over wet sand north of the headland; bar of Annam River 
(self) ; Cape York (Brazier).
