HIEMILIENARDIA HERSILIA sp. nov. 
(Plate xlix., fig. 104.) 
Shell small, ovate-pointed, contracted at the sutures and at the base. 
Colour dull-white, an opaque white band at the back of the last whorl. 
Whorls seven, of which three are apical. _ Sculpture:—The radials are 
discontinuous, vertical, moderately prominent ribs, which diminish at the 
sutures and vanish on the base, and are set at ten to a whorl; the spirals 
are prominent cords which over-ride the ribs, four on the penultimate and 
twelve on the last whorl; of these the anterior five run across the snout, 
and are beaded. Aperture:—Month sinuate; varix composed of a double 
rib, the free limb traversed by eight spirals and the edge armed by four 
tubercles, becoming larger as they ascend, the lowest double; columella 
with two deep-seated plications; sinus and canal broad and shallow. 
Length 3:5 mm., breadth 1:7 mm. 
Hab. Queensland:—5 to 8 fathoms, Murray Island (type, self) ; 
Palm Island (self). 
HEMILIENARDIA HOMOCHROA sp. 70U. 
(Plate xlix., fig. 105.) 
Shell small, solid, elongate-ovate. Colour entire deep rose pink, 
except an opaque white zone which is at first one spiral broad and at last 
three rows broad. Whorls eight, first three and a half apical, rapidly 
increasing. Sculpture:—The radials are twelve prominent round-backed 
ribs, ceasing on the base, discontinuous from whorl to whorl, and broader 
than their interstices; the spirals amount to sixteen on the last whorl, 
and to four on the penultimate; they are stout close set cords which 
traverse both ribs and interstices and continue on the base; there they 
carry large beads in continuation of the axes of the ribs; the whole 
surface is also microscopically shagreened. Aperture:—The mouth is 
vertical, contracted by the limb of the varix, the free edge of which is 
armed with five prominent tubercles; columella excavate and twisted ; 
sinus deep and narrow. length 5 mm., breadth 2°5 mm. 
This is an Australian representative of H. malleti Recluz from the 
tropical Pacific. It is easily and definitely distinguished by having the 
protoconch coloured like the rest of the shell instead of being a brillant 
white like that of malleti. 
An example of this was found by Mr. J. Brazier in a rock pool, 
between tide marks, at Little Coogee, near Sydney, 19th July, 1895. 
Though immature it is quite sharp and fresh, and had evidently lived 
where it was found. Still I should consider that this species is not an 
ordinary resident of so southern a latitude, but that this individual was a 
waif swept down by the Notonectian current, perhaps in a larval state. 
Hub. Queensland :—Two Isles, off Cape Flattery (type, self); Green 
Island (self). N.S.Wales:—Little Coogee (Brazier).
