HeTeROCrrHARA CONCINNA sp. nov. 
(Plate xlix., fig. 107.) 
Shell small, slender, cylindro-fusiform. Colour pale buff, with a tew 
broken ferruginous lines on the back of the last whorl, on the varix, and 
in the subsutural intercostal spaces. Whorls seven, rounded, constricted 
at the suture, and subangled at the shoulder. Protoconch of two and a 
half whorls, smooth, symmetrical, conical. Sculpture :—Ribs prominent, 
narrow, as broad as their interstices, proceeding from suture to base, but 
discontinuous from whorl to whorl ; spirals are sharp widely spaced threads 
traversing both ribs and interstices, but more conspicuous in the latter, 
amounting to four on the penultimate and thirteen on the body whorl, 
the one on the shoulder being more important than the rest; besides the 
major spiral other close and minute threads over-run the fasciole area. 
Aperture:—Mouth wide, unarmed; varix narrow but elevated; sinus 
deeply excavate; canal short and wide. Length 5 mm., breadth 1:5 mm. 
Hab. Queensland :—5 to 8 fathoms, Murray Island (self). 
HETEROCITHARA BRISMATA sp. 100. 
(Plate xlix., fig. 108.) 
Shell ovate-elliptical, very solid. Colour pale cream, spotted with 
square dots of raw sienna upon the ribs between the spirals. Whorls six, 
plus the protoconch. Sculpture :—Surface rather glossy, with fine radial 
microscopic scratches; radials prominent, close-set, discontinuous ribs, 
wider spaced on the back of the last whorl, amounting to nine on the 
penultimate; the spirals are chiefly apparent as beads upon the ribs, but 
suddenly enlarge upon the snout to massive tubercles; on the last whorl 
there are nine, on the penultimate three, and on the antepenultimate two. 
Aperture:—Mouth narrow, vertical; varix prominent, the spirals that 
“ eross it are magnified into seven outstanding knuckles; sinus a deep 
U-shaped incision in the varix; canal very short; no plications or 
denticules within the outer lip or on the columella. Length 7-5 mm., 
breadth 3-5 mm. 
This species has a general resemblance to Mangelia bascauda, but 
differs by larger size, more prominent radials, and especially in the 
absence of teeth in the aperture. ;
