A REVISION OF THE AUSTRALIAN TURRIDE—HEDLEY. 279 
followed about the periphery by three prominent cords, and again on the 
base and snout by nine evenly spaced spiral threads; over-ridden by these 
spirals are about thirteen oblique riblets, which are faint on the shoulder, 
prominent on the periphery, where they form with the spirals a conspicuous 
open net-work, and vanish on the base; on the penultimate there are 
seven spirals. Aperture:—The varix is prominent; under the free limb 
of it ave five small entering plaits; the pillar is unarmed; the canal short, 
straight, and effuse. Length 4°5 mm., breadth 1-5 mm. 
Apparently this is close to Mangilia clurisculpta Melvill, which I 
have not seen, but the Australian species may be differentiated by having 
anterior spirals. 
Hab. Queensland :—4 to 14 fathoms, Albany Passage (type); 5 to 10 
fathoms, Hope Island; 15 fathoms, Palm Island; 5 fathoms, Van Diemans 
Tnlet, Gulf of Carpentaria (self); 10 fathoms, Cape Sidmouth (Henn) ; 
20 fathoms, off Endeavour Reef (McCulloch). 
HPReMA FIRMA sp. nov. 
ng) okey 
(Plate xlvu., fig. 78.) 
Shell small, very solid, and biconical. Colour ochraceous - buff, 
darkening on the spire and within the aperture to ferruginous. Whorls 
seven, including a protoconch of two and a half whorls, the last of 
which is sharply, delicately, keeled. Suture impressed and undulating. 
Sculpture :—The entire shell is encircled by comparatively coarse spiral 
threads, a pair of which on the periphery exceed the rest in size; on the 
last whorl these spirals amount to twenty-three, and on the penultimate 
to nine; the radials assume the form of peripheral tubercles, set at ten to 
a whorl; on the base each rib splits into two small riblets. Aperture :— 
The varix is large and prominent, having four teeth on the oral margin ; 
sinus broad and pouting; canal short and open; columella lip crossed by 
four plications. Length 6 mm., breadth 5 mm. 
Hab. Queensland :—5 to 10 fathoms, Hope Island (type, self).
