As Voluta brazieri Cox, 1873
Shell oblong-ovate, thin ; spire very slightly raised, acute; whorls smooth, striated longitudinally with lines of growth, and very finely closely striated throughout transversely with fine sculptured lines, apex granular; last whorl large and ventricose, shouldered towards the apex, and moderately contracted at the base; columella three-plaited, the plaits thin, close-set, prominent, and short; aperture ascending as high as the shoulder of the last whorl, narrow above, much wider below, owing to the receding columella ; outer lip scarcely thickened, indistinctly banded about the centre with dark chestnut, ornamented with irregular buff-coloured markings.
Length 1,10; width 0,55 of an inch.
Hab. Wooli Wooli, Clarence River, east coast of New South Wales.

Type locality: Wooli, Clarence River, New South Wales, Australia. Range: The central northeast coast of New South Wales and deep waters off Lord Howe Island.
Habitat: Its actual habitat is unknown. Dead specimens are dredged occasionally at 50 m depth.

Description: Shell is small and light, subconical, measuring 20-35 mm, with a very low spire virtually covered by the expanded body whorl, which almost represents the total length of the shell. Violet protoconch of two whorls, rounded and turbinate. Teleoconch is of 5 whorls. The first three whorls sculptured by 11-13 thin axial ribs. Body whorl is smooth and glossy. Aperture is pinched posteriorly and flared anteriorly. Outer lip is slightly thickened. There are three well-defined columellar plaits, followed adapically by weak lirae. Yellow background amply covered by three chocolate spiral bands on fresh specimens, concealing 20-25 fine spiral lines. Specimens from deep water off Lord Howe Island bear a lighter colour close to that of L. deliciosa. Animal: Not available for study.

Comparison: Its swollen body whorl precludes any confusion. Remarks: Due to its probable rather deep habitat, this elusive species remains poorly known, and very few specimens have been collected alive. Regarding the inflated shape and the glossy smooth surface of its body whorl, Iredale (1937) gave this species the full subgenus rank Lyrenata. However, apart from these two characteristics, the protoconch, first whorls and pattern are closely related to that of the cassidula/deliciosa-complex and confirm a very close relationship.

TYPE: Holotype of Lyreneta laseroni Iredale, 1937, the Australian Museum, Sydney, No. C.62057; holotype of Voluta (Callipara) brazieri Cox, 1873 (= Lyreneta laseroni Iredale, 1937), British Museum (Natural History), London, No. 1904.5.10.1000. TYPE LOCALITY: Point Halliday near Cape Hawke, central New South Wales, Australia. RANGE: From Cape Hawke, central New South Wales, to Mullaway, northern New South Wales, Australia. HABITAT: Dredged in 20 to 30 fathome. DIMENSIONS: Adult specimens are 22 to 28 mm in length. SHELL DESCRIPTION: Shell is small and subconiform, with a very low spire, blunt at the apex. Protoconch is turbinate, of two and a quarter smooth whorls. Teleoconch has about four low whorls; the first two are axially ribbed. Adult body whorl almost equals the length of the shell. Suture is slightly impressed. Aperture is pinched posteriorly and flares an- teriorly. Outer lip is inflexed, smooth inside, and thickened outside by an obtuse ridge; interior is pale violet. Siphonal notch is wide and shallow; fasciole indistinct. Columella is recurved, with three anterior plaits (the second being strong. est) followed by about three recessed lirae that terminate below the midpoint. Base color is yellowish-flesh, almost completely covered in dark chestnut or chocolate. Two light- colored bands appear on the adult body whorl. Base color shows through as scattered spots on the spire. Occasional interrupted spiral lines appear at the outer edge of the lip. ANIMAL AND RADULA: Not available for study. REMARKS: This rather rare species was named for Mr. C. Laseron, who provided some of the specimens used by Iredale in his 1937 description. A live-collected specimen in the collection of Mr. Gordon Jarrett exhibits the glassy polish of a cowrie.
