The figure and description of this species are not good. Indeed, 

 without the aid of a specimen identified by Brazier, I should have 

 failed to recognise the species. It seems well, therefore, to intro- 

 duce here a figure and redescription derived from a specimen 

 dredged off Port Kembla. 



Shell elongate, fusiform, thin, 

 angled at the shoulders of each whorl. 

 Colour dull white. Whorls four and 

 a half, plus a two-whorled protoconch. 

 Sculpture : wave-like longitudinal 

 ribs, amounting to thirteen on the 

 last whorl, curve across the sutural 

 shelf, are sharply angled, and project 

 at the shouldex', thence descend per- 

 pendicularly to the base, where they 

 disappear. These are over-ridden by 

 spiral cords, on the upper whorls 

 three, on the last twenty, crowded 

 below and widely spaced above. The 

 meshes of the major sculpture are 

 occupied by microscopical, dense, 

 spiral threads, ornamented by minute 

 gemmules, which give a dusty appearance to the shell. Proto- 

 conch exsert, of two whorls, smooth and glossy. Aperture wide, 

 lip simple, straight ; sinus broad and shallow, canal abbreviated. 

 Length, 7 mm. ; breadth, 3-5 mm. 



Off Cape Three Points in 41-50 fa,thoms; off the Manning River 

 in 22 fathoms; off Port Hacking in 22-38 fathoms; off" Botany 

 Bay in 50-52 fathoms; and off Port Kembla in 63-75 fathoms.
