A REVISION OF THE AUSTRALIAN TURRIDA)—HEDLEY. 251 
truncated by a smooth and constricted fasciole, amounting to eleven on 
the penultimate; on the earlier part of the body-whorl these ribs are 
smaller aud closer together than previously; half a whorl behind the 
aperture is a rough varix, beyond which the ribs cease; spirals—on the 
base are about a dozen fine grooves; between the suture and the fasciole 
is a spiral ridge which tends to break up into beads opposite the ribs. 
Aperture narrow; sinus C-shaped; a thick callus knob occurs at the right 
insertion. Length 8 mm., breadth 3 mm. 
Hab. (Queensland :—5 fathoms, off the Horsey River, Gulf of Car-

MELATOMA EBURNEA sp. nov. 
(Plate xlv., fig. 43.) 
Shell solid, glossy, cylindro-fusiform. Colour uniform ivory-yellow. 
Whorls seven, including a two-whorled dome-shaped protoconch. Suture 
impressed. Sculpture:—There are no spirals; the ribs are set about 
fourteen to a whorl—they start up suddenly, immediately below the 
contracted fasciole area, are prominent, perpendicular, wide-spaced, dis- 
continuous, decreasing anteriorly, become obsolete on the last whorl, and 
vanish below the periphery. Aperture wide; no varix; lip simple; sinus 
deep, U-shaped, right insertion incrassate; throat smooth; inner lip 
overlaid with a thick polished callus; canal short and open. Length 
10 mm., breadth 4 mm. 
This is like Drellia levis Hutton, but is much smaller, with sharper 
and more numerous ribs.
