Shell oblong elevated, rather thin. Whorls four (excluding the protoconch) wound obliquely, contracted at the suture. Protoconch dome-shaped, smooth, glossy, of two whorls, the first minute, the second large. Colour uniform pale yellow. Sculpture: the earlier whorls have each three elevated spiral keels, the upper smaller; below the periphery of the last whorl is another large keel, followed by a series of successively diminishing close spirals. The spiral sculpture is overridden by fine widely spaced radial threads. Aperture fortified by an expanded varix of the Lotorium pattern. Throat smooth. Canal short, slightly recurved. Length, 6,25 mm.; breadth, 3 mm.
One (the type) from 63-75 fathoms off Port Kembla; a young shell 11-15 fathoms off the Crookhaven River. Also dredged in 100 fathoms by Mr.G. H. Halligan and myself sixteen miles east of Wollongong.
