Shell small, solid, acicular, contracted at the base, and a little excavate below the suture. Whorls eight, three and a half of which form the protoconch, of which the apex is produced and the third whorl is keeled. Colour faded in my examples, but the oral callosities retain a brown or yellow stain. Sculpture: on the upper whorls are two spirals, and on the last eleven, which become closer and smaller anteriorly; the radials are stout round-backed ribs, which bulge at the periphery of the upper whorls, and are set at seven or eight to a whorl. Aperture: the mouth is triangular, contracted by a bend of the lip; sinus horizontal, spout-like, with a C section ; columella with two or three small transverse plaits; canal short, a little recurved. Length 4,8 mm., breadth 1,6 mm.

This has a general resemblance to Glyphostoma trigonostoma Hervier, but the Queensland shell is smaller, tapers more sharply to a point, is more contracted at the sutures, and has fewer spirals.

Australia: Queensland 5 to 8 fathoms; Murray Island (type) 5 to 10 fathoms; Hope Island 20 fathoms; Darnley Island 20 fathoms; off Endeavour Reef.
