Shell of moderate size, 15 - 33 mm., claviform, with a tall spire and truncated anterior end, but without a definite parietal tubercle, except for a thickened callus in a gerontic state. Protoconch of 2 1/2 smooth whorls, usually developing a weak low-set keel towards its termination, which is defined by a forwardly projected weak axial growth line, followed by numerous weak axials, gradually increasing in strength along the spiral keel as the post-nuclear sculpture develops. Sinus rather shallow, with a broadly rounded apex, occupying the middle of the shoulder slope, not subtubular, constricted or ridge-margined. Adult sculpture of axials crossed by spirals in varying strengths, usually into peripheral nodes or pointed tubercles, in single or double series. Outer lip not varixed; anterior canal very short and shallowly notched. Operculum leaf-shaped, with a terminal nucleus. Range — Recent, New South Wales, Victoria, Tasmania, northern New Zealand and Indo-Pacific, Mauritius, East Indies, Philippines and Loyalty Islands.
