Shell small, imperforate, broadly conical, pale reddish-yellow with small white blotches ; whorls six and a-half, slightly imbricating; base almost flat. Ornament of penultimate whorl consisting of three spiral line crossed by equal-sized, stout, slightly obtuse, oblique ridges ; the interstitial pits deep, rhombic, smooth ; the points of intersection of the spirals and oblique costae are produced into spiniform granules. The line diminish in size from the anterior to the posterior suture ; the oblique ridges being as stout as the median spiral. The spiral ridges on the body-whorl are increased by a slender lira interposed between the first and the second, and by a subperipheral lira nearly equal in size to the peripheral one, the two together forming a truncated sulcated keel. Base with about six concentric line, somewhat depressed, subacute, and showing a tendency to subgranulose, crossed by strong radial growth-lines. Dimensions.—Height, 5 ; basal diameters, 4 and 4,5.

Trellised, and set as it were with prickles, this species resembles Calliostoma rubropunctatus A. Adams, from North Australia, but differs by its subimbricating whorls and fewer lirae. Both holotypes have similar peculiar red dotting in the pits between the costae.
