Murex radula: Shell small, fusiform, Colour cream, spines orange, columella pale lilac. Whorls seven. Sculpture: eight feeble varices alternating on each whorl. On the third and fourth whorls they are proportionately much stronger and are angled at the periphery. The body whorl has eleven spiral cords, narrower than their interstices; both are overridden by fine lamellae in the line of growth. At frequent intervals these cords produce small, short, tubular, orange spines, which lend a conspicuous and recognizable aspect to the shell. Apex of three whorls conical, smooth, and glossy. Aperture simple, lip sharp, canal broad and open. Length 9, breadth 4 mm.
