Periostracum thin, fibrous, pale brown. Locality: 290 56' S. 310 iaj' E., 200 fathoms (off Durban). Fisheries Survey Station K220. Two dead, both with hermit crabs. 39 X 16 mm, nucleus of protoconch missing, 7 whorls. 47 X 17 mm, protoconch plus 7 whorls. Remarks: Very close to formosissimum Tomlin, but the whorls are more angulate, less carinate at the periphery, the axial ribs are better developed

Remarks: Very close to formosissimum Tomlin, but the whorls are more angulate, less carinate at the periphery, the axial ribs are better developed above the periphery, the peripheral lobes become fewer on the later whorls instead of increasing in number (12 to 10, instead of 8 to 11), the subperipheral angulation on the body whorl has 3 fine lirae instead of 2 (or only one) prominent lirae between the prominent keels. The shell is thus less pagoda-like. Proportionally broader than angulare Barnard, 1959, and without the prominent spiral lirae of radiale (Watson, 1882 & 1886)..
