According to Bartsch (1943: 83–84), broadly conic shell, protoconch 2½ whorls, the last with closely spaced hair-like axial threads, teleoconch with strong axial ribs, weak in the anal sinus, evanescent on the shell base. Ribs are overridden by axial striae and crossed by strong spiral threads, about the same distance apart as their interspaces, imparting a screen-like texture to the shell surface. The anterior fasciole has stronger spiral than axial threads. The outer lip has a weak stromboid notch and a strongly channeled anal notch; the anterior canal strongly channeled. A heavy varix lies about ⅓-turn behind the edge of the outer lip. The inner lip is appressed to the columella and forms a knob on the parietal wall at the junction with the outer lip.
