This species is very common in the southwest Pacific, particularly in Indonesia and the Philippines. Like the previous species, the shell is typically monochromatic black or red-brown on white, however this species is strombiform rather than ovate and has a
lilac stain around the aperture edge, which is markedly thickened at the middle and denticulate. The shell is unsculptured, and is similar to Euplica, though it lacks columellar folds. Adults are 10 to 15 mm long, with 5 to 7 teleoconch whorls and are often heavily eroded, even if collected live. The protoconch has 1.75 to 2 smooth whorls; these may be white or coloured and patterned like the teleoconch.
Specimens collected by the expedition varied in colour and pattern. The most common pattern was small round white spots on red-brown or black, however a few specimens had zigzag axial white stripes rather than spots, and some intermediates (axially elongated spots) were also present. Specimens were collected from eight stations, all intertidally, on and under rocks and on mangroves.
