Shell small, smooth, ovate. Colour white, irregularly longitudinally striped by narrow, brown, broken lines, which are interrupted at the periphery. Whorls seven, slightly rounded, glossy, traversed by a few, scarcely perceptible spiral-grooves. Aperture narrow, outer lip straight, simple, not grooved within. Columbella arcuate above, denticulate below. Length 4,5 mm, breadth 1,75 mm.

This species was originally recognized from Funafuti in the Ellice Islands. It is similar to P. delineata but has a different colour pattern. Sleurs (1987) has it as a synonym of P. abyssicola (Brazier, 1877), but the color pattern is quite different. The upper part of each whorl in this species has narrow, widely spaced axial brown lines around large, rectangular unpigmented spaces. The lower part of the body whorl has spiral rows of thicker axial lines, interrupted axially in several series. There are two rows of opaque white spots at the suture level. P. delineata does have unpigmented spaces close to the suture, but they are much smaller, and the lower row of brown markings is not broken up into series. The shell is tall and narrow, biconic, 4 to 6 mm long with 5 to 5.5 teleoconch whorls, and a broadly conical protoconch of 3.5 to 4 whorls. The protoconch may be white, pink, or unpigmented, and has a midline spiral cord.
