Colus pulcius is a species of sea snail, a marine gastropod mollusk in the family Colidae, the true whelks and the like.

[1] (Original description as Colus (Aulacofusus) capponius ) The shell is of moderate size and its height measures 40 mm.

The axial sculpture consists of fine silky incremental striae, sometimes with a tendency to cause wrinkles near the suture.

The spiral sculpture consists of (on the penultimate whorl about 17) regular narrow rather deep grooves with much wider flattish interspaces, uniformly covering the whole surface of the shell.

The outer lip is retroactively arcuate behind and protractively anteriorly, not reflected.
