Somewhat similar to C. pyrrhostoma but differs from it in its more rugose sculpture and the possession of a concentric operculum. The shell is chalky white, umbilicate and the last whorl is usually keeled.

The animals are characterised by a deep furrow on each side of the head, and a suprapedal fold around the sides of the foot. Movement is by steps. The snout is long. The eyes have a cluster of glands above them. Coxiella are dioecious. Development is direct. Females are oviparous, depositing eggs singly in capsules coated in sand or mud.
