Original description: Shell conical-campanulate, with two distinct strictures. Length of the three joints = 2: 8: 1, breadth = 2: 8: 10. Cephalis hemispherical, with three divergent, conical horns (the caudal horn, directed downwards, much longer than the occipital and frontal borns). Pores of the thorax large, roundish. Abdomen (as in the two preceding species) with only a single circle of forty to fifty small square pores. Coronal with about the same number of short, triangular, almost horizontally divergent feet.

Length of the three joints, a 0.02, b 0.08, c 0.01; breadth, a 0.02, b 0.08, c 0.1. [dimensions in mm]
Remarks on original description: Haeckel listed Clathrocyclas semeles under the subgeneric name Clathrocycloma, but did not include the subgeneric name in the species name.

Description: "two preceding species" refers to C. alcmenae and C. europa in Haeckel, 1887a.
