Original Description
Shell slender, pyramidal, with six sides and two slight strictures. Length of the three joints = 1: 4: 12, breadth = 1: 4: 8. Cephalis subspherical, with a conical horn of twice the length. Thorax conical, with regular, circular pores. Abdomen truncate, pyramidal, with six strong, divergent, straight ribs, which are connected by five to six transverse, hexagonal rings; therefore six longitudinal rows of large, roundish, quadrangular meshes (four to five meshes in each row). Mouth hexagonal.

Length of the three joints, a 0.025, b 0.1, c 0.3 ; breadth, a 0.03, b 0.1, c 0.2.

Editors' Notes
Haeckel listed Cycladophora pyramidalis under the subgeneric name Lamptidium, but did not include the subgeneric name in the species name.
