Original Description
Mitral ring smaller than the basal, both rings elliptical, with curved rods. Sagittal ring ovate, prolonged upwards into an occipital horn, downwards into a caudal foot, as in the preceding species. As in the latter, also, the two lateral columellae are prolonged downwards into two pectoral feet, but also upwards into two convergent horns, which are united with the occipital horn (commencing the formation of a galea). Rings and feet somewhat thorny.

Size: Diameter of the cube 0.16; total height 0.2.

Editors' Notes
Haeckel listed Acrocubus cortina under the subgeneric name Tripocubus, but did not include the subgeneric name in the species name.

The \preceding species\" refers to Acrocubus lasanum Haeckel, 1887a.

see also p.891: It is clear from the family discussion ofTympanida (pp.987-990) that Haeckel meant to assign the following key to the letters in the illustration not already mentioned in the explanation of p.891; q = frontal or lateral ring; h = horn; s = horizontal basal ring; m = horizontal mitral ring."[comment from RadWorld database]
