Original Description

Cephalis quinquelobate, with five cylindrical slender curved tubes, three of which are placed in the sagittal plane (a superior apical, a posterior caudal, and an anterior sternal), whilst the other two are paired and diverge laterally (two pectoral tubes). The five tubes correspond exactly to the five typical spines of Stephanium (p.952). The helmet-shaped occipital lobe of the shell is twice as large as each of the two anterior frontal lobes, and three times as large as each of the two lateral buccal lobes. Pores numerous.

Length of the shell 0.07, basal breadth 0.04. [dimensions in mm]

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Although Haeckel does not explicitly assign Cannobotrys pentacanna to the subgenus Cannobotrusa, it is clear from the discussion of the genus Cannobotrys that Haeckel intends this assignment.
