Original Description
Cephalis large, hemispherical, distinctly trilobed, with dense, irregular, polygonal network. From the centre of its top diverge three stout arches or semilunar rods, which are curved downwards, and unite with the three horizontal, radial beams of the collar-septum inside the collar-ring. These three parietal arches of the cephalis are much stronger than in the similar preceding species (Pl. 57, fig. 9), and between them are placed three vaulted bosoms of the cephalis. The collar-ring and the thorax are of the same form as in the preceding, but possess only four concentric, nine-angled rings.
Size: Cephalis 50µm long, 80µm broad; thorax 240µm diameter.
Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Sethophormis triloba under the subgeneric name Enneaphormis, but did not include the subgeneric name in the species name.
[The \similar preceding species\" refers to Sethophormis rotula Haeckel, 1887a.]"[comment from RadWorld database]
