Both opposite marginal spines spindle-shaped, about as long as the diameter of the disk, and as broad as the girdle.

Editors' Notes
Haeckel listed Sethostylus serratus under the subgeneric name Heliostylus, but did not include the subgeneric name in the species name.
Figure: Only the lower half of the illustrated disc represents Sethostylus dentatus. The lower half Haeckel identifies as a second figure, \fig.1\", which refers to Sethostylus dentatus haeckel, 1887a."[comment from RadWorld database]
