Original Description
Disk with smooth surface, four times as broad as the medullary shell. Pores regular, circular; fourteen to sixteen on the radius of the disk. Margin with a broad solid equatorial girdle, which bears forty to fifty strong conical teeth on the periphery; teeth about as long as the radius of the medullary shell. Both opposite marginal spines spindle-shaped, about as long as the diameter of the disk, and as broad as the girdle.

Size: Diameter of the disk 0.3, of the medullary shell 0.075; length of both main spines 0.2 to 0.3, breadth 0.03.

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]
