Original Description
Disk with smooth surface, six times as broad as the medullary shell. Pores regular, circular; eighteen to twenty on the radius of the disk. Margin of the disk with a broad solid equatorial girdle, which bears fifty to sixty strong conical teeth on the periphery; teeth about as long as the diameter of the medullary shell. Both opposite marginal spines cylindro-conical, 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 0.05; length of both main spines 0.2 to 0.3, breadth 0.02.

Editors' Notes
Haeckel listed Sethostylus dentatus under the subgeneric name Heliostylus, but did not include the subgeneric name in the species name.

Figure: Only the upper half of the illustrated disc represents Sethostylus dentatus. The lower half Haeckel identifies as a second figure, \fig.2\", which refers to Sethostylus serratus haeckel, 1887a."[comment from RadWorld database]
