Original Description

Both proximal chambers nearly ellipsoidal, with regular, circular pores enclosed by hexagonal frames. Both distal chambers conical, with a circle of ten to twelve large square pores at the base; the other pores small, roundish. The cortical shell of this species is quite the same as that of Panartus amphiconus (Pl. 40, fig. 5), but differs in the absence of the external envelope (or the second cortical shell), and is covered with short, conical spines on the whole surface.

Total length of the cortical shell 0.25, greatest breadth (on the base of the distal chambers) 0.12; meshes of the proximal chambers 0.008, of the distal chambers 0.004; bars 0.002 to 0.04, spines 0.01 to 0.02. [dimensions in mm]

Etymology:
Latin spinosus -a -um = spinous

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Panartus spinosus under the subgeneric name Panartura, but did not include the subgeneric name in the species name.

Description: Haeckel here compares Panartus spinosus with Panartus amphiconus, pl.40, fig.5. The species illustrated on pl.40, fig. 5, however, is Peripanartus amphiconus, which is probably the species Haeckel intended.
