1900 Anthocyrtium anthemis Haeckel (?) Cleve p. 6, pl. 3, fig. 12
Catalog entries: Anthocyrtium anthemis
Original description: Shell papillate, with obliterated collar stricture. Length of the two joints = 1: 3, breadth = 1: 3. Cephalis hemispherical, with very small and scarce pores, and a conical horn of the same length. Thorax conical, as long as broad, with conical papillæ, and eight to ten transverse rows of roundish pores, gradually increasing in size downwards. Mouth scarcely constricted, with fifteen to twenty divergent, straight, conical feet, half as long as the thorax.
Remarks on original description: There was no illustration of this species in Haeckel (1887)
Haeckel listed Anthocyrtis anthemis under the subgeneric name Anthocyrtarium, but did not include the subgeneric name in the species name.[comment from RadWorld database]
The original concept of Anthocyrtium Ehrenberg included both theoperid and pterocorythid cephalic forms. Anthocyrtidium is in modern usage a pterocorythid genus, and, as the type species mespilus of Anthocyrtis has theoperid cephalis anthemis is in the database placed in Anthocyrtis- dbl

Published descriptions
As there exists no figure of this species, I am somewhat uncertain about the identification. I have seen a single specimen only, which was found alive at 63 degrees N, 2 degrees E (March 1898), where it occurred together with some species of the tricho-type. The description in Haeckel's Monograph (Chall. Rep. page 1273) agrees well with my specimen, but the dimensions are somewhat dissimilar. On my specimen the cephalis was 0.02 mm long and broad and thorax 0.05 long and 0.1 broad. Haeckel's species was found in the abysmal depths of the northern Pacific. If my species really belongs to Haeckel's species, the occurrence above the deepNorske Rendeis a fact of considerable interest.
