Rank: genus
Type species: Cyrtophormis armata Haeckel 1887 [designated by Campbell,1954, p.D139]
Described on page(s) : 1459
Family (traditional): Artostrobiidae

Current identification/main database link: Cyrtophormis

Original Description

Stichophormida (vel Stichocyrtida multiradiata aperta) with ovate or spindle-shaped shell, without lateral ribs. Mouth constricted, with a corona of terminal feet.



From the Greek cyrtophormis = plaited-basket"

Extra details from original publication
The genus Cyrtophormis may be derived from the preceding Artophormis by reduction of the lateral ribs, whilst the terminal feet (as their free prolongations) remain, and form a corona around the mouth. Sometimes also each constriction bears a corona of spines. It corresponds to Calocyclas among the Tricyrtida and Anthocyrtis among the Dicyrtida.
