Original Description
Forme dont le céphalis porte deux cornes équivalentes obliques sur l'axe d'allongement. Les cornes sont triradiées sur toute leur longueur. Le squelette céphalique comporte les actines A, V, MB, Ll, Lr, ll et lr. L'actine D est absente. A proximité de la paroi les actines sont plus ou moins nettement bifurquées. Les actines Ll, Lr, ll et lr sont grossièrement situées dans un même plan par rapport auquel l'actine V est nettement oblique. Extérieurement le céphalis est souvent imperforé du fait d'une deuxième couche siliceuse car, intérieurement, des amorces de pores sont visibles. Prolongeant le céphalis distalement, le vélum à paroi épaisse, est percé de pores régulièrement disposés; régulièrement évasé ou possédant des constrictions il peut porter des épaississements annulaires.


Translation: Form with a cephalis having two equivalent horns oblique on the long axis. Horns with three grooves along their total length. Cephalic structure with spines A, V, MB, Ll, Lr, ll and lr. No D spine. Towards the wall, spines more or less bifurcated. Spines Ll, Lr, ll and lr roughly lying in the same plane, to which V spine is clearly oblique. Cephalis externally imperforate due to a secondary siliceous layer, pores internally apparent. Growing out from the cephalis, a thick velum is perforated by regularly distributed pores, progressively flared, or with strictures; the velum can present annular swellings. In French. Translation by J.P.C.]]

Etymology: From the Latin cuniculus, -i, rabbit + formis, shape. By analogy with a rabbit head.

Editors' Notes
Ce genre à un seul segment se différencie de tout autre par son vélum et ses deux cornes caractéristiques.

[This single-segmented genus differs from all others by the velum and the two characteristic horns.]

Stratigraphic range: Lias, Jurassic, Mesozoic.
