Diagnosis
ReferenceDiagnosis
A. R. Ormiston 1967Glabella wider than long, tapering rapidly anteriorly with a constriction opposite the 2p glabellar furrow. In longitudinal and transverse profiles the glabella is fiat and low lying. Three pair of equally deep lateral glabellar furrows. On either side of the glabella anterior to the 3p furrow a conspicuous node occurs in the axial furrow. These nodes occupy the position at which anterior pits are located in trilobites which have those structures. Glabella punctate. Occipital lobes well developed. In transverse profile the pygidial axis has only a slight independent convexity barely interrupting the curvature of the pleural fields. On the internal mould the axial rings are truncate at their crests. Pleural ribs have almost no relief in cross section.
