Diagnosis
ReferenceDiagnosis
A. R. Palmer 1954Cephalon subsemicircular in outline; posterior margin straight; distinct genal spines extend backward from posterolateral corners. Cranidium with glabella moderately well to poorly defined by dorsal furrow, extended to anterior margin, slightly expanded forward or of nearly constant width. Glabellar furrows shallow or absent; when visible, four pairs usually present. Occipital furrow shallow. Occipital ring flat, unspined. Border absent. Brini, when present, nar- row, only at sides of glabella. Fixed cheeks about one- half width of glabella; palpebral lobes long, poorly defined; anterior ends nearly touching dorsal furrow, posterior eads about opposite occipital furrow. Poste- rior limbs narrow, about as long as occipital ring; marginal furrow shallow.
Free cheek with evenly rounded margin and prominent genal spine. Border differentiated from ocular platform, variable in width.
Thorax of 7 or 8 segments. Axial lobe prominent, width equal to or less than that of pleural lobes. Pleural lobes of each segment subequally divided by pleural furrow. Segments terminate distally in short, sharp spines.
Pygidium subsemicircular in outline about as large as cephalon. Axial lobe prominent, tapered slightly posteriorly, reaching to or onto broad, flat or concave border. Furrows on axial and pleural lobes shallow or absent.
