Diagnosis
Reference | Diagnosis | |
---|---|---|
C. E. Resser 1936 | Cephalon semicircular ; glabella well defined, tapered, with glabellar furrows. Eyes lacking. Fixed cheeks large, apparently extending to the lateral margins. Marginal furrow extends entirely around the cephalon. Rim generally of even width but sometimes slightly expanded in the middle. Preglabellar area always present and exceeds that of Conocoryphe.
Thorax and pygidium typical of the family. Surface rarely smooth but usually pustulose or lined or both. Usu- ally a ridge or vein extends outward across the cheeks from the dorsal furrow, arising near the front of the glabella. This ridge occupies the position of, and resembles, an eye line, but in some species it is more like a vein branching as it advances. Anterior to this ridge the system of surface ornamentation characterizing the species gives way frequently to lines or veins. |
