Diagnosis
Reference | Diagnosis | |
---|---|---|
C. E. Resser 1936 | All features normal for the family. Cephalon and pygidium like Bailiella except for the rim of cephalon. Rim thickened and extended backward in the middle, sufficiently in some species to connect the anterior furrow with the dorsal furrow.
Some species were referred to Ctenocephalus because the thickened rim simulates a median boss, but examination of the specimens shows at once that the structure is quite different. |
