Description
Trilobate, with L-2 smallest lobe, rarely projecting above hinge line, marginal ridge or frill developed in some species, surface commonly granulose or pitted, female with globular to subovate anteroventral pouch. [In the opinian af BERDAN, the generic names published by HENNINGSMOEN (1954) are desirably used far subgenera af Bey,·ichia. Possibly Velibeyrichia, which includes most North American species assigned to Beyrichia, should have the status of an independent genus. -MOORE.]
