This study was based on all the material of Pagetia from the Middle Cambrian strata of Quebec, British Columbia, and Idaho available in the U.S. National Museum and the writer's collections. Seven previously described species, 3 new ones (P. quebecensis, P. rugosa, and P. walcotti), and a new subspecies (P. billingsi inermis) are described and figured. A Lower Cambrian form from British Columbia is figured but left unnamed. Only two species from the Lower Cambrian of New York are taken into conssideration, since they were adequately described and illustrated.
