B oulders of late Cambrian age in conglomerates in Quebec and Newfoundland have been intensively collected and have yielded some 18 species which were referred by Ludvigsen et al. (1989) to either Theodenisia Clark, 1948, or to Peracheilus Ludvigsen,

Previously unstudied and earlier-known specimens have revealed the wide cephalic doublure and median ventral suture in Stenopilus; the hypostome is unknown but was probably natant. The cranidium of S. pronus differs from that of the type species S. i

Plethopeltis armatus , and species of Leiocorpyphe , are shown to have in common a median ventral cephalic suture and thoracic axial rings with a poorly-defined articulating furrow and a strong transverse ventral ridge. In other characters they diffe
