New material of Onycopyge liversidgei Woodward, from the Upper Silurian in the vicinity of the type locality at Quidong. New South Wales, permits the clarification of the morphology of the genus and its assignment to the Subfamily Deiphoninae. Another occurrence of the genus in Ludlovian rocks at Canberra is reported. Two types of pygidia at Quidong suggest that the species may be sexually dimorphic. Evidence is produced in support of the view that members of the Deiphoninae were benthonic.
