A skull roof of the palaeoniscoid fish Haplolepis (Parakaplolepis) aff. anglica from the Lower Penn-sylvanian near Parrsboro, Nova Scotia, provides the earliest record of the Haplolepidae and the first from Canada. The subgenus ranges from middle Westphalian A to late Westphalian D. A small Gyracanthus spine confirms the survival of this acanthodian genus into Pennsylvanian time in North America. The associated fauna includes palaeoniscoids, crossopterygians, and fresh-water arthropods.Conflicting citations of haplolepid type specimens from Linton, Ohio, are pointed out, and overlooked but prior designations are noted.
