Abstract
A new species of olenid trilobites, Olenus henningsmoeni n. sp., is de scribed from the Upper Cambrian Olenus/Agnostus (Homagnostus) obesus Z one of Kinnekulle and Billingen in Vastergotland, Sweden. It is closel y comparable to O. gibbosus and O. transversus, but differs in having 19 thoracic segments with long pleural spines. The large number of tho racic segments may indicate that it was derived by peramorphosis. A sp ecies of Parabolina from the Olenus/Agnostus (Homagnostus) obesus Zone is figured.
