Abstract

The original lot of specimens assigned to Pentagnostus praecurrens (Westergard, 1936) includes a poorly preserved, flattened holotype cephalon from Mossberga, in which diagnostic characters are difficult to discern, as well as another small cephalon and three pygidia which may be conspecific. A subsequent record of the species by the same author comprises seven specimens only one of which may belong to P. praecurrens. Others from this lot include Triplagnostus gibbus, Onymagnostus sp., Lejopyge aff. barrandei and a pygidium of uncertain affinity.
