The new tropidocoryphid trilobite genus Cirriticeps (Proetida) from the Silurian of New South Wales DAVID J. HOLLOWAY Museum Victoria, GPO Box 666, Melbourne, Victoria 3001, Australia; email The new tropidocoryphid genus Cirriticeps is represented in the Silurian of New South Wales by two species, one of them from the Wenlock to Ludlow of the Orange district, and the other from the upper Ludlow of the Yass Basin. The genus is most closely related to Tropidocoryphe, known from the Lower and Middle Devonian of Europe and North Africa, and was probably ancestral to it. The two genera are characterised, amongst other features, by very broad anterior and lateral cephalic borders that are poorly differentiated from the genal field and carry a strong epiborder furrow. The structure of the borders has been misinterpreted previously in Tropidocoryphe, the epiborder furrow having been regarded as the border furrow, and the inner part of the border as part of the genal field. Cirriticeps differs from Tropidocoryphe mainly in having deep longitudinal glabellar furrows extending from the occipital furrow to S3, numerous fine tropidial ridges on the genal field instead of a tropidium, eight instead of nine thoracic segments, and no median spines or spinose nodes on the posterior edges of the occipital and axial rings. .
