Abstract

This thesis embodies research into trilobites of the family Phacopidae from a number of localities within the Rora Slate and its equivalents of the late Upper Devonian of South-west England. ll phacopid species including 1 new species, 3 new subspecies, 3 uncertain new species and 1 uncertain new subspecies have been described. They are Phacops (Omegops) sp. B, Phacops granulatus (Munster), Phacops wedekindi occidentalis n.ssp., Phacops wedekindi microps n.ssp., Phacops wedekindi ssp. A, Cryphops? wocklumeriae lounstonensis n.ssp., Crypliops? ensae (R. & E, Richter), Cryphops sp. A, Dianops limbatus (Reinli. Richter), Dianops griffitiiides griffithides (R. & E. Richter), Dianops tripartitus (Thomas), Dianops combensis n.sp, and Dianops sp. A. Among the new features noted in these phacopids are, the spine like mesial tubercle of Phacops wedekindi occidentalis, the functional facial sutures of Cryphops? wocklumeriae lounstonensis and Dianops tripartitus, the secondary eyes of Dianops tripartitus and the transitory pygidium of Dianops sp. indet.. Juveniles of Phacops wedekindi occidentalis, Cryphops? wocklumeriae lounstonensis, Dianops griffithides griffithides, Dianops tripartitus and Dianops sp. indet., some new to palaeontology, have also been described.
