Abstract: | The Agnostida are the most important part of the fauna of the Abbey Shales, which is the best-known middle St David's (Middle Cambrian) sequence in Britain. Revision of Illing's (1916) collections allows a correlation of the Paradoxides hicksii fauna with Westergaard's (1946) Ptychagnostus atavus-Tomagnostus fissus Zone, and the Paradoxides davidis fauna with Westergaard's Hypagnostus parvifrons Zone and Ptychagnostus punctuosus Zone (based on the Swedish sequence). A Metadiscus sp. is described. Six species of Condylopygidae are discussed, of which three show a pygidial ‘fringe’. Eleven species of Quadragnostinae, three of Ptychagnostinae (one showing a hypostome), and four of Tomagnostinae (including young growth-stages) are illustrated or discussed. Two species of Diplagnostidae, one species of Phalacroma and two of Phalagnostus are illustrated. |
