Abstract

This Bulletin describes the trilobite fauna of the Gala Beds, an informally designated stratigraphical unit of late Upper Cambrian age outcropping along the Momedah anticline in the Boulia area, western Queensland. On the basis of their triolobites the Gola Beds are provisionally considered correlatives Franconian to early Trempealeauan interval of North America, and of the Fengshanian of north China, Korea, and Manchuria. Of the 19 genera described below, 10 are new; and of the 25 species, 21 are described for the first time and four are left under open nomenclature owing to lack of material. New taxa are: Pseudagnostus papilio sp. nov., P. clavus sp. nov., Connagnostus junior sp. nov., Distagnostus ergodes gen. et sp. nov., Rudagnostus avius sp. nov., Geragnostus (Micragnostus) acrolebes sp. nov., Richardsonella laciniosa sp. nov., R.(?) kainelliformis sp. nov., Sigmakainel/a translira gen. et sp. nov., S. longilira sp. nov., Kaolishania australis sp. nov., Mansuyites [utilijormis gen. et sp. nov., Palacorona bacculata gen. et sp. nov., Lophosaukia torquata gen. et sp. nov., Eoshumardia cylindrica sp. nov., Del/ea(?) laevis sp. nov., Lorrettina macrops gen. et sp. nov., Crucicephalus ocel/atus gen. et sp. nov., Duplora clara gen. et sp. nov., Golasaphus momedahensis gen. et sp. nov., and Atopasaphus petasatus gen. et sp. Novo Although the fauna is largely new, about one-third of it has affinity with species previously described from North America, notably the pseudagnostinids, richardsonelIinids, and the ptychoparioids Del/ea(?) and Lorrettina. A further third has affinity with east Asian species, in this case the Kaolishaniidae, Saukiidae, and Shumardiidae. Only some agnostids show much affinity with trilobites from South America, Europe, and the USSR.
