Abstract
New species of linguloid shells, Ectenoglossa brunnschweileri, Obolus mootwingeensis and Lingulella (Leptembolon) gnaltaensis, are described and figured from Lower Ordovician (Tremadoc) rocks of the Gnalta Stage in the West Darling District of New South Wales. Recent palaeontological evidence of the age of the Mulga Downs Formation, East Darling District, previously correlated with the Mootwingee Series, is also mentioned. New species of Lingula are also described and figured from various Upper Silurian and Devonian localities.
