INTRODUCTION. 
Only four species of ostracoda have been previously recorded from 
the Permian rocks of Eastern Australia. Three species were described 
from New South Wales by Chapman (1920), namely Leper ditia 
prominens from Farley and the Caledonian Shaft at Cessnock, at 
200 feet, Primitia dunii from the Caledonian Shaft and Jonesina 
etheridgei from Farley, and one Entomia jonesi by de Koninck (1898) 
from the Muree Sandstone. The genera Bairdia, Healdia and Cavellina 
were recently recognised by the writer in samples of ‘ ‘ Fenestella Shale ’ ’ 
from an open cut on Barossa road which joins Lenah Valley with 
Tolossa Street, Glenorchy, Tasmania, but the specimens were too poorly 
preserved for specific determination. Considerable investigation has 
been carried out on the ostracoda in America and the well illustrated 
publications form an excellent basis for comparison with the Australian 
forms. 
The species herein discussed are from the Kulnura Bore, parish 
Kooree, county Northumberland, and from surface samples from the 
Hunter River District in New South Wales, and from surface sections 
in the Springsure area in Queensland. All the ostracoda are associated 
with a typical foraminiferal assemblage, including Hyperamminoides 
acicula . Parr, Calcitomella stephensi (Howchin), Frondicidaria 
woodwardi Howchin, F. parri Crespin and Geinitzina triangularis 
Howchin. 
The following new species of ostracoda are described: Bairdia 
grayi, Bairdia nyei, Healdia chapmani, Cavellina spring surensis, 
Cavellina aequivalvis, Cavellina kidnwraensis and Basslerella australae. 
All specimens are in the Commonwealth Palaeontological Collection 
at Canberra. The plate accompanying the paper has been prepared 
by Mr. F. Canavan, M.Sc., of the Mineral Resources Survey.
