Observations . — The specimens of G. triangularis figured in this paper 
are from material from Pokolbin, the type locality for the species, 
collected by Dr. G. D. Osborne for Oil Search Ltd. They illustrate the 
megalospheric and microspheric forms of the species. The microspheric 
form is longer than the megalospheric and the chambers in the early 
stages are very small and numerous. In another microspheric specimen 
which is incomplete a terminal spine is present in the earliest portion. 
All tests are well polished. Length of topotypes: (a) 1.01 mm,; 
( b ) 0.73 mm. 
Occurrence . — Topotypes (Comm. Pal. Coll. Nos. 284, 285) : 
(a) microspheric, (6) megalospheric — Pokolbin, Hunter River District, 
New South Wales (Lower Marine Series). 
Other Localities. — Queensland. Lower Bowen Series: North bank 
of Cattle Creek, 14 miles S.E. of Springsure; Cattle Creek below 
Waterfall, near Springsure; Mt. Hope, 20 miles S. of Springsure; 2.5 
miles from Mantuan Downs, on Springsure road; 3 miles from Cracow 
on road to Theodore.
