PALAEONTOLOGICAL NOTES. 
249 
A still larger specimen of an ilium in the Museum collection, for which we have no 
precise locality, shows that the freshwater Chelonians of the past w r ere giants 
compared with those of to-day. 
Some half-a-dozen very fragmentary shards from Messrs. Zeller Brothers 5 series 
cannot be satisfactorily identified. 
F. Chapman has referred a fossil cast of a tortoise found in a bed of ironstone 
at Carapook, Victoria, 6 to the genus E7nydura, and Lydekker has recorded both 
Etvydvra and C'helodina from Australia. 7 
Pallimnarchus pollens De Vis. 
This extinct crocodile is represented by an incomplete tooth and two fragments 
of scutes (F. 2118). 
Fish Remains. 
These consist of two anterior dorsal spines. One of these (F. 2120) has a 
serrated anterior edge and appears to be allied to the common “ freshwater catfish 55 
or “ dewfish, 55 Tandanus tandanus. In the Museum collection there are two other 
spines from Chinchilla (F. 16-1180) which have been registered as Tandanus sp., 
but which are considerably larger than the spines of the present-day species. 
The other dorsal spine from Brigalow has been tentatively recorded as 
Oligorus sp. (F. 2122). In our old collections we have several fossil specimens from 
the Darling Downs which represent a fish allied to or identical with the Murray Cod 
of to-day, Oligorus macquariensis. 
RHCETOSAURUS BROWNEI. 
(Plate XXIX.) 
Opportunity is taken to illustrate the remains of the Queensland Jurassic 
Dinosaur Rhoetosaurus brownei as now on exhibition in this Museum (Plate XXIX., 
figures 1 and 2). A large painting in oils, showing the probable appearance in life 
of these giant herbivorous Dinosaurs and the characteristic vegetation of the period, 
has been placed above the fossils. Owing to the incompleteness of our material 
this has been largely based on the reconstructions of Ca marasau r us , an allied 
American form, by E. S. Christman in the American Museum of Natural History. 
The artist. Mr. Douglas 8. Annand, has put some excellent work into our painting. 
His Excellency Sir John Goodwin has also given assistance by providing a striking 
little sketch showing the relative proportions of a modern horse and the giant 
Dinosaur. 
In addition to the detailed description of this fossil in our Memoirs, 8 a popular 
account of Rhoetosaurus brownei was published in “ The Australian Museum Magazine, 55 
vol. iii, July- September, 1927. In this article a photograph by Mr. L. C. Ball,
