Althougli, as Las already been said, tbe fauna of tbe Eolling Downs must bo 
treated as a whole, as must also its flora should determmable specimens bo obtained, in 
the following list the Tarious fossiliferous localities bitberto exploited are iept apart, as the 
distinction may be found to have some possible utility in the future. Tbe list is intended 
by us to correct and supersede all previously published lists. A considerable number of 
fossils are now recorded for the first time, my Colleague having carefully worked over an 
immense mass of material, which I was able to place in bis bauds, in addition to collec- 
tions made by Mr. G-. Sweet, and Mr. C. W. De Vis from Queensland, other fossils from 
the north-west corner of New South Wales in the Mining and Geological Museum, 
Sydney, and a collection obligingly forwarded on loan by Professor R. Tate, from the 
Lake Eyre Basin, South Australia. The Geological Survey Collection includes valuable 
donations of Eolhng Downs fossils by the following gentlemen: The Hon.^ A. C. 
Gregory, Brisbane; Messrs. J. B. Henderson, M. I. C.E., Hydraulic Engineer, Brisbane; 
R. Sexton, C.E., Brisbane ; J. Ealcouer, Brisbane ; the late James Smith, Rockhampton ; 
E. K. Ogg, Rockhampton; Goffage, Tambo; Rowland Morrisby, Blackall; S. 
Sharwood,Aramac; E.R.Edkins, MountCornish; Julius von Berger, Winton; G. Cramteri, 
Winton; P. E. Sellhcim, Gympie; R. Sefton, Townsville; W. Landers, Townsville; A. 
Brand, Townsville ; A. C. Macmillan, C.E., Ayr ; R. Gray, Hughenden ; J . Burkitt, 
Maxwellton, near Hughenden; J. Hugh Moor, Manfred Downs, near Cloncurry ; 
P. W. Pears, Normanton ; the Rev. T. W. Ramm, late of Hughenden ; W. L. Mackinnon, 
A.M.I.C.E., Irrigation Engineer, Brisbane ; and D. P. Ryan, Hughenden. 
Among the most interesting of these donations are portions of skeletons of 
Icldhyosaurus and Plesiosaurus (?), to which my Colleague refers in his Notes. The 
former is from the bed of the Elinders, thirty-five miles below Richmond Downs (Mr. 
J. Burkitt) ; Elinders River, at Manfred Downs (Mr. J. Hugh Moor) ; and Elinders 
River, near Glendower (Mr. V7. L. Mackinnon). The latter is from Manfred Downs 
(Mr. J. Hugh Moor). 
We are indebted to ftlr. C. W. De Vis for an opportunity of examining a portion 
of an Ichthiosaurus from Marathon Station, on the Elinders, and vertebrm of Plesiosaicrus 
from the Walsh River. The specimens are in the Queensland Museum.* These 
fossils confirm the previous determination of such genera made by Prof. McCoy, and, 
from their strong CretaciousyhcAs, assist in approximately fixing the age of the deposits 
in which they occur. 
Another very remarkable fossil is a fragment of a Ganoid fish, measuring about 
ten inches square, from Hughenden, presented by Mr. D. P. Ryan. This fish is speci- 
fically identical with that first discovered by Mr. George Sweet, of Brunswick, Melbourne, 
in the Rolling Downs, near Hughenden, and named Belomstomus Sweeti. It is described 
by my Colleague and Mr. A. Smith Woodward as “ the largest species of the Mesozoic 
Ganoid Belonostomus which has yet been found. The fish lived in the same geological 
period, in Western Europe, India, and Brazil, and the present discovery is thus of 
great interest, as extending still further the ascertained geographical range of this 
genus during Mesozoic times.” 
In the southern portion of the area watered by the Warrego, Paroo, and 
Cooper’s Creek, there is a great thickness of the “ Rolling Downs ” strata, but it is 
probable that the uppermost beds are frequently debris of the Desert Sandstone accumu- 
lated on a continental land surface during Tertiary times. In this region the thick brush- 
wood of mulga and gidyah forms a strong contrast to the open downs. This subject wdl 
he further referred to in treating of the Moondilla gold discoveries, in Chapter XXXV.
