the strong resemblance of the typical forms of Productus to the characteristic P. 
Oi'ridus of the Magnesian Limestone and Zochstcin. This subject was fully discussed 
my account of “ A Collection of Possils from the Powen Elver Coal Pield, &c.,* 
^’Jierein I concluded as follows;— “ The examination of these Bowen Elver fossils, so far 
it has gone, leads me to regard them as occupying a high position in the Palaeozoic 
6rios ; and that aU purposes would best be served by regarding them as of Permo- 
^rboniferous age.” This view has gained strength, the more the facts have been 
investigated, and I am now anxious to extend the adoption of this term to the whole of 
® similar formations in K’cw South Males. 
One of the most important points of difference between the Carboniferous Scries 
° Europe and the coal-bearing rocks of Eastern Australia lies in the almost entire 
n seiice of Lycopodiaceous plants from the latter, above a certain horizon very low in 
he series. The place of this division of the Vegetable Kingdom is taken by the fern 
ossopiefig^ and the continuity of the whole strata, now proposed to be termed leimo- 
arboniferous, both in New 8outh Wales and Queensland, is shown by the passage of 
"1* genus from the Middle to the Upper Bowen Eormation and its persistence therein.t 
The strata of the Oakey Creek Coal Field, Cooktown, contain Olosnopteris, and are 
^gardod by Mr. Jack as the equivalent of the Upper or Freshwater division of the 
"Owen Series. The Little Elver Coal Field beds near Palmerville, and those of Stewart’s 
veek near Townsville, are in the same category. It will be noticed that throughout the 
orizons regarded as the equivalents of the Upper Bowen Formation there is an^ entiio 
Sallee of the genera Tcejiioptevis and ThhiTiJcldia^ both of "which become eminent y 
IJoaracteristie of the Mesozoic Coal Measures described later on. It seems more than 
Pi’obable that the occurrence of these genera will afEord a reliable basis, not only in 
Weensland, hut equally so in New South Wales, for the separation of those strata 
I am desirous of terming Permo-Carboniferous, from the still higher series, a 
ion of which, at least, are clearly of Jurassic age. 
^Vith the elaborate classification, extending from the Trias to the Jurassic, pro- 
P°sed^ by the Eevd. J. B. Tenisou Woods,j; or tbe still more beautifully fitting strati- 
fii'apbical tabulation devised by Prof. 0. Fei8tmautel,§ I cannot at tbe present moment 
incide. No fossil organic remains are so deceptive or unsuitable for determining 
.^'lostions of equivalent stratigraphy, as plants, and we know too little, not only of tbe 
|.y*^^^^Ees of fonnatious in tbis quarter of tbe globe, but also of their organic contents, 
WaiTant speculations of this kind. That we have bods of Triassic ago, and others 
^bain representing some portion of the Jurassic, is probably the case, but it is impossible 
into minute stratigrapbical subdivisions yet, on the mere chance of statements 
Innately proving correct.
