In the Permo-Carboniferous System there are twoseries in which this flora is present, viz. :—The Lower *Proc. Roy. Soc. Vic, xvi (ii), 1904, p. 306. 10 QUEENSLAND FOSSIL FLORAS Coal Measures and the Upper Coal Measures, the two beingseparated by a series of marine deposits. It does not seempossible at present to separate the two series of CoalMeasures by their floras, nor can we say just which formsoccur in each Series, but there is no doubt of the presenceof the typical Glossopteris Flora in Fig. 2—Map showing approximately the distribution of the Glossopterisflora. (Mainly after David White). The name Permo-Carboniferous in Australia aroseunder a misapprehension, and there has been considerablediscussion during the past few years as to the advisabilityof discarding it. There is a more or less general agreementthat the term is not a good one, but the difficulty lies infixing the dividing line between Carboniferous and is possible that the lower portion of the so-called Permo-Carboniferous System may be Carboniferous, but the faunasof the Lower and Upper Marine Series are very similar toone another, and both are very different from theCarboniferous fauna in Eastern Australia ; in addition,the floras of the Lower and Upper Coal Measures can BY A. B. WALKOM 11 hardly be separated from one another, and there is reasonto regard the Upper Coal Measures as Permian in age. Toabandon the term , Permo-Carboniferous befor
