other witli the pyroxene andesites by the characteristically 

 soiled basic plagioclase, while the Martin's Greek andesite, 

 with its almost unzoned andesine, and its hornblende and 

 biotite, occupies a conspicuously intermediate position, 

 which suggests, as does its field occurrence at the base of 

 the series, that it may represent the original magma from 

 which the extreme types were derived by differentiation. 



Part II. 

 Glaciation Sequence and Correlation of the Permo- 

 Carboniferous and of the Kuttung (mostly Middle Carboni- 

 ferous) Strata of New South Wales, by Professor T. W. 

 Edge worth David. 



(A) The correlation of the Burindi Series (Lower Car- 

 boniferous) which underlies conformably the Kuttung will 

 be fully discussed in a paper about to appear in the Proc. 

 Linn. Soc. N. S. Wales, by Prof. W. N. Benson, d.Sc b.a., 

 (research Cantab.) His conclusion that the Burindi Series 

 is probably of Visean age is quite in accord with those of 

 my co-author and myself. We hold that the Burindi strata 

 with their extraordinary development of crinoids, their 

 characteristic brachiopod Syringobhyris exsuperans, their 

 trilobites (Phillipsia, etc.) are probably to be correlated 

 with the Osage Series of the Middle Mississippian. Judged 

 by its plant remains the Burindi Series is probably not far 

 removed from the horizon of the Burdiehouse Limestone 

 of Scotland. It represents the Visean of Belgium, France 

 and Russia. The Burindi Series is perhaps homotaxial 

 with the Lipak Series of Spiti in the Himalayas. 



In Australia the Burindi Series of New South Wales may 

 be correlated with the coral limestones of Lion Creek, 

 Stan well, near Rockhampton in Queensland. 1
