has ever been demonstrated in the Permo-Carboniferous rocks of 

 that continent. Northern types have, however, long been known 

 to occur in Australia in Pre-Oarboniferous times. ^ The remarkable 

 absence of such association has recently been called into question. 

 In discussing a paper on some Australian plants, which I laid 

 before the Geological Society recently, Professor Boyd Dawkins - 

 stated that he had himself observed the association of Glossopteris 

 and Lepidodendron in New South Wales. On inquiry, I found that 

 Professor Boyd Dawkins had no specimens to bring forward in 

 support of his assertion, but he kindly gave me particulars of 

 the locality in which he stated such association occurred, with 

 full liberty to make use of the information. The horizon in 

 question was the kerosene shale beds about six miles from Hartley, 

 on the railway between that place and Lithgow, and to the west 

 of Wallerawang. Inquiry was kindly made into this matter for 

 me by Mr. Dun, of the Geological Survey of New South Wales. 

 He writes that such an association is at present quite unknown 

 in this or other districts of Australia. The Geological Survey 

 have just completed the survey of the Lithgow -Wallerawang 

 district, and have collected many hundreds of plant-remains from 

 these rocks, without a trace of a Lepidodendron or other northern 

 type. Neither the Survey, nor the Australian (Sydney) Museum 

 collections, contain any specimens showing such an association of 

 northern and southern forms, as Professor Dawkins stated occurred 

 in the rocks of New South Wales. 



The remarkable absence of northern types from the Permo- 

 Carboniferous rocks of Australia, and especially the absence of 

 representatives of the group Lycopodiales, would tend to show 

 that Australia was at that time far removed from land connections 

 with the northern continent. It is possible that an association of 

 Glossopteris and some Lycopod, such as Lepidodendron or Sigillaria, 

 may eventually be discovered in that continent, but for the present 

 there is no evidence that any such association occurs there.

IV. — The Pyrenees at the last Geological Congress. 

 By P. W. Stuart- Menteath, A.R.S.M. 



N recently completing, in the valley of St. Girons, and with the 

 cordial assistance of M. Caralp, a pedestrian exploration of 

 the Pyrenees, of which the first results appeared in the Bull. Soc. 

 Bamond of 1866, it occurred to me that my view of the recently 

 published Gompte Rendu and the Livret Guide of the Geological 

 Congress might be useful to foreign geologists. 



Two Pyrenean excursions are described. That conducted by 

 M. Lacroix is an example of the application of microscopic study 

 in Paris to the confirmation of the observations of the colleagues 

 of their author. He admits, in the recently published Compte Rendu, 

 that these results are mistaken in regard to the age of both granite
