disjuncta bed. This imperfectly preserved and undescribed fossil 

 plant is among the specimens exhibited to-night. 



These discoveries do not disprove, therefore, any conclusions 

 previously arrived at as to the age of Lepidodendron in Australia, 

 but should help to carry the inquiry a stage further back into the 

 past history of the world's plants. The obvious inference is either 

 that some variety o^ Lepidodendron in Australia descends into the 

 Upper Devonian, or that Sjnrifera disjuncta ascends into the 

 Lower Carboniferous. 



The fact might be mentioned here that Mr. William Anderson, 

 Government Geological Surveyor, and Mr. P. T. Hammond, 

 Geological Field Assistant, have lately discovered Lejndodendron 

 australe at a new locality at Back Creek, near Major's Creek, in 

 New South Wales, associated with a marine fauna of Upper 

 Devonian or Lower Carboniferous affinities. The results of their 

 explorations in this district, when elaborated, should therefore 

 form an important contribution to our knowledge of the geological 

 range of Lepidodendron australe in New South Wales.
