beds of that age in Tasmania, notably Brown's River, Black- 

 mans' Bay Heads (East Coast), Blackmans' Bay (near Brown's 

 River), One Tree Point, North Bruny, and Lindisfarne. In the 

 Derwent, notably overlying the basalts at Lindisfarne, similar 

 conglomerates occur in lenticular patches among sandstones. 

 The most of the harder materials in these- sandstone con- 

 glomerates have been derived by disintegration and redistribu- 

 tion of the older glacial erratics of the adjacent Permo-Car- 

 boniferous rocks. He therefore inclined to the idea that the 

 reconciliation of apparently confjlicting evidences at Table Cape- 

 was to be found in accepting the hypothesis that two distinct 

 conglomerate formations containing glacial erratics occur at this 

 place. The older conglomerate is undoubtedly of Permo-Car- 

 bonifcrous age, the later conglomerate deriving the most of its 

 harder materials from the disintegration of the older glacial 

 conglomerates either at the earlier stages of the formation of 

 the Tertiar}^ Marine beds (Palaeogene), or towards its close. 

 Further evidence will be necessary before this last point can be 

 settled satisfactorily.

THE FOLLOWIKG PAPERS WHKE READ; 



(i) Geological Notes on the country traversed by the Der- 

 went Valley Railway Extension. By T. Stephens, M,A., F.G.S. 



The paper gives a general description of the basaltic sheet 

 once extending continuously from Macquarie Plains to Glenora, 

 and the occurrence in it of one of the new railway cuttings of 

 masses of opal with traces of fossil wood. The intensely hard 

 and brittle character of the neighbouring diabase is noted, and 

 the evidence of its existence as an intrusive sill, or laccolite, 

 under the sandstone formation illustrated by a Plate. The pre- 

 sence of numerous erratics in the neighbourhood and along the 

 course of the new railway is mentioned, as affording evidence 

 of glacial action in not very remote times. 



Dr. Noetling said that he had long suspected glacial action 

 in the Derwent Valley, and was glad to hear that such circum- 

 stantial evidence of it had been discovered. 



Mr. Piesse remarked that other mountain ranges in Eastern 

 Tasmania, instancing Ben Lomond and its outliers, showed un- 

 mistakable evidence of glaciation, and hoped that the matter 

 would be more fully investigated. 



(2) Points in the Morphology and AnattMuy of certain ]\Iega- 

 podes. By T, Thomson Flynn, B.Sc, 



The author describes the results of his examination of speci- 

 mens of two genera represented by the Scrub Turkey and the 

 Mallee Fowl, and treats separately of the Pterylosis, or feather 

 arrangement, and the Myology of the hind limb. The paper is 

 illustrated by descriptive figures.
