The primary object of the present communication is to suggest a correlation of the Lower Limestone group between Renfrewshire and Ayrshire. The sediments of these two areas are no longer in direct continuity: whatever may have been the case in the pa

The present paper is based on the study of a suite of fossils collected in 1898 by Dr W. S. Bruce, during a cruise with Major Andrew Coats in the Barents Sea, on board the yacht Blencathra.The fossils were found in situ in a cliff at the extremity of

Amongst the Carboniferous corals, not the least interesting are those species which, for one reason or another, may be difficult to classify, or at any rate diverge somewhat from the common order. It is with one of these aberrant members that the pre

( Presidential Address, November, 1943). The Glacial Drifts of northern Britain are known to us all but too well. We cannot escape them; their clays, their sands and gravels confront us at every turn, so masking the underlying rock that they are a po

Of late years it has become increasingly evident that a serious effort ought to be made to clear up the doubts and uncertainties attending Lower Carboniferous correlations in the North-Eastern Pennines. The Geological Survey maps, always the main sou

Three years ago when I was discussing certain Carboniferous Corals from Arctic regions the opinion was expressed that the genus Lophophyllum of Milne-Edwards & Haime had been erroneously interpreted by palæontologists, and that in reality it include

The subject of this communication has already been brought before the Society by Mr. James Neilson.* Still, even when considered from a purely zonal standpoint, Carboniferous palaeontology is inevitably associated with so many side issues that a furt

There are several constants of value in the determination of this species. They are:—(1) The epithecal characters; (2) the spacing of the major septa (i.e. their number in a given diameter); (3) the thickening of stereoplasma in the lower and conic
