THE CARBONIFEROUS CORALS OF THE CLYDE 



DRAINAGE AREA. 



BY (THE LATE) JAMES THOMSON, F.G.S. 



THIS list of the Carboniferous Corals of the Clyde drainage area was drawn 

 up by Mr. Thomson only shortly before his death in 1899, and therefore has 

 not had the benefit of his revision in print. So far as possible it has been 

 compared with an exhaustive paper on the Scottish Carboniferous Corals, 

 which Mr. Thomson read before the Philosophical Society of Glasgow in 

 1883, and which was published at length in its Transactions, accompanied by 

 14 plates with numerous figures. 1
