DRAINAGE AREA. 



BY J. G. GOODCHILD, F.G.S. 



THE following list of the Carboniferous Gasteropoda occurring in the Basin 

 of the Clyde has been compiled from various sources, chiefly by Mr. A. 

 Macconochie, Assistant Curator of the Scottish Geological Survey Collections. 

 The nomenclature of this section of the mollusca remains in a very un- 

 satisfactory state, except as regards the species which have been revised by 

 Miss Donald.
