Lower Carboniferous Zones. — Faunal Correlation of the Dinaniian of 

 Belgium with the Avonian of Britain. 



I was able, in the summer of 1909, to study the most important 

 sequences in the Lower Carboniferous of Belgium ; the subjoined corre- 

 lation is the result of observations then made. 



My thanks are most gratefully tendered to those who so ungrudgingly 

 devoted their time to my assistance; to Mr. G. Delepine, of the 

 Catholic University of Lille, who planned the itinerary and accompanied 

 me throughout my visit; to Mr. A. Carpentier, of the same University, 

 who conducted me over the Avesnes district of N.E. France; to Dr. 

 F. Kaisin, of the University of Louvain, for his guidance in the Dinant 

 district; to Mr. P. Destinez, of the University of Liege, for help at 

 Vise and in the study of his collection; to Dom. P. Beda for help at 

 Maredsous and in the abbey collection ; and to Prof. H. Dorlodot for the 

 gift of papers and books. 



In the matter of stratigraphical terms and indices I have, neces- 

 sarily, adhered to the official publication, ' Legende de la Carte 

 geologique de -la Belgique (1900),' only introducing the notation of 

 Dorlodot for two new terms, Tld and T2c. 



For the most recent and authoritative account of the Belgian rocks 

 and of their stratigraphical relations reference has been made to two 

 mutally supplementary papers by Prof. Doxiodot, entitled ' Les Faunes 

 du Dinantien et leur signification stratigraphique, ' 1 and ' Description
