PREFACE. 



ON the establishment of the Geological Survey of Nigeria in 1919, it was 

 found that there existed a considerable amount of unpublished information 

 about the geology of the Southern Provinces. Steps were accordingly taken 

 to collect this material and arrange it for publication. Mr. R. Bullen Newton, 

 I.S.O., of the British Museum, kindly undertook the description of the 

 collections of fossil shells from Ameki on the Eastern Railway which had 

 been presented to the Museum at various times by Sir Frederick Lugard, 

 Sir John Eaglesome, and Mr. A. E. Kitson. Mr. Newton secured the co- 

 operation of Mr. E. Heron-Allen, F.R.S., and Mr. A. Earland, F.R.M.S., 

 and the reports of these distinguished authorities which appear in this 

 Bulletin form a most valuable contribution to the Tertiary Geology of 

 Africa.
