vaughan: correlation of tertiary formations 269 



tioned are not likely to be distributed within less than twelve 

 months and as there is considerable demand among geologists 

 for the stratigraphic results contained in them, it is desirable at 

 least to publish promptly the tabular summaries. 



Tables such as those here given are necessarily based on the 

 work of many men, and I wish to express my indebtedness to 



E. W. Berry, J. E. Brantly, C. W. Cooke, J. A. Cushman, W. H. 

 Dall, .\lexander Deussen, E. T. Dumble, E. N. Lowe, W. C. 

 Mansfield, G. C. Matson, G. S. Rogers, E. H. Sellards, E. W. 

 Shaw, H. K. Shearer, and L, W. Stephenson, who have con- 

 tributed to the literature on the Tertiary formations of the 

 southeastern and southern United States during the past six 

 years. I have also had the benefit of the unpublished results of 



F. Canu and R. S. Bassler on the Tertiary Bryozoa of the Coastal 

 Plain of the United States and of Miss Julia Gardner on the 

 Mollusca of the upper Miocene of Virginia and North Carolina 

 and of the lower Miocene (the Alum Bluff formation and its 

 members) of Florida. More specific referrences to the con- 

 tributions of these investigators -will not be made in this place. 



Recently the Director of the U. S. Geological Survey, in fulfil- 

 ment of a cooperative agreement between the Geological Survey, 

 the Canal Commission, and the Smithsonian Institution, trans- 

 mitted to the Secretary of the Smithsonian Institution the manu- 

 script and illustrations for a volume entitled Contributions to the 

 Geology and Paleontology of the Canal Zone, Panama, and Geolog- 

 ically Related Areas in Central America and the West Indies. Pre- 

 pared under the direction of T. W. Vaughan. This volume contains 

 the following papers: Preface, by T. W. Vaughan; On Some 

 Fossil and Recent Lithonamnicae of the Panama Canal Zone, by 

 M. A. Howe; The Fossil Higher Plants from the Canal Zone, 

 by E. W. Berry; The Smaller Fossil Foraminifera of the Panama 

 Canal Zone, by J. A. Cushman; The Larger Fossil Foraminifera 

 of the Panama Canal, by J. A. Cushman; Fossil Echini of the 

 Panama Canal Zone and Costa Rica, by R. T. Jackson; Fossil 

 Bryozoa from the Canal Zone and Costa Rica, by F. Canu and 

 R. S. Bassler; Crustacea Decapoda from the Panamanian Re- 

 gion, by M. J, Rathbun; Cirripedia from the Panama Canal
