charge of different periods for the addition or 

 completion of data, and annotations and geo- 

 logical sections as outlined in the preliminary 

 bulletins. With similar data from foreign 

 horizons these will form a broader and more 

 permanent basis for exact correlation than has 

 hitherto been available. 



The general interest that has recently been 

 aroused among students of fossil vertebrata 

 is attested by the appearance of a number of 

 important papers dealing with the more exact 

 correlation of formations in which fossil 

 vertebrates are found. Important additions to 

 the evidence as to the position of the Mesozoic 

 and Csenozoic formations of the Argentine by 

 Ameghino, Eoth, Scott, Ortmann, Hatcher 

 and Sinclair have in recent years advanced 

 this diiEcult problem a long way toward solu- 

 tion. The recent work of J. C. Merriam in 

 California, Oregon and Nevada has been of 

 the highest quality and great importance in 

 correlation of the Pacific slope and other sec- 

 tions of this continent. Von Huene's investi- 

 gations in the European Triassie, Broom's 

 studies upon the South African Permian and 

 Mesozoic, have already gone far toward clear- 

 ing up these great problems in correlation. 

 These are cited but as examples of the spirit 

 of thorough, exact and progressive method in 

 which many investigators are carrying on the 

 work, each in his special province. 



Correlation of more or less importance is 

 contained in the series of papers published 

 within the last year by Osborn, Matthew, 

 Douglass, von Huene, Knowlton and Broom. 



During the coming year the secretary of the 

 committee will devote himself to the prepara- 

 tion of correlation lists for the North Ameri- 

 can Tertiary and for the North American 

 pre-Tertiary. Data will be prepared for the 

 North American Cretaceous and Cretaceous- 

 Eocene contact by Osborn and Brown. The 

 committee has promised also a number of 

 American and foreign pre-Tertiary f aunal cor- 

 relations by members and associates. 



Inquiries should be addressed to W. D. 

 Matthew, American Museum of Natural His- 

 tory, New York.
