For the sake of brevity, many of the references to Journals 

 have been abbreviated, as for example: Contributions from the 

 Cushman Laboratory for Foraminiferal Research (Contr. 

 C. L. F. R.) ; Bulletin American Association of Petroleum Geol- 

 ogists (Bull. A, A, P. G.) ; United States National Museum 

 (U. S. N. M.) ; United States Geological Survey (U. S. G. S.) ; 

 etc. 



While many papers dealing v^ith other than systematic descrip- 

 tion or ranges are left out of this bibliography the reader is re- 

 ferred for papers in regard to methods, etc., to the paper with 

 its bibliography by R. D. Reed, "Microscopic Subsurface Work in 

 Oil Fields of the United States" (Bull. A. A. P. G., vol. 15, 1931, 

 pp. 731-754). 



While the mimeographed "Micropaleontology Bulletin" of 

 Stanford University is not a publication in the strict sense, it is 

 nevertheless available to many workers, and as it includes valu- 

 able records, it is included here. 



Most of the new literature on the Foraminifera is recorded 

 quarterly in the Contributions from this Laboratory, so that with 

 the present bibliography it is possible for the worker to keep in 

 contact with the literature on American Foraminifera. 



Cushman Laboratory for Foraminiferal Research,
