A BIBLIOGRAPHY OF AMERICAN FORAMINIFERA 

 By Joseph Augustine Cushman 



The intensive work now being done on the Foraminifera in 

 America and the increasing amount of new literature appearing 

 in scattered journals is the basis for the present bibliography. 



Primarily the object is to give to the worker on the Foramin- 

 ifera reference to those papers which deal with American genera 

 and species. Papers by American authors which are of a general 

 nature and have no bearing on the faunas are not included. 

 Also papers of a purely geological nature are usually left out 

 unless they have included authentic names of foraminifera with 

 localities or ranges. Numerous earlier works of an historic in- 

 terest as giving the first records of foraminifera from a particu- 

 lar region are included. These appear in the form in which they 

 appeared in Sherborn's excellent Bibliography so that no con- 

 fusion may result in comparing the titles. 



In order to be of more use to the specialist, one or more letters 

 in bold type will be found at the end of each title, R=Recent; 

 T=Tertiary; C=Cretaceous ; and P=Palaeozoic. These letters 

 indicate the main scope of the paper. In some cases a single let- 

 ter will be found where the paper covers more than one of these 

 groups, but that one refers to the Afnerican records only. 



The mainlands of North and South America together with the 

 islands usually associated with them are included here, as well as 

 the Recent records from the adjacent coasts, but not the purely 

 oceanic areas of the Atlantic and Pacific. It is probable that 

 scattered records have been overlooked. 



The bibliographies of Sherborn, Brady, Woodward, Winter, 

 Toutkowsky, Beutler and Liebus have been freely used, but the 

 main source of information has been the library of this Labora- 

 tory where most of the original works are available.
