sary. The classification adopted is that already used in an earlier 

 series of papers * and in the earl}' parts of another paper now being 

 issued.^ In these papers will be found more detailed synonymy and 

 the discussion of the classification and changes of name which have 

 occurred in the earlier work. References to these papers and to the 

 OhaUenger Report are given for nearly all the older species. The 

 descriptions of many of the new species have already beer pub- 

 lished and references to the place of publication given, though for 

 ease of reference the descriptions have been given in full for the 

 species described as new from these collections. 



Figures have been given for most of the species and all have been 

 taken from material of this collection. Most of these are drawings, 

 but a few are photographs. Many more figures could well have 

 been used to illustrate the various species and varieties. It would 

 have been of interest to show the developmental stages of numerous 

 species, but this would have mvolved the drawing of many more 

 figures and a considerable increase in the number of plates. 



The work of completing the present report would have been impos- 

 sible but for the very kindly help which has been unstintingly given. 

 The Bureau of Fisheries under Conmiissioners George M, Bowers, 

 Dr. Hugh M. Smith, and Deputy Commissioner H. F. Moore, has 

 given unceasing aid in the furnishing of assistance in preparing the 

 material and the work of getting the manuscript and figures in shape. 

 The United States National Museum has taken care of the mounting 

 of the slides of material and help in other ways. That the material 

 is so rich is very largely due to careful work of Dr. Paul Bartsch 

 during the time he had charge of the collecting work of the Alhafross 

 in the Philippines. Miss Jennie F. Cushman is responsible for the 

 large series of species and specimens which are due to her pains- 

 taking work in patiently picking out the forammifera from the mass 

 of the bottom samples after they were carefully washed. A con- 

 siderable portion of the figures were drawn by Mr, Edward Oilman, 

 whose excellent work speaks for itself. Messrs. Charles B. Ames. 

 S. N. F. Sanford, and Miss Margaret Birch did much of the card cat- 

 aloging of records. Miss Jane M. Furber gave much time to the 

 preparmg of card records and the earlier part of the manuscript. 

 Especially to Miss Shirley P. Beck are my thanks due for her very 

 efficient and painstaking work in bringing together in systematic 

 shape the various parts of the work, preparing the tables of distri- 

 bution, and generally getting the manuscript into its final form. 

 Without her careful work it would have been hardly possible to have 

 gotten the whole into its final shape.
