BULLETIN 161, UNITED STATES NATIONAL MUSEUM 



Most of the papers published on the foraminifera of the Indo- 

 Pacific region are cited in the synonymy under the various species, 

 and in some of them species were figured and described that were 

 not obtained in our collections. To have added all the other records 

 from the general Indo-Pacific region would not only have greatly 

 enlarged this work, but would have involved the addition of many 

 species the types of which were not available for study. It has 

 seemed best, therefore, to limit the scope of the work to the actual 

 collections of the Albatross and to the other available shallow- water 

 deposits from the same groups of islands. 



Though the fauna as a whole is a unified one, nevertheless the 

 study of the present collections shows that there are in the shallow 

 water about various groups of oceanic islands of the South Pacific 

 locally developed species that are strictly limited. The species of 

 deeper water, however, have a wide distribution. 



Furthermore, there are numerous species that occur definitely asso- 

 ciated in other areas. For instance, many are widely distributed 

 among the islands of the South Pacific that are known also from the 

 West Indian region. Others are known from the Mediterranean and 

 the Red Sea regions. A few of them are very closely related to 

 species originally described from the warm-water facies of the 

 Miocene or Pliocene of southern Europe. 



The accompanying map (fig. 1) shows the general path of the 

 Albatross during this voyage, and for further details the reader is 

 referred to the tables accompanying a number of the species. These 

 give the depth, temperature, and other data regarding the samples 

 from which the material was taken. 



The plates are all from original drawings made from the collec- 

 tions by Miss Margaret S. Moore, and form perhaps the most useful 

 part of the present work. 



I wish to take this opportunity to express my great appreciation 

 of the many kindnesses and the constant help that the United States 

 National Museum and its staff have so constantly given me in the 

 study of this and other material.
