FORAMINIFERA OF NORTH PACIFIC OCEAN. 13 



both as to depth and bottom conditions. A considerable number of 

 new species was discovered, and from the list of species given much 

 can be made out as to the characters of the fauna. Goes returned to 

 the National Museum a set of nearly all the species he recorded, and 

 his selected material has been carefully studied in connection with 

 the present work. 



In 1899 Flint's report on the Albatross Foraminifera a added to 

 the previous knowledge by records from scattered stations on the 

 west coast of North America and a few species from the western 

 Pacific. Most of the stations from which the material was taken for 

 his report were in the North Atlantic. His report on the Nero mate- 

 rial b added a few records to the previous ones, although in that 

 report as a rule only the genera were mentioned, the work dealing 

 with oceanography rather than determination of the species in the 

 deposits. Something of the general character of the fauna of various 

 areas may be ascertained from the genera mentioned. 



In 1906 Rhumbler reported upon material from Laysan and the 

 Chatham Islands. The material came from shallow water. Of the 

 species recorded a considerable number were described as new. 

 These records are especially interesting as they represent the littoral 

 fauna not previously recorded, except from the Hawaiian Islands in 

 the Challenger Report. Rhumbler's records show the existence of a 

 shallow-water fauna of tropical character about these islands, and the 

 new species indicate the individuality of these more or less isolated 

 areas. 



In 1908 Bagg d recorded a considerable number of species from the 

 immediate vicinity of the Hawaiian Islands. These records add con- 

 siderably to the recorded fauna of the shallower water as given in the 

 Challenger Report. In this Albatross material the stations reported 

 upon were mainly in globigerina ooze and for the most part lack the 

 shallower water species so common on the coral reefs of this region. 

 The series selected by Doctor Bagg has been examined and the results 

 of this examination appear as the species are discussed. 



Altogether the eight titles mentioned have built up a rather numer- 

 ous fauna for the North Pacific, but the material that was available 

 for all of them was rather meager when compared with the material 

 available for the present work. As a result, not only has a very large 

 proportion of the previously recorded species been rediscovered, but 

 a great many species have been added, some new, and some pre- 

 viously described from other areas. The large series of specimens 

 has added greatly to the ranges of distribution for species which were
