this region, a short review of the work done on the Foraminifera will 

 not be out of place. 



Ehrenberg had material from many parts of the world, and some 

 of his samples included specimens from this area. Carpenter's work 

 really gives an idea of certain of the Philippine forms. He mentions 

 several species as occurring here, and notes that they vary more or less 

 from what he terms the same species from the Mediterranean. Defi- 

 nite data are not given, and the few species noted as occurring in the 

 region are not given further attention in this work, as they are for the 

 most part the larger and more common shallow-water species of the 

 tropical coral-reef fauna. 



It is in Brady's Report on the Challenger Foraminifera that the 

 first real sketch of the foraminiferal fauna of the North Pacific is 

 given, especially that of the deeper portions of the adjacent seas. A 

 considerable number of species and varieties are recorded from this 

 area, but the great majority of these are from three regions, really 

 from three stations. In point of view of richness, these are, first, 

 the coral reefs of the Hawaiian Islands, at a depth of 40 fathoms; 

 next a station off Japan on the Hyalonema ground, in 345 fath- 

 oms; the third station is just west of the Philippines, in 95 fathoms. 

 These three stations together furnished a large part of the North Pa- 

 cific records of the Challenger Report. Many of the other stations 

 gave but a few species; some none at all. From these facts it might 

 be imagined that the rich fauna of this area is in the shallow water, 

 and this has proved to be the case. As a rule, the globigerina ooze 

 away from the oceanic islands is uninteresting, consisting almost 

 exclusively of the pelagic types of Globigerina, Pulvinulina, Sphse- 

 roidina, etc. Near the islands it contains more species, but on the 

 whole is far less interesting than the somewhat similar ooze of the 

 North Atlantic. 



In 1893 Picaglia a recorded twelve species from three stations in 

 the mid-Pacific from the dredgings of the Vettor Pisani. Of these 

 two were additions to the Challenger, list. 



In 1894 Schlumberger b recorded a number of species from a single 

 station in the Sea of Okhotsk. Some of these were described for the 

 first time. He noted the meagemess of the fauna of this particular 

 portion of that ocean area, and his remarks have been confirmed by 

 my examination of the Albatross material of 1906 from the same 

 region. 



In 1896 Goes reported upon the Foraminifera from the region be- 

 tween the Galapagos Islands and the coasts of Mexico and Central 

 America. The area covered was fairly represented in the material
