species of cold waters in high latitudes. This goes to further prove 

 the wide distribution of these arenaceous forms in cold waters, tem- 

 perature instead of depth having the greater control in their distri- 

 bution. 



However, many of the species of these arenaceous foraminifera 

 were undescribed and their nearest allied species so far as present 

 distribution is known are far away. These include species of Hali- 

 physema, Dendroplirya. Bathysiphon, etc. They show what other 

 observers have found, especially Heron-Allen and Earland in their 

 work about the British Isles, that arenaceous species often occur in 

 great abundance in very restricted localities. Certain species of the 

 above genera at some of the stations made up a very large percent- 

 age of the foraminifera of the bottom material but were not found 

 elsewhere. 



One of the most interesting stations in the whole of the Albatross 

 dredgings is D5236, in 494 fathoms (903 meters), Pacific Ocean, 

 east coast of Mindanao. The bottom material is of a peculiar brown- 

 ish color and contains a ver}'^ unusual assemblage of species, a large 

 number of which have been described here as new. A large number 

 of rare species have also occurred at this station which have not been 

 found elsewhere in the region. A list of the species from this station 

 is given, as well as from other stations of exceptional interest to show 

 the general character of the foraminiferal fauna in some of the various 

 parts of the area. 



Globigerina-ooze is developed in some parts of the Sulu Sea and 

 in the southern area. This is rather typical in most of its species 

 but lacks certain ones. This probably may be due to currents 

 and will be mentioned w^here the Globigerinidae are discussed. 



One of the most interesting finds in the region is Nevillin^ coronata, 

 a very rare species and of especial interest from its relationship to 

 other Miliolidae. The great abundance of Cycloclijpeiis carpenteri 

 in certain parts of the area was an unexpected find. It is the largest 

 of the living calcareous foraminifera. 



In general the foraminiferal fauna of the Philippine area is that of 

 the Indo-Pacific, including the Hawaiian Islands on the east, the 

 South Sea Archipelagoes, and Australia to the southw^ard, and going 

 westw^ard to the East Coast of Africa, Madagascar, the Red Sea, and 

 in some cases, the Mediterranean. This is only in general, however, 

 and there are many characteristic species of the area which so far as 

 is now known are limited to this region. 



The systematic portion follows, giving the species with notes on 

 their distribution in the area.
