rOEAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS.

Owing to the weakness of the stolonlike connections between the 

 chambers it is rare for more than two or three chambers to be found 

 connected in dredged material. In the North Pacific material spec- 

 imens were found which appeared to have the proloculum intact 

 but the Challenger material showed none with the proloculum pres- 

 ent. Single chambers with the stolonlike tubes are the most com- 

 mon condition.

Specimens here referred to this species have been found at but 

 four stations in the region, at one of which the specimens were in 

 some numbers. The data for these stations show that its occur- 

 rence agrees with the rest of the Pacific records as to its being found 

 at a considerable depth. The stations were: D5178, off Romblon, 

 73 fathoms (133 meters); D5460, east coast Luzon, 565 fathoms 

 (1,074 meters); D5639, Molucca Sea, 1,560 fathoms (2,853 meters), 

 bottom temperatures not given; and D5668, Macassar Strait, 901 

 fathoms (1,648 meters), bottom temperature 38.2° F. (3.4° C). 



An examiuation of Valorous material and other North Atlantic 

 specimens has seemed to show that the typical R. hacillaris has a 

 very definite distribution in the North Atlantic; also the size, form, 

 and number of chambers, color, and in general the whole character 

 of the species is very definite. The Philippine specimens are not 

 typical, and it is probable that they do not represent this species. 

 The discussion of the species is given in Bulletin 104, part 2, page 18.
