FOKAMINIFERA OF NORTH PACIFIC OCEAN". 43 



Distribution. — Goes records the elongate form of this species from 

 Albatross stations in the eastern Pacific in 1,132 to 1,201 fathoms. 

 I have had specimens from Nero station 2049 in 2,226 fathoms off 

 the Hawaiian Islands and from numerous stations between Guam 

 and Yokohama, depths ranging from 688 to 1,907 fathoms. It also 

 occurred at two Albatross stations off Japan, D4957 in 437 fathoms 

 and D4975 in 712 fathoms. 



The elongate form here figured has occurred much more frequently 

 than the rounded form.

Description. — Variety with the body portion of the test marked by 

 a network of lacunae or pitted areas of varying size, usually darker in 

 color than the rest of the test. 



Length 0.35 mm. 



Distribution. — Brady records this variety from the Challenger 

 station south of Japan on the Hyalonema-ground, depth 345 fathoms. 

 I have had material from three Nero stations between Guam and Yo- 

 kohama, 1154 in 1,602 fathoms, 1300 in 1,529 fathoms, and 1310 in 

 518 fathoms. It also occurred at two Albatross stations off Japan, 

 D4875 in 59 fathoms and D4966 in 290 fathoms, and at Tuscarora 

 station 23, lat. 21° 40' N.; long. 179° 20' E., in 1,964 fathoms. 



Schwager's figure and description call for a specimen with its orna- 

 mentation made up of raised beads on the body portion of the test. 

 It seems that a distinction should be made between the raised beads 

 and pitlike lacunae.
