FORAMINIFERA OF NORTH PACIFIC OCEAN. 



43 



perforate; aperture terminal, in end view nearly central, long-oval, 

 slightly constricted near the middle, bordered by a rounded raised 

 lip; color, white or gray. 



Length about 0.75 mm. 



Distribution. — In the North Pacific, Brady records this species 

 from ChaMenger station 209, in 95 fathoms, off the Philippines. I 

 have seen specimens from two Albatross stations, D4875, in 59 

 fathoms, eastern channel of Korea Strait, and 

 D4964,in 37 fathoms, off the southern coast 

 of Japan. Brady also records the species 

 from off the north coast of New Guinea, 

 1,070 fathoms, and in Torres Strait, in 155 

 fathoms. 



The specimens I have had for study are of 

 the same form and with the same details as 

 those figured by Brady. The specimen fig- 

 ured by Egger° does not seem to be of this 

 species and is referred elsewhere 



BOLIVINA PLICATA d'Orbigny. 



Bolivina plicata d'Okbigny, Voyage Amer. Merid., 

 vol. 5. pt. 5, "Foraminiferes," 1839, p. 62, pi. 8, 

 figs. 4-7.— Bagg, Proc. U. S. Nat. Mus., vol. 34, 

 1908, p. 138. 



This species is recorded by Goes from Alba- 

 tross station D3395, in 730 fathoms, but an 

 examination of the selected material mounted 

 by Goes from this station shows it to be a 

 new species, later described. 



Bagg records B. plicata from a single station 

 near the Hawaiian Islands, but his mounted 

 specimen is unfortunately difficult to study, 

 and dismounting was not attempted. 



I have found no material in the North 

 Pacific referable to this species.

BOLIVINA SEMICOSTATA, new name. 



Bolivina costata H. B. Brady, Rep. Voy. ( 'Mllenger, Zoology, vol. 9, 1884, p. 426, 

 pi. 53, figs. 26, 27 (not B. costata d'Orbigny, 1839). 



Description. — Test broadly oval, two-thirds as broad as long, the ends 

 obtusely rounded, somewhat compressed; chambers few, the sutures 

 distinct, somewhat depressed; wall calcareous, ornamented with a 

 number of raised rounded costse running lengthwise of the test,
