FORAMINIFE'RA of north pacific ocean. 41 



north of Guam. It' also occurred at three other Nero stations; 1439 

 in 1,901 fathoms also north of Guam; 1691 in 1,912 fathoms be- 

 tween Guam and the Midway Islands, and 166 in 1,850 fathoms 

 between the Midway and Hawaiian Islands. 



This variety is characterized by very fine, often slightly wavy 

 longitudinal striae, a type of ornamentation which seems to go with 

 the broad keel with fine tubulations.

 CI. ii, vol. 18, 1893, p. 335, pi. 10, fig. 85. 



Description. — Test flask-shaped, compressed, body of test elongate 

 oval, with a long, tapering, slender neck, the central portion of the 

 test immediately surrounded on either side by a raised edge outside of 

 which peripherally is a broad keel with radiating fine tubulations; 

 apertural and apical ends of the central portion of the test passing 

 into the inner keel by a series of interrupted costse, apical end of 

 peripheral keel usually emarginate. 



Length up to 1 mm. or more. 



Distribution. — Brady records this species from two CTiaUenger sta- 

 tions in the North Pacific, in 1,850 and 2,575 fathoms. Goes records 

 it from Albatross station 3399 in the eastern Pacific in 1,740 fathoms. 

 I have found this species to be fairly common in the Nero material 

 from the region between Guam and Yokohama, mostly in compara- 

 tively deep water, the depths varying from 1,417 to 2,119 fathoms. 

 It occurred near Guam at Nero station 1464 in 891 fathoms; near the 

 Midway Islands, Nero station 170 in 1,990 fathoms; station 91 in 

 1,983 fathoms and off the Hawaiian Islands, Nero station 10 in 2,098 

 fathoms. 



This is a large and beautifully ornamented species. It seems to be 

 widely distributed in deep water.

Lagena formosa Schwager, var. favosa H. B. Brady, Rep. Voy. Challenger, 

 Zoology, vol. 9, 1884, p. 480, pi. 60, fig. 21. 



Description. — Variety differing from the typical in having two or 

 three rows of reticulate ornamentation between the body of the test 

 and the peripheral wing. 



Length 1 mm.
