FOEAMINIFEKA OF NORTH PACIFIC OCEAN. 71 



Desertion. — Test elongate, compressed, early chambers close 

 coiled, later ones becoming uncoiled, elongate; sutures slightly de- 

 pressed; wall smooth; periphery rounded, without a keel. 



Length up to 3 mm. 



Distribution. — Brady records this species from 40 fathoms off the 

 coral reefs of Honolulu, Hawaiian Islands, and in the Challenger 

 volume on "Summary of Results," it is also recorded from Challenger 

 station 246 in 2,050 fathoms. Goes records it from two Albatross 

 stations, D3375 and D3376, in 1,201 and 1,132 fathoms, respectively, 

 in the eastern Pacific. Bagg records it at four Albatross stations in 

 the vicinity of the Hawaiian Islands; D4000 in 104-213 fathoms; 

 H4430 in 1,544 fathoms; H4508 in 495 fathoms; and H4694 in 865 

 fathoms. 



I have had specimens from numerous Nero stations about the 

 Hawaiian Islands, west of Midway Island, and between Guam and 

 Japan, ranging in depth from 518 to 2,080 fathoms. Off the Gala- 

 pagos I have had it from D2806 in 1,379 fathoms, and off Japan at 

 the following stations: D4949 in 110 fathoms, bottom temperature 

 57.8° F.; D4966 in 290 fathoms, bottom temperature 44.1° F.; and 

 D4967 in 244 fathoms, bottom temperature 45.9° F.

pi. 67, fig. 18a, 6. 



Description. — Test broad, subtriangular in side view, much com- 

 pressed, early chambers somewhat close coiled, later ones very 

 elongate and uncoiling, sutures very slightly depressed, oblique, wall 

 smooth, aperture somewhat produced, radiate. 



Length up to 2 mm. 



Distribution. — This species has been previously unrecorded from 

 the North Pacific. I have had specimens from the three following 

 stations, Albatross D4843, in 100 fathoms, bottom temperature 39.9° 

 F., off Japan, and Tuscarora 11, in 437 fathoms, lat. 33° 46' N.; 

 long. 140° 21' E. and Tuscarora 126, in 500 fathoms, lat. 54° 08' N.J 

 long. 161° 31' W. 



This species seems to be a broadened development of a form like 

 C. crepidula, but seems to have characters which make it distinct 

 from that species.
