FORAMINIFERA OF NORTH PACIFIC OCEAN. 107 



comparatively large pitted depressions or perforations; aperture 

 circular with a very short neck and flaring lip. 



Length 0.5 to 0.8 mm. 



Distribution. — Bagg records this species from three Albatross 

 stations in the vicinity of the Hawaiian Islands, in 572 to 1,259 

 fathoms. In the same region it occurs at Albatross station H3007 

 in 323 fathoms. In the western Pacific it has occurred off the 

 coast of Japan, Albatross station D4957 in 437 fathoms. It also 

 occurred at Nero stations 1306 and 1311 in 1,20S and 1,503 fathoms 

 and at two Tuscarora stations 47 and 58 in 1,499 and 814 fathoms. 

 These last four stations are not far from the Bonin Islands. At D4957 

 the bottom temperature was 39.8°, but it is not recorded from the 

 other stations. 



This s'pecies is more widely distributed than others of the genus, 

 both in depth and area. It is characteristic in its appearance and 

 can easily be distinguished. 



Goes * refers to this species a form which is evidently a Clavulina, 

 as his figures and description show. Later he figured a specimen 

 in his work on the Scandinavian Foraminif era 2 which very clearly 

 belongs to this species. 



The interior has the characteristic tubular structure as shown in

Description. — Test elongate, cylindrical, chambers of the uniserial 

 portion broader than long, sutures not deep but conspicuous, wall 

 ornamented by longitudinal costae, not close together and not high; 

 aperture circular with no neck but a prominent rounded lip. 



Length 0.75 to 1 mm. 



Distribution. — Brady records this species at one North Pacific sta- 

 tion off the Philippines in 95 fathoms. I have found specimens from 

 the vicinity of the Hawaiian Islands, Nero station 2035, in 1 14 fathoms, 

 Nero Station 1466, off Guam, 234 fathoms, and a specimen which can 

 be referred here from Nero station 1321, southeast of the Bonin 

 Islands in 1,618 fathoms.
