raised costae, the furrows between divided transversely by less well- 

 developed transverse costae. 



Length 0.25 mm. 



Distribution. — Specimens occurred at three Nero stations between 

 Guam and Yokohama; 1065 in 1,321 fathoms, 1128 in 1,418 fathoms, 

 and 1301 in 1,088 fathoms. The coarser of these is here figured. 

 The other is much finer in its sculpturing. Both specimens are closer 

 to Reuss's figure than those given by either Millett or Sidebottom.

Lagena foveolata Reuss (?), var. paradoxa Sidebottom, Journ. Quekett Micr. 

 Club, vol. 11, 1912, p. 395, pi. 16, figs. 22, 23. 



Description. — Test flask-shaped, elongate, broad and rounded at 

 the aboral end, tapering gradually toward the apertural end; neck 

 short but definite; wall ornamented with longitudinal costse running 

 the entire length of the test, the inner costal furrows divided trans- 

 versely by slightly raised lines and the whole furrow occupied by a 

 double row of elongate, fine openings, outer wall tending to disinte- 

 grate and flake off, leaving the inner wall of the test exposed and 

 spinose, the spines in longitudinal lines. 



Length of North Pacific specimens 1 .25 mm. 



Distribution. — This variety was described from the southwest 

 Pacific. This characteristic ornamentation and disintegration of 

 the test is apparent in material from Nero station 2052 in 1,184 fath- 

 oms off the Hawaiian Islands.

332, pi. 6, figs. 74, 75. 



Description. — Test pyriform, nearly circular in transverse section 

 or polygonal, surface ornamented with prominent longitudinal costae, 

 with a series of coordinate transverse costae between, usually hori- 

 zontal or slightly arched upward. 



Length about 0.25 mm. 



Distribution. — This species occurred at the following North Pacific 

 stations: Nero, 1129 in 1,505 fathoms, and 1310 in 518 fathoms, 

 between Guam and Yokohama; also at Albatross station, D4843 in 

 100 fathoms off Japan. 



Although the original figure given by Williamson shows a surface 

 ornamentation less regular in character than those figured here,
