Description. — Test elongate, tapering, slightly curved, composed 

 of numerous chambers, short and cylindrical in form, sutures but 

 slightly depressed in the early portion, later chambers more tumid 

 and sutures somewhat depressed; wall smooth, apical and rounded. 



Length up to 8 mm. 



Distribution. — Bagg records this form from Albatross station D4000 

 in 104-213 fathoms off the Hawaiian Islands. I have had material 

 from the same region at Albatross station H2922 in 268 fathoms, 

 bottom temperature, 44.8° F.; H2986 in 271 fathoms; and Nero 

 station 2071 in 271 fathoms. It occurred at Nero station 1464 in 891 

 fathoms, off Guam; and Albatross stations H4882 in 248 fathoms, 

 off southern Japan, bottom temperature, 48.8° F., and D4965, also 

 off Japan, in 191 fathoms, bottom temperature, 49.4° F.

Description. — Test elongate, tapering, broadest near the apertural 

 end, composed of few chambers; wall smooth, sutures flush but dis- 

 tinct, oblique, apical end of test often with a spine; aperture with a 

 short neck at the acute end of the chamber, radiate. 



Length up to about 1.50 mm. 



Distribution. — The only previous record for this species in the 

 North Pacific is a Challenger station in 345 fathoms, Hyalonema- 

 ground off Japan, given by Brady. I have material from off the 

 Hawaiian Islands, Nero station 2071 in 271 fathoms; from off Japan, 

 Albatross station D4954 in 957 fathoms; and at four Nero stations,
