Distribution. — Brady records this species from the South Pacific, 

 but in "The Summary of Results" of the Challenger expedition it 

 is only given from two stations, 237 and 246, in 1,875 and 2,050 

 fathoms, one station east of Japan, the other in the middle of the 

 North Pacific. 



No typical example of this species was noted in the North Pacific 

 material I have examined. Two specimens from Albatross station

D4957, in 437 fathoms, may possibly belong here, but the central 

 enlargement is not very pronounced.

Description. — Test free, tubular, cylindrical or fusiform, sometimes 

 recurved at the ends, apertures formed by the open ends of the tube, 

 wall composed wholly or in part of sponge spicules, thin but firmly 

 cemented together. 



A single species has been found in the North Pacific, and that has 

 occurred at but few stations. It has been found in the colder por- 

 tions of the North Atlantic.
