Specimens of this species occur in the material dredged bv the 

 Albat7'oss south of the Equator. The v/all in these specimens is very 

 granular, the aperture and sometimes the tube partially closed 

 by sponge spicules. The stations are as follows: D5613, off Celebes, 

 752 fathoms (1,375 meters), bottom temperature not given; D5650, 

 Gulf of Boni, 540 fathoms (988 meters), bottom temperature 40.1° 

 F. (4.5° C); and D5668, Macassar Strait, 901 fathoms (1,648 meters), 

 bottom temperature 38.2° F. (3.3° C).
