This species has been found several times attached to various 

 genera of foraminifera or to shells or pebbles. It is most frequent 

 in shallow water, but the depths have ranged from 18 to 494 fathoms 

 (33 to 903 meters). The only stations at which the bottom tem- 

 perature is given are D5236, 494 fathoms (903 meters), 41.2° F. 

 (5.1° C), D5217, 105 fathoms (193 meters), 63.1° F. (17.2° C), and 

 D5538, 256 fathoms (468 meters), 53.3° F. (11.8° C).
