Specimens referable to this species were obtained in material from 

 but three stations, D5138, in 380 fathoms (700 meters). Pacific Ocean, 

 east coast of Mindanao, bottom temperature 43° F. (6.1° C); D5268, 

 170 fathoms (311 meters), Verde Island Passage; and D5445, east 

 coast of Luzon, 383 fathoms (699 meters), bottom temperature 44.3° 

 F. (6.8° C). 



In the North Pacific material this species occurred only from the 

 Hawaiian Islands. Apparently it is not common as far as the North 

 Pacific is concerned.
