A specimen referable to this species occurred at Albatross station 

 D5144, off Jolo in 19 fathoms (35 meters). It is close to Brady's 

 figure. The species seems to be largely recorded from the Indo- 

 Pacific in comparatively shallow water. A few specimens were ob- 

 tained at D5236, in 494 fathoms (903 meters), off Mindanao.
