This species is very rare as far as the records show, which is similar 

 to what I found in most of the North Pacific material." 



The only two stations from which it was found are D5439, west 

 coast of Luzon, in 940 fathoms (1,719 meters); and D5639, Molucca 

 Sea, 1,560 fathoms (2,853 meters). 



This seems to be much more common in the Atlantic than in the 

 Pacific.
