This species is represented by a few specimens at but six stations, 

 all but one, D5446, east coast of Luzon, in the region to the south, 

 where it occurs in Sibuko Bay, Borneo ; south of Patiente Strait ; Mol- 

 luca Sea; and the Gulf of Boni. These stations are all in com- 

 paratively deep water, ranging from 300 to 1,560 fathoms (549 to 

 2,853 meters). Bottom temperatures are given at but three 

 stations— 38.3° F., 38.7° F., and 44° F. (3.5° C, 3.6° C, and 6.6° C). 

 This is a species which occurs in deep water in most parts of the 



ocean.
