This is another species with a peculiar distribution so far as avail- 

 able records show. Brady described it from off Culebra Island, 

 West Indies, in 390 fathoms (713 meters), and Flint records it from 

 the Gulf of Mexico, 200 to 1,200 fathoms (366 to 8,366 meters). 

 Chapman records it from off Funafuti in 200 and 1,485 fathoms 

 (366 and 2,716 meters), in the lagoon, one specimen in 7| fathoms 

 (13.5 meters); and I have had it from the Western Pacific in 814 

 and 1,040 fathoms (11,476 and 1,902 meters). In the Albatross 

 Philippine Expedition it was dredged at station D5650, in the Gulf 

 of Boni, in 540 fathoms (988 meters).
