Although fairly .well distributed the species was recorded as oc- 

 curring at but one station outside the Philippines proper — at D5665, 

 in 1,008 fathoms (1,844 meters), Macassar Strait. In the Archipelago 

 it occurrs on both the southwestern and eastern coasts of Luzon; 

 Verde Island Passage; east coast of Mindanao and Gulf of Davao; 

 Sulu Sea and Palawan Passage; thus not being recorded except in 

 waters either on the outer side of the Archipelago or in the direct 

 connections with interior waters. Stations range in depth from 49 

 to 1,008 fathoms (90 to 1,844 meters), with the average 397 fathoms 

 (727 meters). Bottom temperatures range from 40.6° to 56.4° F. 

 (4.7° to 13.5° C), the average 46.5° F. (8.0° C).

This species seems to be rare in the region, having been noted at 

 but three stations, all near Luzon, as follows: D5219, in 530 fathoms 

 1 969 meters), between Marinduque and Luzon; D5468, in 569 fathoms
