The occuiTence of this species in the Philippine material seems to 

 indicate that it is not common in warm waters compared to its 

 abundance in cooler shallow v^^aters. It is worthy of note that the 

 bottom temperatures of the Philippine stations at which this species 

 occurred and where temperatures are given range from 41.2° to 44,3° 

 F, (5,1° to 6.8° C), which for this material are decidedly low tem- 

 peratures. The depths range from 20 to 750 fathoms (37 to 1,370 

 meters), with the average 282 fathoms. In the Archipelago the 

 species occurred near Basilan Island, in the Sulu Archipelago; 

 vicinity of Jolo; off northern Cebu; and east coast of Mindanao. 

 Except at the last locality, where it was frequent, the species is com- 

 paratively few in numbers. To the southward it occurred at a few 

 stations off Sibuko Bay, Borneo; Gulf of Tomini, Celebes; and 

 Flores Sea.

This interesting species, which is now known from several stations 



in the Indo-Pacific, has occurred at two Philippine stations — D5201, 



Sogod Bay, southern Leyte, 554 fathoms (1,012 meters), and D5277, 



China Sea, off southern Luzon, 80 fathoms (146 meters).
