between Gillolo and Kayao; Patiente Strait; Pitt Passage; off Bouro 

 Island; Molucca Sea; and Gulf of Boni. Besides these regions, most 

 of which are outside the Philippine Archipelago proper, the species 

 has occurred on the Pacific side of Luzon and Mindanao; Verde 

 Island Passage; between Burias and Luzon; and in Sogod Bay, 

 southern Leyte. 



These stations range in depth from 80 to 1,570 fathoms (146 to 

 2,871 meters), with the average 428 fathoms (783 meters). The 

 average bottom temperature was 51.9° F. (11° C); but this is too 

 high, as the bottom temperature is not given for many of the deeper 

 stations. 



The specimens are very typical, but only at Albatross station 

 D5236, in 494 fathoms (903 meters). Pacific Ocean, east coast of 

 Mindanao, could it be called abundant. There specimens were very 

 abundant and well developed. The bottom temperature there, how- 

 ever, was 41.2° F.
