This species, which is now known from this general region, from the 

 Hawaiian Isalnds, south to New Zealand, and westward to the 

 Kerimba Archipelago off southeastern 

 Africa, has been found to be a common 

 species in the Philippine region. Speci- 

 mens have occurred at 35 stations, ranging 

 in depth from 10 to 805 fathoms (18 to 

 1,472 meters), the average depth being 

 236 fathoms (432 meters) . Bottom tem- 

 peratures are given at 18 stations, ranging 

 from 43.7° F. to 79.5° F. (6.5° C. to 26. 3° 

 C), the average depth being 53.9° F. 

 (12.1° C). There does not seem to be 

 any particular depth at which it is particularly abundant. 



There is no great variation in its general characters, and on the 

 whole it forms a fairly well-defined species in the material. Most 

 of the stations are in the i\j-chipelago itself, but there are a few in the 

 182152—20 27
