 This species, which seems to be a typical one of coral-reef regions, 

 is fairly common in the Philippine area. All 28 stations at which it 

 is recorded are in the Archipelago proper, none of the records being 

 from the regions to the south. This is probably because those stations 

 represent deeper water stations, and it is pro!) ably found in shallower 

 water, as recorded b}'^ Millett and Chapman. The stations range in 

 depth from 10 to 318 fathoms (18 to 582 meters), with the average 

 depth 45 fathoms (82 meters) . Bottom temperatures are given but 

 for three stations, ranging from 52.9° F. to 75.7° F. (11.6° C. to 

 26.3° C), the average temperature being 62.3° F. (16.7° C). As 

 the stations at which bottom temperatures are lacking are mostly 

 those in the shallower water, the average bottom temperature would 

 probably be nearer the maximum given here. From the records the 

 species seems to be commonest in waters less than 30 fathoms (55 

 meters), and less frequent at depths greater than these. There is 

 some variation, but on the whole the specimens are rather typical 

 in their characters. From the available records this seems to be a 

 species ranging from the Hawaiian Islands on the east to the Kerimba 

 Archipelago and the Red Sea on the west.
