Island, electric light, surface, August 3, 1909, 2 males; northern Min- 

 danao, Opol, electric light, surface, August 4, 1909, 2 males. Hawai- 

 ian Islands : Albatross station 3812*, 3829*, 3921*, identified by A. E. 

 Ortmann (1905). Gilbert Islands*, identified by H. J. Hansen 

 (1912). 



Distribution. — Western and tropical Atlantic, West Indies, Gulf 

 of Siam, East Indies, Philippine Islands, Great Barrier Reef Lagoon, 

 and Hawaii. 



Remarks. — This species is abundant in the waters of the East In- 

 dies and Philippine Islands. Breeding females are recorded for 

 January, June, and July, and it is probable that the species breeds all 

 the year around. Most of the records from the Philippine Islands 

 are of specimens captured in darkness at the surface by tow nets fitted 

 with electric light. The majority of the specimens thus taken were 

 males. In the large catches at Nasugbu Bay and Lagonoy Gulf I 

 estimate that more than 90 percent of the specimens were males, while 

 at all the other stations males alone were taken.
