"fangs" on palatines. Three or 4 (rarely 5) AO behind anal base, the last few below level of 

 preceding ones. 



Both sexes bear single, small, scale-like supracaudal and infracaudal luminous glands. 



Size: To about 100 mm. 



Least depth of capture: Andriashev (1962) reported captures with wire lengths of 1000 to 

 4700 m. 



Distribution: Between 40° and 68° S in the South Pacific.

(Giinther, 1878) 



Fig. 16— Electrona antarctica, male, 66.5 mm. From Andriashev (1962, p. 241, fig. 18). 



Description 



D. 14 (13-15); A. 20-21 (22); P. 12-13; AO 17-18 (16-19); gill rakers 4-5 -(- 1 -h 12-14, total 

 18 (17-20); vertebrae 40 (39-41). No So. SAO3 nearer lateral line than to SAO,. Pre usually 

 separated by 1.0 to 1.5 diameters. Palatines bear 7 to 9 rather large, curved "fangs". Four (3-5) 

 AO behind end of anal base. 



Supracaudal glands of males with 6-7 (8) rounded spots ringed with dark pigment (Fig. 3); 

 infracaudal glands of females with 1 to 3 weakly developed grayish spots, weakly outlined 

 with dark pigment in adults; both glands are evident at about 40 mm. 



Size: Males to 82 mm, females to 110 mm (Andriashev, 1962). 



Least depth of capture: To 100 m. 



Distribution: Circumglobal, usually south of the Antarctic Convergence; smaller speci- 

 mens often range somewhat farther north. Reported to be the most common myctophid in 

 Antarctic Waters.
