Size: To about 30 mm. 



Least depth of capture: At surface at night. 



Distribution: Becker (1964a) stated: (translation by Edith Roden) "Although our material 

 is scanty, its fortunate geographical distribution permits us to conclude that, within its entire 

 range, L. terminata does not occur to the south of the North Tropical Convergence and that in 

 its western part it does not touch the Kuroshio Convergence, nor in its central and eastern part 

 the waters of the North Pacific Drift and the California Current. Thus, the range of L. ter- 

 minata lies completely within the borders of the western and eastern North Pacific Central 

 Water masses, at the northern boundary of the distribution of the tropical species of myctophids 

 (Parin, 1961)." 



Loweina laurae 



Wisner, 1971* 



Fig. 65 — Loweina laurae, holotype, male, .36.8 mm. 



Description 



D. 11-12 (10-13); A. 15 (13-17); P. 10-11 (9-13); AO 6 (4-7) + 5 (4-6), total 11 (8-13); gill 

 rakers 2 (always) + 6 (4-7), total 9 (7-10); vertebrae 38 (37-39 ). Correlated counts of dorsal 

 and anal fin rays and AO photophores are given in Table 13. 



Two SAO, the lower over anus and about its diameter behind VO^; the upper, one or two of 

 its diameters below lateral midline. Four VO, the series curved, the VOi.j interspace slightly 

 greater than the others. Dorsal origin slightly behind midbody and about over midpoint be- 

 tween origins of pelvic and anal fins; anal origin under last third of dorsal base. Caudal 

 peduncle short, about 5 in SL, and moderately deep, its depths about equal to orbit length. 

 Lateral line incompletely developed, an average of 12 (2-19) perforated scales, at anterior end 

 only (Table 14). 



Supracaudal luminous gland large, undivided, filling about 70% (50%-85% ) of supra- 

 caudal space. Females bear no caudal luminous glands. 



Size: 36.8 mm, the largest of 93 specimens. 



Least depth of capture: At surface at night. 



*As stated in Copeia (1972: (1): 206— Erratum), fig. 4, p. 46, in Copeia, 1971 (1) is incorrectly 

 stated to represent the holotype of Loweina laurae. Instead, it represents a specimen that was 

 originally a syntype of Scope lus (Rhinoscopelus) rarus Liitken, 1892, and subsequently a 

 syntype of Myctophum interruptum Taning, 1928. This specimen has been selected and labeled 

 as the lectotype of Loweina interrupta (Taning) and is so designated below.
