Description 



D. 14 (21-15); A. 20 (18-21); P. 13-14 (12-15); AO 5 (4-6) + 11 (9-12), total 15-16 (14-17); gill 

 rakers 4 (3-5) + 1 + 10-11 (9-12), total 16 (15-17); vertebrae 37-38 (39). 



PLO several of its diameters below lateral line; VLO, SAO;,, and upper Pol and Pre at lateral 

 line. VO2 elevated and displaced forward to about its diameter before VOi. AOa evently spaced 

 in marked curve. Prc^. notably offset behind line through Pre,, Prc;,, and Prc^. Usually 4 

 AOp over anal base. Infracaudal gland with 8 (7-9) luminous scales, nearly filling infracaudal 

 space. Pectoral fin reaches to Pol. 



Size: To about 80 mm. 



Least depth of capture: Taken only in hauls from 0-2000 m. 



Distribution: L. hubbsi may be confined to the east-central portion of the equatorial region 

 of the Pacific Ocean (Fig. 176). The pattern of distribution reflects the track of the expedition 

 that captured the study specimens. The species is infrequently taken, with no more than eight 

 specimens in one haul.

Description 



Principal dorsal rays 11 (10-12); A. 18 (17-20); P. 16 (14-17); AO 7 (6-8) + 9 (7-10), total 16 

 (14-18); gill rakers 6 (5-7) + 1 + 14-15 (13-16), total 22-23 (20-24); vertebrae 39 (38-40). 



The abruptly elevated A0a2, AOa,.;, and often A0a4 (Fig. 179), and the extra photophore 

 close above pectoral origin, will, in combination, immediately identify this species. Also, the 

 pectoral fins are not as long or broad-based as in most of the species having tiny secondary 

 body photophores. PO4 elevated high, about on line through PVO,, VLO, and SAOi.j. 



Size: To about 115 mm in northeastern Pacific; lengths of 140 mm reported from Okhotsk 

 Sea. 



Least depth of capture: To 200 m at night. It has been taken at surface at night once, by 

 dipnet and surface light. 



Distribution: All known capture localities oiL. jordani are shown in Fig. 180 (solid 

 circles). The one occurrence off Santa Catalina Island, Southern California (an adult, 116 mm) 

 no doubt represents a stray. The species has not before been taken to the east or south of the 

 depicted range. Localities shown in Fig. 180 (solid circles) include those of various authors, as 

 listed by Wisner (1970b, fig. 2).
