 (5)+ 1 +11 (10-12), total 16 (15-18); vertebrae 36 (35-37). 



Two prominent photophores on middle of cheek, well separated and on a line about paral- 

 lel with upper jaw. Anal origin about under beginning of last third of dorsal base. Prominent 

 secondary photophores on each scale pocket. Last 3 Pre in oblique line, the last (uppermost) on 

 level of lateral line at bases of caudal rays; Prc3.4 interspace slightly greater than the rest; Pre 

 and AOp continuous. AOa level, the space between the first 2 notably greater than those 

 between the rest. Infracaudal gland with 7 (8-9) luminous scales filling ventral surface of 

 caudal peduncle; supracaudal gland small, the scales varying in number from 3 to 4. Luminous 

 gland at base of adipose fin with 1 to 4 luminous scales. 



Size: To about 100 mm. 



Least depth of capture: To 70 m at night. 



Distribution: Known only from the southeastern Pacific Ocean off Chile, from about 21° to 

 48° S, 71° to 82° W.

Description 



D. 14-15; A. 18-19; P. 14 (13-15); AO 8-9 (10) + 8-9 (10), total 17 (16-19); gill rakers 4 -t- 1 -I- 

 9 (10), total 14 (15); vertebrae 39 (38-40). Body proportions are given in Table 38 and are 

 compared with similar data for a related species, L. lepidolychnus . 



PLO below lateral line, about one-third the distance from there to pectoral origin. PV0,.2 

 interspace about half that of PLO-PVO.. PLO and PVO,.- form straight, posteriorly slanting 

 line that passes slightly before PO^. P04 elevated to about level of middle of pectoral base, or 

 slightly lower, and to almost directly over PO:,. VLO over or slightly behind pelvic origin and 

 slightly above midway between that origin and lateral line. SAO, on level of or slightly higher 

 than SAO,, and about over midpoint between V0,..3 interspace. SAO, . . interspace nearly one and 

 one-half times that of SAOo.,. A line through SAO,. > passes slightly behind VO,. SAO, about over 

 anus; SAO., slightly before or behind vertical from AOa,. The 2 Pol and last AOa 

 form line that passes variously through, before, or slightly behind end of base of adipose fin. 

 AOa-AOp interspace equal to about half least depth of caudal peduncle and considerably 

 greater than space between Prc3.4. First 3 Pre equally spaced in curve; Prcj at end of lateral 

 line and separate from Prcj by space only little less than that between Pre, and PrCj. 



Size: To about 155 mm. 



Least depth of capture: To 70 m at night, off Chile.
