Photographs of an otolith of L. urophaos (Nafpaktitis and Paxton, 1968) and of L. u. 

 atlanticus (Kotthaus, 1972) show striking dissimilarities that approach the familial level and 

 indicate a possible aberrance in formation or an error. 



Nafpaktitis (personal communication) has found the more posterior position of PVO, to be 

 inconstant, a significant number of specimens having PVOi directly below PVO^. Thus, in 

 view of this inconstancy, the apparently excessive difference in shapes of otoliths, and an only 

 slight difference in lengths of supracaudal luminous gland with size offish, more study is 

 needed, particularly on otoliths, to validate the subspecific distinction. Pending this study, I 

 retain L. urophaos at the full species level.

ll,fig.3). 



Description 



D. 14(13-15); A. 14 (15); P. 14(15); AO 6-7 + 3-4 (5); Pre 2 + 1; PO 5 (6); VO 5 (4-6); gill 

 rakers 6-7 -I- 1 + 12-14, total 19-22; lateral line scales 39-41; vertebrae 38-39 (40) (five 

 specimens). 



Eye large, 2.7 to 3.2 in head. Opercular margin not pointed but with a shallow indentation 

 about at level of pectoral origin. Pterotic spine strong, straight, directed posterolaterally. 



Supracaudal luminous gland one-half to two-thirds the length of infracaudal; posterior 

 margin of supracaudal distinctly notched. Distance from end of anal base to anterior end of 

 infracaudal 1 to 1.5 times the length of the gland. 



Size: To 130 mm. 



Least depth of capture: To 60 m at night and 100-700 m in daylight. 



Distribution: In southeastern Pacific off Chile at about 34° S, 73° 30' W. Also known from 

 North Atlantic and southern Indian Oceans, and off New Zealand.
