 Height somewhat above or below 5, head 3 3 ! / 2 , eye 3*/ 2 

 to more than 4, ] /s longer than rounded snout. Upper jaw 

 with its hinder end scarcely dilated, surpassing eye by about 

 one eye diameter. Praeopercular margin oblique. Origin of 

 dorsal above origin of ventrals, before middle of length. Origin 

 of anal slightly behind end of dorsal, somewhat before be- 

 ginning of last ! / 3 of length, ending below adipose fin. Pectorals 

 far below middle of height, not reaching the ventrals. Caudal 

 forked. Scales cycloid. Luminous organs: 2 united antorbital 

 organs before anterior border of eye, not extending on ven- 

 tral orbital margin. 2 operculars, obliquely above each other, 

 the smaller lower one behind upper jaw; 3 branchiostegals ; 

 5 PO, the fourth outside the series, far above the space 

 between third and fifth, first and second far more distant than 

 the following. The 2 PVO in an oblique line, the superior 

 before the ventral base of the pectoral, the inferior above the 

 space between the first and second PO. PLO between 

 lateral line and upper pectoral base, nearer to lastnamed, at 

 its lower border a large, luminous scale. 5 VO, the second and 

 third outside the series, the third higher than the second. 

 10 13 AO in two groups, the anterior above the anal with 

 5 7, the anterior and posterior of which are situated higher 

 up outside the series, the first upwards before or above the 

 second ; the posterior group contains 4 6 organs, in one series 

 behind the anal, the last of them generally smaller. 4 Prc, 

 the hindermost distant from the 3 anterior and situated close 

 to the lateral line. VLO between ventral and lateral line, 

 much nearer to lastnamed. 3 SAO in an oblique or very 

 slightly concave, ascending line above the space between 

 last VO and vent; the middle one close to it, the uppermost
