No antorbital organs (upper represented by densely 
pigmented black globular body, apparently no longer

urolampus 
One antorbital each side, entirely above nostril; no 
supraorbital or suborbital luminous organs. 
Antorbitals very small, separated from each other 
by wide, median interspace. 
\ Upper supraanal and posterolateral in contact with 
or close to lateral line; supraventral nearer 
lateral line than ventral fin base. 
ii ♦ First anteroanal well elevated, nearly level with 
second supraanal; anala 6 or 7 + 5 or 6.agaasizi.

n. • First anteroanal well elevated; anals 5 f 5 or 6; 
2 3 upraanals; suprapectoral well below hind 
opercle angle; supraventral nearer ventral base 
than lateral line. - 
- gudgeri 
Upper supraanal and posterolateral well below lateral 
line; supraventral little nearer lateral line than 
ventral fin base; first anteroanal well elevated, 
series crescentic; intervals between last 2 pre-
