midway between upper clef of gill opening and caudal base; A.Ill, 10, I , 
third ray 2 l/4, fin origin opposite base of tenth dorsal ray; caudal 1 l/3 (?) 
forked, rudimentary rays 5 or 6 (?) above or below, inconspicuous; least depth

Diagnosis . Allied with Bathytroctes squamulosus Alcock but with larger 
maxillary as in that species it only reaches about opposite middle of eye. My 
specimen also shows a more advanced anal. Its character of affiliation seems 
to be its long pectoral. Bathytroctes squamulosus shows a more forward vent,, 
which about opposite middle of dorsal base while my species shows it abovit 
last 2/5 of dorsal base and close before anal fin origin.
