 dorsal fin rays 16 or 17 (17), usually 16; segmented anal fin rays 

 17 or 18 (18), usually 18; posteriormost anal pterygiophore supporting

 gill-rakers on first arch 16-19 (17); pseudobranchial filaments 5 or 

 6 (6); vertebrae 35; supraorbital cirri 5-8 (8); supraorbital cirri 

 variable, sometimes arising from a common base, sometimes from 

 both mesial and lateral edges of main, or longest cirrus; nape with 1 

 cirrus on each side; predorsal commissural pores 3, apparently un- 

 varying; preopercular series of pores with all positions with simple 

 pores; 1 pore before each anterior nostril; lateral line terminating on 

 side in area below and between dorsal spines 10 and 11 (11); ventral
