 bronze and blue, very dark, and therefore faint; a black spot at base of pectoral; head with wavy 

 blue stripes, lips yellow; dorsal colored like body, with blue edge; anal with blue edge and blue 

 median stripe, elsewhere dark bronze; caudal like body at base, with blue curved streak, posterior 

 part black, the edge pale; ventral blue, with black stripe; pectoral dusky greenish yellow at base. 



Another specimen from Apia was jet black, with two white longitudinal streaks, the upper from

 vertical bar of blackish on each scale; anal yellow and lower part of head yellow; spinous dorsal
