scales only, absent posteriorly. Dorsal 10-11, with 8 or 9 branched

 advance of the dorsal, extending to the anal. Caudal forked.

 with silvery reflections ; an indistinct stripe from operculum to 

 base of caudal ; a blackish spot on the middle of the dorsal fin ;

 of the third branched ray ; dorsal and anal yellowish ; caudal pink,

Here described from two specimens, 32 and 36 mm. in total
