rays ; the pectorals are arched ; they are rather shorter than 
the head, and formed of fifteen rays, of which the first is 
short, and the third the longest of all, and extends further than 
the spines of the anal. The dorsal and anal are received in a 
low, scaly sheath ; the longest spines of the dorsal are equal to 
the diameter of the eye ; this same dimension is contained one 
and a-quarter times in the caudal at its centre, and twice on its 
sides. 
General colour silvery ; the upper parts are blue, and the 
sides have a copper tinge ; there are faint longitudinal lines, due 
to the centre of the scales being rather obscure. The spinous 
dorsal is purple, and the soft part rather yellow ; the caudal is of 
the latter colour ; anal, pectorals, and ventrals, pink eye 
yellow, the pupil rather angular. 
Seen several specimens in the month of July.
