Regan is a.s follows Depth of body, in the length. 
Length of head 3^. Snout I diameter of eye. whieli is / 
2-} in the length of the head and equal to the interobrital 
width. JMouth oblique and lower jaw somewhat project- 
ing, 33 to 35 scales in a longitudinal series and 8 or 9 in 
a transverse oiie. Dorsal fin 4 spines, 11 soft rays. Anal 
1 , 18-19' Though young, my .specimens are in excellent 
colour showing clearly the characteristics of lln' adult 
fish, viz.: — Main body colour, a pale iridescent bluish 
silver, each scale betAveen the lateral line and dorsal 
being margined Avith black, giving a latticed effect. Those 
on the line itself froiin head to tail have much thicker and 
darker edges, thus giving the appearance of 2 straight 
black line.s. The scales beloAV the lateral line are ]iol 
margined, shoAving merely scatter<‘d dark spots. The 
disposition of the scales is in regular longitudinal roAVS. 
A dark spot at the base of each soft ray of dorsal and 
anal. Head olivaceous. All fins are orange margined 
Avith black, the caudal being forked. 
In comparison the mainland Atheidne (Melanotaemia 
nigrans) has the head forming a fifth part of the length, 
snout is flat. The diameter of the small eye is just equal 
to the portion of the snout lying before it. ci.f., the short 
snout of R. ornatus. 
Fins, dorsal (1), 1 spine, 4 rays (2), 1. 12. Anal 1, 
18. The scales are only 30 on the lateral line and 10 
transversely. 
Colouring most A^ariable as regards markings, they 
sometimes being black and at others scarlet. An eA'en 
stripe (red, or black) runs along the lateral line from the 
base of the tail and is continued forAvard over Ihc gill 
cover ripper half of the eye and sides of the snout. Some- 
times the scales are bordered Avith black or red and at 
others merelv sIioaa' dots. There are no markings hcloAA^ 
the line. The fins are usually colourless margined Avith 
black. 
This form of the mainland seems to be absent from 
Moreton Island.
