above it. Upper surface of head with a pair of median longitudinal 
ridges, which commence on the sides of the postorbital processes, 
run parallel to one another but well separated to the middle of the 
interorbital region, where they gradually diverge to form gentle 
curves, which enclose a narrow spatulate area ; the posterior con- 
vergent portions do not, however, meet, and are separated irom the 
short nuchal ridge by a considerable hiatus : a well developed supra- 
nasal ridge forming a Y-shaped band, with the premaxillary ridge : 
supraciliary ridges smooth in front, feebly denticulate behind : a 
supplementary ridge leaves the supraciliary ridge opposite to the 
middle of the eye and on the temporal region breaks up into several 
divergent ridges, one or more of which may be branched ; all these 
ridges are smooth but end in a blunt point : articular bones with, 
coarse, smooth, flabelliform striae. Dorsal fin originating above the 
opercular membrane ; 4th. spine longest, longer than the eye, If in 
the length of the head and If in that of the 2nd. ray ; last dorsal 
spine f- of the longest. Anal originating below the last dorsal spine, 
the 4th. spine longer but much weaker than the 3rd., 2 in the length 
of the head and If in the 2nd. ray, which is a little longer than 
that of the dorsaL Middle caudal rays 2-f in the upper lobe, which 
is 3^ in the length of the body ; least depth of peduncle 1-?- in the 
diameter of the eye. Pectoral fin extending to the vertical from the 
vent, 1|- in the length of the head. Ventral shorter than the pectoral, 
reaching the vent. Gill-rakers 13 + 27, the longest % the diameter 
of the eye. Pale yellow, each scale of the back with a broad reddish 
brown band, which covers the whole scale except a narrow basal 
bar; on the sides the dark band gradually decreases in width until 
below the lateral line it is represented onlv by a narrow median 
vertical bar, which finally disappears : head above brownish yellow, 
the ridges darker : fins hyaline, the pectoral with a dark axillary 
spot, which is continued downwards to cover all the upper half of 
the base posteriorly, [australis, southern].
