A REVISION OF THE AUSTRALIAN ORECTOLOBIDZE. 297 
and second dorsal 1°25 in the free space between the dorsals 
and 2°00 in its distance from the ventral; its height is 2°55 
in its base, which is contiguous to the caudal. Length of 
caudal fin 1°90 in the total length. Pectoral fin obovate, 
originating midway between the tip of the snout and the 
ventral fin, its base 1°30 in its greatest width and 1°90 in 
its length, which is one-tenth more than that of the head. 
Origin of ventral fin three-fourths nearer to the first dorsal 
than to the pectoral. Dorsal surface with a strong median 
ridge, clothed with enlarged scales, from between the eyes 
to the first dorsal; on each side above, a similar but less 
conspicuous ridge, commencing a little in advance of the 
branchial region and disappearing below the second dorsal. 
Rich chestnut-brown above, the head and trunk with four 
narrow golden transverse bars; the first crescentic, 
between the second pair of gill-openings, and curving for- 
ward upon the interorbital region; the second between but 
not nearly reaching to the base of the pectorals, its lower 
extremities expanded and claviform, and sometimes ex- 
tended for some distance backward and downward; mid- 
way between these bands isa small golden bar crossing the 
dorsal ridge; the third behind the base of the pectoral and 
the fourth below the first dorsal, both extending downward 
to the level of the pectoral; between each of the two last 
pairs is a median golden bar similar to that between the 
first pair, below which is a long narrow vertical spot, 
sometimes forked inferiorly, which may be absent between 
the middle pair or broken up into several spots between 
either pair; lower portion of the sides of the trunk lighter 
brown with some scattered darker spots; under surface of 
head and trunk yellowish; a short, curved, golden bar 
across the snout and an oval spot in front of the gill-open- 
ing present or absent: upper half of tail with twenty-one 
continuous alternate bars of chestnut and gold, the former 
much the broader; below paler brown, with a correspond-
