A REVISION OF THE AUSTRALIAN ORECTOLOBIDZ. WG 
spiracle. Twotofour simple dermal lobes above the upper 
lip; several more or less branched lobes behind the angle 
of the mouth, followed by two posterior lobes which are 
simple and rounded in the young and branched in the adult. 
Width of interorbital region 5°00 in the length of the head. 
Branchial region 2°20 times the diameter of the eye. 
Length of head and trunk equalling that of the tail. First 
dorsal fin originating above the end of the base of the 
ventral and a little behind the middle of the length; anterior 
border of fin linear; hinder border 2°40 in the basal length, 
which is more than the vertical height of the fin; space 
between origins of dorsals 2°00 in that between the second 
dorsal and the tip of the tail; interdorsal space 1°90 in the 
base of the first dorsal and equal to the distance between 
the second dorsal and the anal. Length of caudal fin 5°15 
in the total length. Pectoral fin originating one-fourth 
nearer to the tip of the snout than to the ventral; all the 
borders convex; its base is 1°50 in its greatest width and 
1°65 in its length, which is 1°50 in the length of the head 
and 1°40 in the distance between its origin and the ventral. 
Origin of the ventral fin one-half nearer to the first dorsal 
than to the pectoral, its width 1°15 in its length, which 
is 1°50 in the head. Pale lilaceous gray, marbled and dotted 
with sandy-brown; trunk and tail with six broad irregular 
umber-brown cross-bands, which on the trunk encroach 
but little on the ventral surface but on the tail form com- 
plete or nearly complete annuli; these bands are them- 
selves ornamented with violet spots, which sometimes form 
ocelli; under surface yellowish white, the abdomen with a 
median row of violaceous spots and a few scattered spots 
some of which are faint; a conspicuous spot immediately 
in front of the vent. Head similar to the trunk, but with 
three large dusky blotches forming a crescentic band across 
the occiput and an angular lilac bar across the forehead 3 
two series of dark spots, one of which is much larger than
