about 1°50 times the diameter of the eye and 2°25 in the 
basal length, which is rather more than the vertical height 
of the fin: second dorsal as long as but not so high as the 
first, its distance from the origin of which is 1°75 in that 
from the tip of the tail. The distance between the origin 
of the anal and the second dorsal is 1°65 in the free space 
between the dorsals and 4°50 in its distance from the ven- 
trals; its height is about 3°00 in its base, which is only 
separated from the caudal by a notch. Length of caudal 
fin 5°50 in the total length, its extremity acute, the tip of 
the vertebral column extending for some distance behind 
the fin. Pectoral fin obovate, originating somewhat nearer 
to the ventral fin than to the tip of the snout, its base 1°80 
in its greatest width and 3°20 in its length, which is 1°35 
in the head. Origin of the ventral fin much nearer to the 
first dorsal than to the pectoral. Back with a conspicuous 
ridge between the dorsal fins. Cream colour, tinged along 
the dorsal edge with buff; tip of snout and upper surface 
of head between and behind the eyes violaceous-brown, 
this colour passing forwards below the eyes, which are 
rimmed with pale blue, to form two broad bands on the 
sides of the head, the anterior running downwards and 
forwards to the corner of the mouth, the posterior directly 
downwards to the lower surface, which is immaculate; 
branchial region dusky. Body and tail with eight broad 
brown cross bands, the last five forming perfect rings and 
having a supplementary bar across the lower surface 
between each pair of rings; a dusky spot below the end of 
the pectoral. Dorsals and anal mostly brown; pectorals 
and ventrals tipped with violaceous-brown, the former with 
a small round spot about the middle of the anterior margin; 
(punctatum, minutely dotted). 
From the Malay Archipelago (Java) eastwards along the 
coasts of intertropical Australia, and ranging southward on 
our shores at least as far as Moreton Bay. From the
