traceable posteriorly; it originates above the operculum and is 
curved upwards towards the back, with which it appears to run 
nearly parallel to the end of the dorsal fin. 
Dorsal commencing above the end of the operculum, the first 
spine rather short, the next two increasing rapidly in length, the 
others becoming gradually longer to the last. The margin of the 
fin is almost straight, the soft portion broadly rounded behind. Anal 
of similar form to the dorsal. Upper pectoral rays longest ; the 
margin of the fin rounded. First ventral ray a little produced, and 
somewhat longer than the pectoral fin. Caudal slightly emarginate. 
Colour. — Head grey, with large yellow spots. The anterior 
portion of the body and chest is bright yellow shading into white, 
this colour forming a sharp line with the deep black of the rest of 
the body which forms a backward curve from the first dorsal spine 
to the ventral fin. The black colour projects forward behind the 
pectorals on to the coracoid bone, and the basal half of the pectoral 
fin is also of this colour. Ventrals yellow with white tips. Dorsal 
and anal black like the body, as is the greater part of the caudal 
which bears a lunate, yellow, submarginal band with a narrow 
blackish border. 
Described from a single example, 290 mm. long, from Shark 
Bay. 
I am indebted to Mr. W. B. Alexander for notes on the life- 
colours of this specimen. 
The colour pattern distinguishes this species from all others of 
the genus known to me, though I have been unable to compare it 
with H. zebra, H. regime, and H. caudibicolor of Lienard. 1 It appears 
to be nearest allied to H. conspicillatus, Waite. 2
