some Cossyphi, and on the mandibles these canines are inclined for- 
ward like the corresponding teeth in Anampses. There are no ca- 
nines at the angle of the mouth. The lateral teeth are incorporated 
with the bone, and are small and uniform, not decreasing in succes- 
sion, as in the Labri. In the young specimen the bone of both jaws 
is thin, and the forms of the lateral teeth are distinctly seen, cemented 
laterally to each other, with a few very minute granular teeth scattered 
on the interior surface of the bones; but in the older specimen the 
premaxillaries have swollen behind the canines and acquired a smooth 
surface by friction, and the edges of the jaws having worn down the 
forms of the teeth composing them, are obscured—their rounded 
points alone being visible. On the other hand the granular teeth on 
the sides of the jaws have become more conspicuous in consequence 
of their growth. 
The cleft of the mouth is small, not exceeding the diameter of 
the eye. The length of the preorbitar is greater. The latter bone 
and the suborbitar chain, with the lower jaw and top of the head, 
are scaleless. The edge of the preoperculum is quite smooth, and its 
disk appears to be scaleless, but there are nine rows of small scales 
on the cheek, and the other gill-pieces are scaly, those on the oper- 
culum and suboperculum being larger than the rest. The uncovered 
disks of the scales of the body are rough, with small round points, 
the edges being thin, membranous, and striated or wrinkled. The 
descending curve of the lateral line under the soft dorsal is the gra- 
dual one of a Cossyphus, not the more sudden deflection of a Labrus. 
Each of the scales composing it has a loose arbuscle of sparingly 
branched tubes. 
The dorsal spines are strong and comparatively short, and the an- 
terior ones are compressed so as to render their front edges acute. 
The compression diminishes in the posterior spines, and the last and 
tallest one is subulate, grooved and pointed. The foremost two anal 
spines are even more conspicuously compressed, and the third one is 
subulate. The ventrals are rounded, and have a compressed spine 
which stands under the second and third dorsal spines and base of the 
pectoral—being farther forward than in Cossyphus vulpinus. 
This fish is represented as having a dark purplish colour, and is 
said by Mr. Neill to bear the names of “ Koojenuck,”’ “ Quejuinuck,”’ 
or “ Knowl,” among the aborigines of King George’s Sound. It 
attains the weight of 28 or 30 lbs. It is described more at length in 
the ‘Ichthyology of the Voyage of the Erebus and Terror,’ quoted 
above. 
JULIS CYANOGRAMMaA, Richardson. 
Radii.—D. 9|13; A. 3|13; C.123; P.13; V.1]5, spec. 
This species is the “‘ Knelmick” or ‘‘ Kielnmick”’ of the aborigines 
frequenting King George’s Sound, and the “‘Common Rock-Cod” of 
the sealers. It is also an inhabitant of New South Wales, specimens 
of it having been sent to the Museum at Haslar by Mr. Miles. Its 
flesh is little prized. 
In the numbers of its fin rays it comes near Julis dussumieri, but
