Sir J. Richardson on Australian Fish. 289 



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.

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 

 diifers from it in having smaller scales, in form and in colours ; nor 

 have I been able to refer it to any described species. Its body is 

 elongated ; its height, which is not equal to the length of the head, 

 being contained five times and a half in the total length of the fish, j 

 caudal included. The compression of the head is considerable, its ' 

 thickness not exceeding half its height, and the occiput and nape are 

 acute. The length of the preorbitar is considerably greater than the i 

 diameter of the eye, and the cheek and interoperculum are both high. ' 

 There are no scales on the temples or any other part of the head. 

 There are fifty scales on the lateral line, each marked by six or j 

 seven short, simple, diverging tubes. The lateral line is bent down- 

 wards under the ninth, tenth and eleventh soft rays of the dorsal ; it 

 is otherwise straight, and runs near the back. The dorsal commences 

 far forward, over the top of the gill-cover, and runs back wiXh. an even 

 outline ; its tip, which is acute, though not prolonged, reaching, when 

 laid back, to the base of the caudal. Its spines, as well as those of ; 

 the anal and ventrals, are flexible and very slender. The pectorals 

 are not large, and the ventrals have tapering, acute, but not filament- 

 ous tips. They stand under the base of the lowest pectoral ray. 

 The caudal is moderately rounded, and it is scaly between the rays i 

 for more than on^third of its length. ' 



When the open mouth is viewed in front, its teeth form a rhomb ; 

 the front pair of teeth above and below are comparatively large and 

 are curved. There is also a small curved tooth standing forwards 

 from the angle of the mouth. 



Mr. Neill's drawing represents this fish as having an aurora-red 

 ground colour on the head, back, dorsal and anal fins, the fins being 

 of the deepest tint. The head is ornamented by deep blue lines, 

 which are distinctly visible on the dried specimen. These all form 

 curves more or less bold, with the convexity forwards. The anterior 

 one begins on the nose, runs forward to the lips, and inclines backwards 

 again on the lower jaw ; the next descends from the nostrils over the 

 disk of the maxillary and posterior part of the lower jaw. Two de- 

 scend from the orbit over the interoperculum, and there are some 

 finer intermediate ones which vanish on the cheek. There are also
