266 RECORDS OF THE AUSTRALIAN MUSEUM. 



slightly produced at the margin; the lower jaw is very acute; 

 the cleft of the mouth sub-horizontal ; the maxillary narrow and 

 extending to beneath the anterior margin of the eye. The nostrils 

 of each side are close together, rather nearer to the eye than the 

 end of the snout. The subopercle is moderately developed, but 

 the interopercle is very small and fails to cover the branchiostegals. 

 A single series of small teeth in each jaw, on the vomer and 

 palatines. 



The body is compressed, becoming more so posteriorly, and 

 below, especially behind the ventrals : it is elongate, evenly and 

 similarly curved above and below. 



The dorsal fin commences midway between the end of the snout 

 and the middle caudal rays, and is one-fourth higher than long ; 

 the first divided ray is the longest, the others regularly decrease 

 to the last, which is less than half the length of the longest ; the 

 adipose fin lies much nearer to the base of the caudal than to the 

 dorsal, its length equals the diameter of the eye. The anal com- 

 mences beneath the dorsal rays, when depressed, and extends to 

 beyond the adipose fin ; its length is slightly greater than its 

 height, and its anterior rays equal to those of the dorsal. To 

 these the pectoral is also nearly equal, its upper rays are the 

 longest. The ventral is situated wholly in front of the dorsal; it 

 is rather shorter than the pectoral. The caudal is equal in length 

 to the head, it is forked, with the lobes equal. The peduncle is 

 strongly compressed, its height equal to twice the diameter of 

 the eye. 



Scales. — The whole head is naked, and on the occiput is sharply 

 defined from the scaly body. The scales are of moderate size, thin 

 and cycloid. The lateral line is traceable only on the hinder half 

 of the body, being well pronounced posteriorly, but not apparent 

 in advance of the ventrals ; it occupies a median position. 



Colours. — Head and body above, olive, this colour separated 

 from the yellowish tint of the lower surfaces by a dark grey 

 streak, about half-an-eye diameter in width, passing the whole 

 length of the body in a median position. On this streak the 

 lateral line is placed. All the fins colourless, the dorsal fin has a 

 dark band running along its middle. 



Length of specimen, 200 mm. 



I may be unfortunate in having drawn what I believe to be a 

 slightly abnormal specimen, though the only feature in which this 

 is apparent is in the number of dorsal rays ; there are twelve 

 instead of the previously described ten, the latter number also 

 found in our Snowy River example. As, however, rays are liable 

 to vary in number, and much more so than spines, such a difference 

 is of small account; moreover the anterior rays are so very close 

 together that any addition to the length of the tin would be 

 inappreciable.
