12 ON NEW OR INSUFFICIENTLY DESCRIBED FISHES 



which is feohly curved anteriorly, from the upper angle 

 of the operclo to the root of the caudal ; the scales forming 

 the series through which this line runs are profusely dotted 

 with black, as also are the edges of all the scales above 

 the line, and anteriorly the surface of the scales is similarly 

 but more sparsely dotted ; two or three series of body- 

 scales below the line and the s(.ales of the tail with a single 

 marginal series of black dots. Upper surface of head and 

 nape and the opercles so profusely dotted as almost to 

 obscuie the ground color ; cheeks and lower surface of 

 head less closely dotted. All the fins similarly marked, 

 the dots b?ing most crowded on the membrane of the 

 second dorsal spine, the tips of the anterior anal raj^s, 

 and the middle ventral raj^s. 



Abundant in all creeks and waterholes in the Brisbane 

 district. Description taken from a 50 millim. example 

 in the A.F.A.Q. Museum, to which it was presented by 

 Mi. W. E. Weatherill ; Cat. No. 463.

 spine 1-5, longest r^nal 1-95, length of pectoral 1-3, of 

 ventral 1-45 in length of head. 



Upper profile of head linear, the nape feebly convex 

 and with a well defined median ridge ; interorbital region 

 convex ; maxillary extending to below the anterior border 

 of the eye. Preopercle with a few strong spiries at the 

 angle. Head scales a? large ae those of the body. 



No procumberit dorsal ?pine ; spinous dorsal fin origin- 

 ating above the 7th body scale, the 1st spine longest and 

 strongest, somewhat higher than the rayed dorsal ; spine 

 of soft dorsal 1-3 in the height of the spinous dorsal. Anal 

 fin originating below the 14th body-scale, the 3rd spine 

 longest, as long as that of the soft dorsal, a trifle loi^ger 

 than the base of the fin, and equal to the 1st ray, which 

 is higher than that of the dorsal. Caudal fin deeply forked, 

 the middle rays about two fifths of the leiigth of the lobes. 

 Fourth pectoral ray longest, extending to the 11th body 

 scale. Ventral a little shorter than the pectoral, the two
