 two spines, the lower the longer ; post-clavicle with a few coarse denticles ; humeral

Teeth as in y. unicolor. 



Scales in 63 series above, 58 below the lateral line ; transverse series from 

 below origin of dorsal 10/1/23 ; cheek-scales in 7 series. Lateral line tubes 56. 



Dorsal fin with xii 13 or 14 rays, originating above the pectoral- base, the 

 length of the soft portion 1-6 to I-75 in that of the spinous, which is low, with the 

 spines strong and pungent, the 1st very short, less than a fourth of the 5th and 6th, 

 which are the longest, 2-5 to 2-67 in the length of the head ; beyond these they are 

 finely gTaded to the last, which is nearly as long as the 3rd and 1-3 in the longest 

 spine ; soft dorsal rounded, the antero-median spines the longest, 1-3 in its base, and 

 from one tenth to two sevenths more than the longest spines. Caudal fin rounded, 

 the middle rays 4-8 to 5 in the body-length. Anal fin with iii 11 or 12 rays, originating 

 below the last dorsal spine ; spines short and stout, curved, the 1st 1-67 in the 2nd, 

 which is stronger and a little longer than the 3rd, 2-65 to 2-75 in the length of the 

 head, and 1-15 to 1-33 in the longest ray; soft fin similar to but much shorter and

 Pectoral obtusely pointed, with 16 rays, the 6th the longest, 4-6 to 4-85 in the body- 

 length. Ventral inserted behind the pectoral base, pointed, the spine moderate and 

 rather short, 1-67 to 1-8 in the fin to the ti]} of the outer ray, which is slightly produced, 

 a little shorter than the pectoral, 1*65 to 1-8 in the length of the head, and extending 

 to midway between its origin and the 3rd anal ray. 



Gill-rakers 5+11, I'ather short and stout, the longest about one third of the 

 eye-diameter. 



Uniform blacldsh. {carbo, a lump of coal.) 



Described from two specimens, measuring respectively 150 and 182 millim., 

 collected by Dr. Bancroft in the upper waters of the Gregory River, District of 

 Carpentaria. * 



Regarding this fish Dr. Bancroft Avrites — " I found this black fish at Gregory 

 Plains, south-west of Burke town, where it is common ; when fishing for it I found 

 that it behaved in exactly the same manner as I have already described the Eureka 

 Creek fish as doing {see ]). 120). It is a fine game fish, gi'owing to a weight of four 

 pounds and over, and is of excellent quality for the table."
