rounded arid but little acclivous from the forehead to the dorsal fin, its width 24, 

 its depth 1-15, in its length, which is 3 to 3-25 in that of the body. Snout short 

 and obtuse, with strongly convex, anteriorly subvertical profile, its length 14 in 

 the eye-diameter, which is 2-65 to 2-9 in the length of the head; interorbital 

 region mesially flattened, its width 3-2 in the head. Mouth small and oblique, 

 the jaws equal; maxillary extending to below the anterior border of the eye. 



Scales 5/56/19. Lateral line forming a long shallow curve to about the 

 first third of the peduncle. 



Dorsal fin originating above the opercular flap, with xi, i 20 rays, the 

 spinous portion 14 in the soft ; spines weak and flexible, the 5th the longest, 2 to 

 2-25 in the length of the head, the last spine short and isolated; soft dorsal low, 

 about one sixth lower than the spinous. Caudal forked, the middle rays 14 in 

 the upper lobe, which is 345 in the body-length. Anal originating below the 1st 

 dorsal ray, with iii 19 rays, spines short, the 3rd the longest, 2-3 in the anterior 

 rays, which are 24 in the length of the head. Pectoral obtusely pointed, with 

 21 rays, its length 3-15 to 3-25 in that of the body; 7th ray longest, reaching to 

 the vertical from the 3rd anal ray. Ventral inserted below the last quarter of 

 the pectoral-base, the spine short and feeble, 24 in the 2nd and longest ray, 

 which is 4-3 in the length of the body and reaches to the 2nd anal spine. 



Gill-rakers short and slender, 7+16 on the anterior arch, the longest 1-3 

 in the gill-fringes and 8-6 in the length of the head. 



Pale yellowish brown, every scale but especially those above the lateral 

 line so closely crowded with dark brown dots as to give the fish a dark 

 appearance; lower surface of head and abdomen faintly tinged with orange; 

 cheeks and postorbital region dark brown. Dorsal fins blackish; caudal 

 brownish ; anal, pectorals, and ventrals yellow, the former narrowly tipped with 

 white, the latter broadly with lavender. 



Etymology: — Named after Mr. Charles William Hill, Lightkeeper at 

 Cowan Cowan, to whom we are indebted for the specimen. 



Described from two Moreton Bay examples, measuring respectively 112 

 and 87 millim. They were obtained at Cowan Cowan, M.B., and Southport, and 

 the larger example, which has been chosen as the type, was presented by Mr. C. W. 

 Hill, to whom I have great pleasure in dedicating it. Its register number in the 

 Queensland Museum is 1. 14/2165.
