18 ON NEW GENERA AND SPECIES OF FISHES 
as the highest dorsal ray and 24 in the length of the body, 
as also is the pointed caudal fin: pectoral with 18 rays, 
the middle the longest, extending to the vertical from the 
origin of the anal and a little longer than the head : ventral 
reaching to the base of the first soft anal ray, 24 in the length 
of the body. Uniform greenish brown, the upper surface 
and sides of the head with a purplish gloss: all the fins 
blackish, except the pectorals and basal third of the ventrals, 
which are pale yellowish brown. 
The description is taken from a fine example, 172 
millimeters in length, caught at Mud Island, Moreton Bay, 
by Mr. Percy Power, to whom I have great pleasure in 
dedicating this handsome and very distinct species, which 
he kindly presented to the collection of the Amateur 
Fishermen’s Association of Queensland. Cat. No. 224.

conspicuously enlarged series, and the gill-rakers more 
numerous, longer, and slender (pépos, in part; yupvés, 
naked); 
East Coast of Australia. Two species.

of body 33, length of head 2,% in the length of the body. 
Width of head 3 of its depth and 2 of its length. Length of 
snout #, interorbital width ? of the diameter of the eye, 
which is 3} in the head. Maxillary extending less than a 
diameter of the eye behind the eye, its length 3 of that 
of the head, the width of its distal extremity $ of the eye. 
Jaws with broad bands of small subequal curved teeth ; 
one or two teeth on the vomer. Nasal tentacle minute. 
Gill-rakers 26 on the lower branch of the anterior arch, 
the longest # of the snout. Anterior half of the trunk 
naked, the rest of the body covered with minute seales,
