PLEUE0NECTIDJ5. 
“ Body strongly compressed, flat, with orie of the 
two sides, which is always tamed upwards, coloured, 
whilst the other is colourless, and only sometimes 
spotted. Both eyes are placed on the coloured side ; 
and although the hones are present on both sides of 
the skull, they are not equally developed or sym- 
metrical. Dorsal and anal fins exceedingly long, 
without divisions. Gills, four ; pseudohranchiae well 
developed. Air-bladder, none. 
“ Carnivorous fishes, living on the sandy bottom 
of the coasts of all the regions; many ascend 
rivers.” 
EHOMBOSOLEA. 
Genus established by Dr, Gunther, with the following character- 
istics : — Eyes on the right side, the lower in advance of the 
upper ; the mouth unsymmetrical, narrower on the right side 
than on the left ; the length of the left maxillary being less 
than one-third of that of the head ; teeth on the blind side only, 
where they are villiform, forming bauds ; no vomerine or pala- 
tine teeth ; most of the dorsal and anal rays branched ; the 
dorsal fin commences on the foremost part of the snout ; only 
one ventral, which is continuous with the anal ; scales very 
small cycloid ; lateral line straight ; gill-openings narrow, the 
gill-membranes being broadly united below the throat ; gill- 
rakers short and conical. 
The following Melbourne fish enters evidently in this genus, 
but cannot be placed in any of the three species described by 
Dr. Gunther. In the sort I describe here, the dorsal extends to 
the end of the snout, but the number of its rays do not agree 
with any of the species mentioned by that author.
