emarginated, slightly bilobed, formed of nineteen long rays and 
of three or four small ones on each side. The external rays are 
about one-third longer than the centre ones. Anal short, con- 
tained nearly nine times in the total length, caudal included, and 
formed of two spines, of which the first is small, and the second 
five times longer ; it is compressed, very strongly serrated on its 
inner side, and of six rays ; the first of these is longer than the 
rays, and the last considerably shorter. The ventrals are formed 
of one rather long and slender spine, and of nine rays ; the pec- 
torals are inserted very low, much below the angle of the mouth, 
and have nineteen rays ; they are a little shorter than the dis- 
tance from the anterior edge of the orbit to the end of tbe oper- 
culum ; the ventrals have one long, slender spine, and seven 
rays rather longer than the spine, which is neither notched nor 
serrated. 
The colour of the first specimen was of a light gilt green on 
the upper and lateral parts, and of a silvery white below ; the 
base of the scales very brilliant ; the eye silvery ; the throat and 
anterior part of the belly very brilliant and iridescent ; the dorsal, 
caudal, and anal were of a greyish green ; the ventrals white ; 
the pectorals white at their base, and green in the remainder of 
their length. 
The natatorial bladder is large, formed of two parts — the 
first about two-thirds as long as the other, but broader ; it is 
rather bilobed in front ; the second portion is oblong, and 
rounded at its extremity. 
The second specimen was entirely of a beautiful red colour, 
with golden tinges on the sides of the head and body, very much 
like G^prinus Auratus.

This second specimen — the one of a red colour — has a lar 
more irregular form than the first, the back, behind the head, 
being very gibbous, and the lower profile still more inflated. Its 
lengtli is eleven inches, and its height five and a-quarter.
