ICHTHYOLOGY 
Height of body three times and one-third in total length of 
the fish, or three times without the caudal ; head twice and 
six-eighths in the same dimension ; eye four times and a half 
in the length of the head. 
The upper profile is very convex, with the head attenuated ; 
the lower profile almost straight ; the teeth are in small number, 
far apart one from the other ; there is on the upper jaw, and 
in front a rather strong canine, on each side ; the lower jaw is 
longer than the upper one ; its teeth are larger behind than 
in front ; the head is generally naked, but there are four series 
of scales on the sides of the cheeks, and more on their lower 
part j the prseoperculum is finely serrated backwards, but not 
at its lower edge ; the notch is considerable ; the operculum 
terminates by an angular flat spine ; it has eight series of 
scales on its greatest breadth. 
The body is compressed ; the lateral line runs regularly to the 
base of the caudal ; it extends over about sixty-six transverse 
lines of scales, without counting a few more very indistinct 
ones at the base of the caudal • the transverse series number 
about thirty-four ; the lateral line passing over the tenth. 
The dorsal fin is formed of eleven spines, of which the first 
is the shortest, the second nearly twice as long, the fourth, 
fifth, and sixth the longest, and about equal ; the others 
grow shorter as they go backwards ; the soft dorsal is formed 
of fifteen rays ; the caudal is strongly emarginated, of seventeen 
rays, which, except the central ones, are covered with minute 
scales. Anal with three spines ; the first short ; the second 
twice and a-half as long ; the third is nearly as long as the 
second, but much more slender ; the soft part is formed of 
eight rays, and this part, as is also the case with the similar 
portion of the dorsal, has its base covered with minute scales ; 
the pectorals are rather large, with their spine long and slender ; 
the pectorals extends much further back than the ventrals ; 
they are very pointed and formed of seventeen rays. 
The general colour is of a beautiful red pink, with the head 
of a lighter tinge ; a sulphur yellow stripe runs from the 
anterior margin of the eye towards the mouth ; the same
