purple base, except on the extremity of the tail, which is entirely green. Snout 
purple ; upper lip with a red margin next the jaw ; throat blue : a red margin to lower 
lip, extending as far as the cheek-scales; a red spot at the symphysis of the lower jaw, 
and a red line from the first scale of the lower cheek-series across throat and down 
margin of interoperculum; one or two red spots on interoperculum. Dorsal green, 
with a yellow median band and a blue margin. Anal green, with a purple base and a 
blue margin. Pectorals green ; a red streak along the second ray. Caudal green, with 
a blue margin. — Length 10 inches. 
Var. h [522]. Jaws rosy, with two conical teeth at the angle of the upper jaw. The 
caudal lobes slightly produced. Colour purple brown, each scale with a darker basal 
membrane, except on the extremity of the tail, which, like var. «, is lighter than the

and marginal line. Anal and ventral darker. Pectorals yellow, with a brown base. —

Jaws grey, very strong, distinctly denticulated on the margins, and with one or two 
conical teeth at the posterior angle of the upper jaw. Lips rather narrow, double only

contains five scales, the prseopercular limb being entirely naked. Caudal slightly 
convex. Dorsal spines subequal. Fifteen pectoral rays. 
The naked portions of the head deep blue, the general colour of the rest of the 
head and body black: the body-scales are irregularly marked with opaque yellow-
