Dorsal spines twelve ; dorsal and anal fins densely scaly. The 

 height of the body is one-half of the total length (without caudal) ; 

 prteorbital elevated, nearly as high as the orbit. Teeth truncated, 

 not notched. Caudal forked, with the lobes pointed. Twenty-six 

 transverse series of scales. Deep purphsh-brown, with a blue spot 

 below the fourth si^ine, and with another below the third and fourth 

 rays ; a third above the first scale of the lateral line ; a transverse 

 linear spot behind the dorsal. A blue line extends from the snout 

 to the front of the orbit ; another blue line on the praeorbital ; sides 

 of the head with some blue dots, (Gill.)

The height of the body is contained twice and a quarter to twice 

 and a half in the total length (without caudal). The snout is shorter 

 than the eye ; the width of the prseorbital, above the angle of the 

 mouth, is one-half of that of the orbit. Teeth narrow, with a second 

 series of stiU narrower ones which are alternate with those of the 

 front series. The dorsal spines increase in length towards behind ; 

 caudal fin emarginate, with the lobes rounded. Ground-colour 

 brownish, or brown, or greenish, or violet-oUve, with the ornamental 

 markings variously disposed : a blue streak along the median line of 

 the nape and of the forehead, a second along the base of the dorsal fin
