teeth, anteriorly ; the dorsal spines increase in length backwards, 

 caudal fin emarginate, with the lobes rounded. Brown, either

 one at the commencement of the lateral line, and one on the back 

 of the tail behind the dorsal fin.

The height of the body is contained twice and three-fourths in 

 the total length. Snout rather shorter than the eye ; the 

 diameter of which is nearly one-third of the length of the head ; 

 interorbital space slightly convex, as broad as the orbit. Prse- 

 orbital naked, half as broad as the orbit, with a shallow notch 

 anteriorly, and a spinous tooth posteriorly ; scales on the cheek 

 in two series ; the lower prseopercular limb with another series of 

 very small scales; proeoperculum strongly serrated. Teeth narrow. 

 The two last dorsal spines rather longer than the middle ones, 

 three-fifths as long as the head ; the soft, dorsal and anal rounded ; 

 caudal fin emarginate, its length being a little more than one- 

 fifth of the total. Brown : caudal fin yellow, the others blackish, 

 sometimes a round, black spot, edged anteriorly with bluish, near 

 the base of the six last dorsal rays ; an indistinct brown dot 

 superiorly in the axil of the pectoral. No spot at the origin of
