The height of the body is two-sevenths to two-ninths of the 

 total length, the length of the head one-fourth. Caudal fin 

 rounded ; dorsal spines rather slender ; the first ventral ray 

 produced. A bluish-black yellow edged ocellus between the fifth 

 and seventh dorsal spines ; corners of the caudal fin broadly 

 yellow. Brownish-green, with eight or nine dark cross-bands on 

 the back ; pectoral fin with a bluish-black spot in the axil ; dorsal 

 and anal fins with one or two series of large, round, yellow spots 

 along the basal half.

My specimens have none of the bands on the back, mentioned 

 above, nor is there any trace of yellow spots on the dorsal and 

 anal fins, so that I may be wrong in ascribing them to this species, 

 but the colours of all these Labroid fishes are so completely 

 effaced by spirits, that no dependence can be placed on marking 

 or colouring.
