The specimen marked [533], which is an adult, differs in coloration from those usually 
observed at Zanzibar. The prevailing colour of the body is bluish green — each scale, 
excepting those on helly, having a pale-blue crescent, beyond which is a greenish 
margin ; those on the upper part of the body are darkest. Forehead purple, with 
green lines radiating from the eyes, and similarly coloured spots between them. The 
middle of the operculum and part of the prseoperculum red, with waved blue lines. 
Snout green. Dorsal brownish, with a green basal, a red marginal, and a blue intra- 
marginal line ; between the green and blue lines on the spinous portion is a single 
series of blue spots ; there are several series on the soft portion. Anal similarly 
coloured ; caudal marbled with blue, green, and red ; pectorals pale green ; ventrals 
white, marked with blue and red.
