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 belly, 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 praeoperculum 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.
