Our specimens agree with Bleeker's figure as regards general habit, and consequently 

 may be identical with his fish. 



The width of the bony part of the interorbital space is not much less than the extent 

 of the snout, and is conspicuously concave. The specimens (from Aden and Zanzibar) 

 agree perfectly as regards the spiny nature of the skin ; the spines extend superiorly 

 from the interorbital space to the middle of the distance between the dorsal and caudal, 

 and inferiorly from the chin to the anal. They are rather prominent and densely 

 crowded on the belly, and less prominent on the back and sides. 



The chief difference between our specimens and those described by other authors is the 

 coloration. In the former the upper parts are brown, with white ocelli ; belly uniform 

 yellowish white ; sides with or without several longitudinal white interrupted bands, 

 but always with four irregular black blotches — one at some distance below the eye, the
