The snout is rather produced, short, conical, somewhat longer than 

 the diameter of the eye ; praeoperculum very indistinctly serrated ; 

 the soft portions of the anal and dorsal fins very elevated, with the 

 angle rounded. The ocular band extends to the base of the ventrals, 

 another concentric brown band over the snout, and a tliird across the 

 operculum and the side of the belly. Sides of the body with alter- 

 nating hghter and darker stripes, angularly bent, with the angle 

 pointing forwards. The soft dorsal and anal, the caudal, and the 

 tail between those fins, blackish ; the fins with a narrow lighter mar- 

 gin ; a whitish line across the root of the caudal and the base of the 

 anal, forming the continuation of the margin of the dorsal fin.

The skeleton is exceedingly similar to that of Chcetodon vagabundus, 

 and differs fromit by a more elevated operculum, its Avidth being 2| in 

 its height. The interhsemals of the anal spines are anchylosed together.
