Head 3i; depth IJ. D. X, 29 or 30; A. Ill, 23 or 24; scales about 65 in a 

 median series, 85 to 90 in the series above the lateral line ; caudal fin trun-

 snout, the second across the opercle, the third across the body under the 

 tip of the pectoral fin, the fourth across the posterior third of the body,

 of 10 dorsal spines instead of 9. The adults of the 2 are also dift'erent in 

 color. In Pomacanthus arcuatus each scale has a whitish crescent; there 

 is a white stripe from eye to nostril; the caudal and dorsal without pale 

 edge, and there is no pale area behind preopercular spine. lu both spe-
