2095. POMACANTHUS PARU (Bloch). 

 (PARU; INDIAN FISH; FLATFISH.) 



Head 3; depth 1. 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- 

 cate. Color black; young with 5 yellowish cross bands, the first on the 

 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, 

 and the fifth on the caudal peduncle ; the third turns backward above and 

 extends along the outer edge of the dorsal fin to its tip ; the fourth crosses 

 the anal near its middle and extends backward across dorsal in a similar 

 way; base of pectoral orange; caudal rounded, its border not pale; most 

 of the scales edged with yellow. This species is well distinguished from 

 Pomacanthus arcuatus at all ages by the smaller scales and by the presence 

 of 10 dorsal spines instead of 9. The adults of the 2 are also different 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. In both spe-
