Dorsal XIII, 13; anal II, 12; scales in lateral series 27; with 

 tubules 19 ; between lateral line and origin of dorsal 4 ; between 

 lateral line and vent 11. 



Body ovate-oblong, compressed, elevated, its depth 2 in 

 length; head 2.8; depth of caudal peduncle 5.8. The convex 

 interorbital 3.2 in length of head, as wide as length of snout; 

 diameter of eye and maxillary equal in length, each contained 

 3.5 in head. Jaws even, cleft of mouth almost horizontal; 

 teeth compressed in a single series, with the incisors emarginate. 

 Gill rakers 8 -f 15 on first arch. Width of orbital ring above 

 angle of mouth less than half diameter of eye. 



Scales absent on orbitals, chin, and edges of preopercle ; snout 

 and anterior portion of interorbital space also naked. Fourth, 

 fifth, and sixth dorsal spines highest, equal to second anal 

 spine. Soft dorsal produced into a point; anal rounded; caudal 

 unequally forked, the upper lobe longer; tip of pectoral above 

 anus ; ventral fin reaching origin of anal, its first ray filamentous. 



Ground color in alcohol lemon yellow, with seven blackish 

 crossbands which are wider than the interspaces between them ; 

 the first, rather indistinct, across head ; the second across neck ; 

 the third, fourth, and fifth below spinous dorsal; the sixth 

 from anterior dorsal rays to base of anal; the last one around 

 caudal peduncle. Spinous dorsal with a dark margin; base of 

 caudal with a conspicuous black spot superiorly. 



The above account is that of an example, 58 millimeters long, 

 collected at Paraoir, Balaoan, La Union. I have examined also 

 four others, 28 to 82 millimeters in length, from Guam, which 

 are in the Bureau of Science collection. 



This species has been reported previously from the "Philip- 

 pine Islands" by Giinther; from Bulan, Sorsogon, by Evermann 

 and Scale ; and from Zamboanga, Mindanao, by Scale and Bean. 

 Outside of the Philippines, it occurs throughout the Red Sea
