Depth 2% to 2% ; head 3 to 314, width 2 to 21/3. Snout 2% to 31/3 

 in head; eye 3^4 to 4%, 1 to 2 in snout, greater than interorbital in 

 young to 1 to ly^ in interorbital with age ; maxillary nearly or quite 

 reaches opposite front eye edge, expansion 1% to 3 in eye, length 

 2% to 314 in head; lips moderately thick, fleshy; teeth fine, conic, 

 in 5 to 7 irregular series with outermost little enlarged ; interorbital 

 314 to 5, broadly convex; hind preopercle edge denticulated. Gill 

 rakers 11 or 12+19 or 20, lanceolate, 2 to 214 in gill filaments, which 

 1% to 1% in eye. 



Scales 77 to 88 in lateral line to caudal base and 10 to 18 more on 

 latter; tubular scales 53 to 58 in lateral line to caudal base and 7 

 to 10 more on latter ; 12 to 16 scales above lateral line, 16 to 22 below, 

 37 to 57 predorsal forward to first third in snout, 18 to 24 in vertical 

 series on cheek. Suprascapula entire. Scales with 4 to 6 basal 

 radiating striae; apical denticles 63 to 66, small points, each with 

 12 to 15 transverse series of basal elements ; circuli fine. 



D. XIII, 18, I, to 20, I, fourth spine 21/8 to 2% in head, first ray 

 21/5 to 334; A. Ill, 6, 1 or 7, 1, third spine 13^ to 3%, second ray I34 

 to 21^; caudal 1 to li/^, slightly emarginate behind, truncate ex- 

 panded ; least depth of caudal peduncle 2I/2 to 2% ; pectoral 1% to 

 12/3; ventral 11/3 to 12/3. 



Back and above dull olive gray generally, little paler below; 6 to 

 8 longitudinal or horizontal slightly paler bands, about 10 or more 

 with age, each much narrower than broad resultant bands, also 

 several as those from eye may be partially subdivided by another 

 incomplete auxiliary, variously not reaching the tail or caudal pe- 

 duncle. Iris dull rosy with dusky. Fins all uniformly dull brownish. 



Red Sea, Arabia, Mozambique, Mauritius, Madagascar, Singapore, 

 East Indies, Philippines, China. Some of my examples differ from 

 Bleeker's figures as the latter do- not show the longitudinal bands 

 with darker narrow bordering bands. On the cheek, however, the 

 young show but two horizontal gray bands. Some of my largest 

 examples differ from Bleeker's figure of Plectorhynchus celebicus 

 as there are 13 horizontal pale lines, his figure showing half as many.
