Depth 23/^ to 2K; head 3 to 3,^, width 1^ to 1J4. Snout 3^ to 

 t^ 33^; eye 2 4/^ to 3; maxillary reaches eye, 3 to Sj/g in head; teeth 

 uniserial incisors, end of each slightly notched; interorbital 3 to 33<£, 

 broadly convex; suborbital and preopercle edges entire. Gill rakers 

 4+12, lanceolate. 



Tubes in lateral line 16 or 17, pores in straight section 7 to 9; 3 

 scales above lateral line to spinous dorsal origin, 8 below, 16 pre- 

 dorsal extending forward to nostril; rayed vertical fins densely scaled 

 basally. Scales with 8 or 9 basal radiating striae, edge scalloped; 

 apical denticles 89 to 90, with 2 or 3 series of basal elements trans- 

 versely; circuli very fine. 



D. XII or XIII, 13 to 15, twelfth spine 1 ^ to 1^.^ in head, eighth 

 ray 1}4 to 1}4', A. II, 12 to 14, second spine l}^ to 1%> sixth ray 

 13^ to 1%; least depth of caudal peduncle 2 to 2)4 ', pectoral ly^ 

 to 13^; ventral 1; caudal 3 to 3)4 in combined head and body, 

 emarginate. 



Brown, paler below, each scale with 1 or 2 pearly to azure blue 

 spots. A band of azure blue, sometimes variably waved or expanded, 

 or again incomplete posteriorly, extends to black ocellus at front of 

 soft dorsal or variably on last dorsal spines. Also a second and 

 usually smaller black ocellus at bases of last dorsal rays. Blue band 

 along side of snout, another parallel along suborbitals and third band 

 across chin and cheeks, last often as row of spots besides rather large 

 scattered blue spots on rest of head. Iris with some blue spots or 

 bars. Fins all brown, caudal and pectoral often yellowish and lower 

 edge of anal dusky. Caudal largely dusky. 



Widely distributed in the Indo-Pacific, from the Red Sea and East 

 Africa to the East Indies, tropical Australia, and Oceania. The blue 

 band along the back is a conspicuous marking in this species, usually 

 embracing the interdorsal ocellus. We have no examples showing it 

 extending to two black blotches on the posterior dorsal rays, as 

 shown in Bleeker 's figure. In none of our examples is the inter- 

 dorsal ocellus absent. Often the blue band may be reduced to a 

 narrow inconspicuous line, of variable extent, along the base of the 

 spinous dorsal. Frequently its posterior continuation is simply a row 

 of blue spots.
