Depth 1^ to 1%; head 3}4 to 3^, width 1% to 1^/^. Snout 2}4 

 to 2% in head from snout tip; eye 3}/^ to 5, !}{ to 1% in snout, 1 to 

 1% in interorbital; maxillary reaches nearly half way in snout, nearly 

 to front nostril, 3 to 3% in head; interorbital 2yg to 3j^, broadly con- 

 vex; preopercle spine along inner edge 23^ to 43^. Gill rakers 5 + 13, 

 very short, small points, about 7? of gill filaments, which slightly longer 

 than eye. 



Scales 70 to 75 counted close along and above lateral line to caudal 

 base; tubular scales about 50 to 56; 13 scales above lateral line, 33 

 or 34 below. Scales with 3 to 8 basal radiating striae; apical denticles 

 25 to 45, each with long slender root; circuli fine. 



D. XIII, 21, 1 or 22, i, last spine Ij^ to 2 in total head length, seventh 

 ray 2}^ to 2% in combined head and body; A. Ill, 19, i or 20, i, third 

 spine 1% to 2}/^ in head, fifth ray 2}4 to 2^ in combined head and 

 body; least depth of caudal peduncle 2 to 2}i in head; caudal convex 

 behind, 13^8 to 13^; pectoral 1 to ly^; ventral 23^ to 3% in combined 

 head and body. 



Largely uniform brown, though median area slightly paler. On 

 trunk and tail most of larger scales each with large dark slaty or blu- 

 ish spot. Iris brown. Border of gill-cover narrowly, also preopercle 

 border narrowly and preopercle spine slaty-bluish. Soft vertical fins, 

 intervening region of tail and caudal peduncle all finely dotted with 

 pale brown, dots not invading dark spots; edges of vertical fins also 

 narrowly bluish; in young pale bluish bars are formed vertically from 

 bases of soft dorsal and anal over caudal peduncle and caudal base, 

 also vertical fins with fewer and much larger blue spots. Pectoral 

 brown. Ventral dusky brown and with bluish tinge along front edge. 



Seychelles, East Indies. The adults or old examples have the soft 

 dorsal and anal fins produced in rather long points, so that both
