Depth S%; head 3. Snout 25^; eye 5^; maxillary 4, not quite 

 reaching front nostril; interorbital little elevated. Scales 27 in 

 lateral line, 2 above, 8 below, about 10 (?) predorsal. D. VIII, 14, 

 eighth spine 3^5 in head, first ray 3. A. Ill, 12, third spine 53^, first 

 ray 3}4- Caudal 1^^ in head, slightly double concave behind. 

 Least depth of caudal peduncle 2}/^; pectoral 1%; ventral 2. Head 

 with 2 red bands; first from snout to eye then toward pectoral 

 origin; second from chin to lower eye edge, then down over side of 

 chest below pectoral base. Body with 2 red parallel bands, upper 

 from suprascapula to upper caudal rays, median from pectoral axil 

 to caudal base medianly, and both united by close set red bars over 

 trunk and front of tail. Black blotch at front of spinous dorsal and 

 outer portion of pectoral black. Small blue spot at pectoral origin 

 with red bar across base of fin. Fins otherwise uniform. Length, 

 112 to 117 mm. (Bleeker.) 



Cape of Good Hope, East Indies, Philippines, Riu Kiu, Melanesia, 

 Polynesia, Fannings. There is little doubt but that Scarus quin- 

 quevittatus Bennett is intended for the present species. It only dif- 

 fers in the dark median longitudinal band on the dorsals, likely the 

 artist's exaggeration. This name will then have priority over the 

 usual Julis giintheri of Bleeker. 



Halichoeres iris is described with life colors greenish above, bluish 

 below, with 7 purplish oblique bands over back down on sides me- 

 dianly. Top of head and nuchal region purple, with 3 wide rosy- 

 purple lateral bands, 1 from posterior of eye to posterior margin of 

 opercle near base of pectoral, 1 from lower posterior portion of orbit 

 to lower posterior margin of opercles, 1 from lower anterior margin 

 of orbit to behind angle of mouth.
