color dorsally; another pale streak forward from middle of eye to 

 middle of snout. 



The lips do not cover the whitish teeth, the angle between upper 

 and lower lips varies from 25 to 55 degrees; the inner lip joins the outer 

 lip a little closer to the symphj^sis than to the corner of the mouth; 

 canine teeth at corner of mouth vary from to 2 in both jaws, usually 

 1 or 2 in specimens 200 mm. and longer; distal margin of caudal fin 

 strongly concave, outer caudal rays elongate. 



In alcohol, dorsal part of head and body grayish or light brownish, 

 ventrally paler; head abruptly paler below a line from middle of snout 

 past ventral margin of eye to upper pectoral base; scales with few to 

 several small spots that may preserve as pale or dusky spots or may be 

 entirely absent in long-preserved specimens; dorsal part of pectoral 

 base blackish, this black may cover the entire base in some specimens; 

 pectoral fin with pale dorsal edge, below which is a wide brownish 

 streak, the lower half of pectoral fin pale; anal fin with dusky edge 

 covering outer third of rays, pale centrally, with a dusky blotch at 

 base of each ray; dorsal fin narrowly edged with dusky, rest of fin pale 

 except for a dusky blotch on membrane between each ray and at base 

 of each ray; a pale streak from midfront of eye forward to front of 

 snout; other narrow pale streaks radiating from eye; usually a conspic- 

 uous dark ocellate spot at base of third or fourth dorsal spine, except 

 on large adults. 



Live specimens in the green color phase have the background 

 coloration generally bluish green; center of scales green on postero- 

 ventral sides, those anterodorsally with a few to several small green 

 spots or oblong spots, remainder of scales light gray or whitish; 

 lower half of head below eye light green; pelvic and caudal fins green- 

 ish; both narrow streaks from snout to eye are green separated by 

 light gray; pectoral fin green except for the grayish pink streak below 

 upper rays of that fin, pectoral base purplish black. 



Calloydon vermiculatus Fowler and Bean, resembles this species in 

 coloration rather closely except the ocellate black dorsal spot is lacking, 

 the pectoral base is not blackish, and the caudal fin lacks the lunate 

 shaped reddish blotch. 



I have studied numerous specimens in lots from the following 

 localities: Fanning Island, 2 lots; Samoa, 1; Marshalls, 4; Mauritius, 



Hot.
