REVIEW OF THE PARROTFISHES 53 



caudal peduncle 160. Length of longest dorsal spine 160; of soft 

 dorsal ray 146; of anal spine 75; of soft anal ray 127; of pectoral 243; 

 of pelvic 215; of caudal 288. 



The following counts were recorded: Dorsal IX, 10; anal 111,8 (this 

 unusual count occasionally occurs in specimens of this genus) ; pectoral 

 ii,12-ii,12; pelvics 1,5-1,5; branched caudal rays 6+5; median pre- 

 dorsal scales 4; 3 rows of scales on the cheek with 1 scale in third 

 (ventral) row. 



The lips do not quite cover the white teeth, the angle between the 

 lips is about 25 degrees, and the inner lip has a narrow free fold across 

 front of the upper lip; two canines are present at the corner of the 

 mouth, that on the lower jaw is stronger than that on the upper jaw. 



In alcohol, anterior part of body dark brownish, posterior half 

 light brownish, abruptly paler behind a line extending from base of 

 dorsal spine VIII to anus ; dorsal edge of pectoral base with a blackish 

 spot; a pale band from snout and corner of mouth past lower edge of 

 eye to angle of opercle; edge of lower lip dusky, then posteriorly two 

 other dusky bands on under side of head. 



A Philippine Albatross color drawdng of the holotype, made from 

 the live specimen, shows the anterior part of body dark brownish 

 green, posterior half of body light green; middle of caudal peduncle 

 yellow; pectoral fin yellow with a blue base; caudal fin orange vnih 

 blue edges, and with blue and green marks; anal fin blue, with a 

 brownish red band basally; dorsal fin blue edged, then submarginaUy 

 with an orange streak, middle of fin green, basally with brownish red 

 blotches ; a green streak from snout past lower edge of eye to angle of 

 opercle ; teeth white ; edge of lower lip blue, then posteriorly an orange 

 band followed by a blue band, then orange, with a blue blotch; 

 pelvic fins orange with blue edges. 



John Randall, University of Hawaii, photographed in color a speci- 

 men of this species at Arno Atoll but the specimen was lost. The 

 color is the same as on the Albatross drawing, except that the anterior 

 part of the body is brownish purple and the base of the pectoral fin 

 is bluish black. 



This species may be recognized from its close relatives by the key. 

 It is characterized by having 4 median predorsal scales; 3 rows of 

 scales on the cheek, with 1 scale in the ventral (third) row; ii,12 

 pectoral rays; and white teeth. The dark anterior half of the body 

 contrasts with the pale posterior half; the side of the caudal peduncle 

 is yellow, as is the pectoral fin, the latter has a black spot at its dorsal 

 basal edge and a blue base.

In addition to the holotype, only a photograph, a drawing, and 

 illustrations in the Hterature have been studied.
