REVIEW OF THE PARROTFISHES 65 



upper jaw 1 + 1, 1+2 or 2+2, and on lower jaw 1 + 1 or 2+2; in 

 figure 9 (p. 37) are sketched the important color marks, chief of which 

 are the green edges of lips, the dark line submarginally along distal 

 edge of caudal fin, the broad pale edge (green when alive) of anal fin, 

 and the dorsal fin set off submarginally by a dark line. 



The lips nearly cover the whitish teeth in both jaws; the inner lip 

 joins the outer much closer to the symphj^sis than to the corner of the 

 mouth; well developed or strong canines occur at the corner of the 

 mouth, their number varies in the upper jaw from 1 to 3 and in the 

 lower jaw from to 2, usually there are 1 or 2 ; the caudal fin is slightly 

 concave at all sizes, with the outer rays a little elongated in the larger 

 adults. This species increases in depth with age. 



Various authors have not recognized this species and have confused 

 it with such species as sordidus and taeniurus. 



Pseudoscarus bataviensis (Bleeker, loc. cit., pi. 12, fig. 3) appears 

 to be a drawing with the color marks oiforsteri, except that the caudal 

 fin is more like that of S. taeniurus. Probably the artist had both 

 species. 



In alcohol, specimens in the green color phase, at standard lengths 

 of 117 to 190 mm., have the background coloration light grayish to 

 greenish; edges of both upper and lower lips green, the band on snout

extending to ventral part of eye, and that on lower lip to corner of 

 mouth, these not separted by a narrow pale area; 2 other green bars 

 on under side of head separated by pale interspaces; usually 3 short 

 green bands behind eye separated by pale interspaces; anterior edges 

 of pelvic fins margined with greenish; dorsal and ventral edges of 

 caudal fin margined with green; caudal fin may have 8 other green 

 streaks on membranes,' parallel^with the rays; distal margin of caudal
