FAMILY SCARIDAE — SCHULTZ 245 



snout; three blue spots on mid ventral line in front of pelvics; dorsal 

 and anal fins, each with 3 color streaks (basally green, center orange, 

 distally blue). The young of S.formosus have dark and light streaks 

 on the sides of the body. In the adult the forehead is enlarged 

 giving to the head a strongly convex dorsal contour. 



SCARUS SCHLEGELI (Bleeker) 



Pseudoscarus schlegeli Bleeker, Versl. Akad. Wet. Amsterdam, vol. 12, p. 242, 

 1861 (type locality, Celebes); Atlas ichthyologique . . ., vol. 1, p. 48, pi. 12, 

 fig. 2, 1862 (Celebes). 



SPECIMENS STUDIED 

 Bikini Atoll: 3 stations, 5 specimens, 146 to 200 mm. in standard length; 1 lot, 

 Univ. Washington, 1 specimen, 205 mm. 



Rongerik Atoll: 2 stations, 3 specimens, 180 to 255 mm. 



Remarks. — This species has been confused with Scarus mutahiliSj S. 

 caudofasciatus, and S. zonularis, all of which represent a single species. 

 It is easily distinguished from these by having only 4 median predorsal 

 scales and only 2 rows of scales on the cheek, whereas all others that 

 have been confused with species with vertical dark bars have 5 or 6 

 median predorsal scales and 3 rows of scales on the cheek, except 

 S. venosus Bleeker and S. rhoduropterus Bleeker, but the latter lacks 

 a dark spot at base of upper pectoral rays and the lips are separated 

 by an angle greater than 65 degrees. S. venosus differs in having 5 

 dark vertical bars. S. schlegeli, may be recognized by its coloration: 

 A black spot at the base of the upper pectoral fin ray, under soft 

 dorsal fin 2 broad dark bars separated by a light bar, and pale colora- 

 tion anterior to the first dark bar.

Remarks. — S. taeniurus belongs in the group of parrotfishes with 2 

 rows of scales on its cheek, 4 median scales in front of dorsal origin, 

 and the pectoral rays are usually ii,12, with occasional exceptions. It 

 is characterized by a rounded caudal fin in the young, becoming at 

 most truncate in adults, with the distal margin marked with a fine
