REVIEW OF THE PARROTFISHES 91 



and anal fins narrowly edged with dark green ; a series of blue or green 

 spots, one between each ray, basally on dorsal and anal fins, centers of 

 these fins orange; dorsal edge of pectoral dark blue-green, remainder 

 light yellowish brown; outer caudal rays darker brown (blue when 

 alive) center of that fin dark brown; tip of chin orange; blue-green 

 color streaks on head as shown in figure 17 (see p. 44), Life colors 

 from a Kodachrome supplied by Loren P. Woods, Chicago Natural 

 History Musueum. 



This species may be distinguished by 6 median predorsal scales; 

 3 rows of scales on the cheek, with 2 scales in the ventral row; ii,13 

 pectoral rays; together with its generally dark brownish coloration and, 

 sometimes, 4 dark bars on upper sides. From S. californiensis and S. 

 azureus it differs in having a more slender form, the greatest depth 

 varying from 2.5 to 3.0 instead of 2.3 to 2.5; head 1.0 to 1.25 in depth, 

 shorter than or nearly equal to greatest depth. 



Although I tentatively recognize S. noyesi as distinct, it is ex- 

 ceedingly close to S. ghobban, of the Central-West Pacific and Indian 

 Ocean, and may be the same. A study of freshly caught specimens is 

 needed to clarify its status. 



In addition to the paratype I have studied several other specimens 

 from the Galapagos Islands.

This species is very close to S. azureus, differing only in color pattern. 

 The general background coloration is reddish brown, centers of scales 

 dorsally brownish green, edges paler; dorsal and anal fins narrowly 

 edged with green, then remainder of fins marked with short green bars 

 parallel with rays, no green streak basally as in azureus; caudal fin 

 with green streaks corresponding with rays; distal edge of pelvic green; 

 pectoral fin with dorsal edge green and a green submarginal bar dis- 

 tally; chin pale; dark green marks on head as illustrated in figure 18 

 (see p. 45). 



This is a deep-bodied species; depth 2.3 to 2.5; head 1.2 to 1.3 in 

 greatest depth; 6 median predorsal scales, 3 rows of scales on the cheek, 

 with 2 or 3 scales in the ventral (thkd) row; pectoral rays ii, 12 or ii, 13 ; 

 teeth white; and caudal fin deeply forked on large adults.
