Figure 22. — Scarus venosus, USNM 147395. (Drawing by Aime M. Awl.) 



This species is characterized by having 4 median predorsal scales, 

 2 rows of scales on the cheek; ii,12 pectoral rays; white teeth; and a 

 black spot at dorsal base of pectoral fin and 5 vertical dark bars on 

 sides, separated by pale bars about 2 scales wide. The lips do not 

 quite cover the teeth, and the angle between lips varies from 10 to 

 30 degrees. S. rhoduropterus is similar to S. venosus but it has ii,13 

 pectoral rays and no black spot at dorsal edge of pectoral fin base, 

 but base may be somewhat dark brown. 



Scarus venosus has been confused with S. scaber by all recent 

 authors because Bleeker's diagramatic figiu-e of S. pentazona resembles 

 that species in color pattern. S. venosus, with 4 median predorsal 

 scales, cannot be confused with S. scaber, wnich has 5 or 6 median 

 predorsal scales. 



In addition to the types, I have studied 10 lots from the Philippines.
