This species is characterized by having 5 or 6 median predorsal 

 scales; 3 rows of scales on the cheek, with 1 to 3 scales in the ventral 

 row; usually ii,12 pectoral rays; whitish teeth; and a plain brownish or 

 grayish background coloration with usually 3 pale streaks, one on each 

 scale row of belly. There is no black spot at base of pectoral fin. 



The lips almost cover the whitish or olive teeth in some specimens 

 whereas in others, notably in those 130 mm. and longer, they are 

 considerably exposed, the inner lip joins the outer lip at the symphysis; 

 from to 2 canines on each jaw may occur at the corner of the mouth, 

 these usually appearing at a length of 150 mm. or longer; distal margin 

 of caudal fin rounded in young, becoming truncate, the outer rays 

 becoming a little elongate at lengths greater than 100 mm. 



In alcohol the background coloration is plain brownish or reddish 

 brown; at lengths of about 150 mm. and longer, 3 or 4 light streaks, 

 one on each scale row, occur on belly from breast to origin of anal fin, 

 sometimes one or more of these light streaks continue as far as the 

 caudal peduncle. 



In live specimens, the background coloration is plain reddish 

 brown; fins tinged with red; dorsal and anal fins darker along edges; 

 iris yellow; and teeth white. 



This species has been confused with several others, especially 

 sordidus and dubius both of which have only 4 median predorsal 

 scales. The 3 or 4 pale streaks on the belly caused Weber and de 

 Beaufort to confuse this species with S. dubius Bennett. Actually
