This species is characterized by having 4 median predorsal scales, 

 usually 3 rows of scales on the cheek, at least on one side, the ventral 

 (third) row consisting of one scale, or it may be lacking; and ii,12 

 pectoral rays. The dorsal edge of the pectoral fin base has a small 

 black spot, usually present in preserved specimens. This species 

 may be mistaken for S. aeruginosus because it, too, when preserved, 

 has the 2 or 3 light streaks, one on each scale row of the abdomen. 

 Among the various species studied it is the only one in which the 

 third, or ventral, row of scales on the cheek is present or absent. 

 The general background coloration is brownish, with the median fins 

 pale. When alive, the caudal and dorsal fins are yellowish and the 

 caudal peduncle may also be yellowish. 



In addition to the types I have studied numerous specimens in 92 

 lots from the Philippines and vicinity.
