S. wieneri 



Eight gill rakers on lower limb, and a 

 few coarse tubercles on upper limb, of 

 first arch. 



Seven oblique rows of scales between 

 lateral line and first dorsal spine. 



Ventral fin inserted fully an eye's diam- 

 eter behind base of pectoral, some- 

 what longer than pectoral, 2.15 in 

 head. 



Caudal deeply lunate, the lobes of 

 about equal length. 



Dorsal spines quite low, rather strong, 

 the longest one 4.1 in head. 



Longest soft ray of dorsal much longer 

 than the longest spine. 



Second anal spine small, firmly bound 

 to first soft ray, its point not free, 

 about a third the length of first soft 

 ray, 7.5 in head. 



Eye 13.0 in head. 



Margin of preopercle with two rather 

 broad indentations, the spines at 

 angle covered by membrane. 



Brown stripes along the rows of scales 

 discontinued abruptly on about lower 

 fourth of side and in advance of verti- 

 cal from second anal spine, but ex- 

 tending to base of anal behind this 

 hne. 



S. starksi 



Ten gill rakers on lower limb, and 3 or 4 

 on upper limb, of first arch. 



Nine or ten oblique rows of scales be- 

 tween lateral line and first dorsal 

 spine. 



Ventral fin inserted close behind base of 

 pectoral, of about same length as 

 pectoral, 2.0 in head. 



Caudal deeply lunate, the upper lobe 

 notablj' longer than the lower. 



Dorsal spines longer, quite slender, the 

 longest 2.5 to 2.9 in head. 



Longest soft ray of dorsal rather shorter 

 than longest spine. 



Second anal spine larger, less firmly 

 bound to first soft ray, its point free, 

 about half length of first soft ray, 5.75 

 to 6.0 in head. 



Eye 9.75 to 10.0 in head. 



Margin of preopercle evenly rounded, 

 without indentations, the spines at 

 angle sharp, distinctly projecting be- 

 yond the membrane. 



Brown stripes along rows of scales be- 

 coming gradually indistinct on lower 

 part of side, not extending on side to 

 base of anal. 



Although the Mission did not furnish specimens of S. starksi, as 

 already stated, it is listed in the report (1943, p. 283) among the com- 

 mercially important fishes, and therein it is stated, "It is reported to 

 attain a weight of over 50 pounds." Landings are listed from several 

 ports in northern and middle Peru.
