with large pores few in number, axial along upper side of body. 

 Dorsals separated, membranes of spinous fin entire to ends of spines; 

 soft fin nearly or quite high as first dorsal. Anal similar, smaller 

 and opposite, with 2 slender spines, second larger and longer. Caudal 

 moderate, rudimentary rays well developed. Pectoral long, reaches 

 to or little in anal, especially in young, with broad base, simple rays 

 nearly half number of fin rays. Ventral inserted slightly before 

 pectoral origin, fin rather small. 



Apparently differs from Lioscorjnus Giinther in the presence of 

 iDut 2 anal spines, a character not shared by any species of Setarches. 

 Setarches remiger (Gilbert and Cramer) differs further not only in 

 its 3 anal spines, but also the deeper body, more doi*sal spines, and 

 the dorsal fins joined; moreover its pectoral is longer and its scales 

 are very small.
