 of anal; scales rather large, with slightly flexible ctenoid posterior 

 edges, extending forward nearly to tip of snout, extending on base of 

 second dorsal, not forming a continuous sheath, present on at least 

 basal half of interradial membranes of caudal, also extending slightly 

 on bases of anal and pectoral, 5, 6 full oblique rows between lateral line 

 and first dorsal spine and 6, 7 between it and first ray of second dorsal; 

 dorsal fins contiguous, the spines slender, the fourth one longest, not 

 reaching beyond tips of succeeding spines, 2.7, 2.4 in head; second
