Dorsal iv, i 8 ; commences midway between point of snout and 

 base of caudal ; spines of 1st dorsal flexible and moderately strong 

 1st spine longest and If- times in length of head ; 5 rows of scales 

 between 1st and 2nd dorsals. Anterior rays of 2nd dorsal nearly 

 !- times height of longest spine of 1st dorsal ; upper margin of fin 

 concave, the posterior rays being slightly produced ; base of fin 

 nearly ^ its height. Pectorals I T \J times length of head, inserted 

 above the middle of the depth of the body and extending to vertical
