The soft dorsal has its rays faintly barred, the posterior half darkest, the margin irregularly 

 blackish. Caudal with much white pigment, the terminal fourth with a series of oblong black blotches, 

 occupying the membranes between the rays. The remainder of the fin has two or three irregfular cross- 

 series of smaller roundish black spots. The anal is white, some of the rays occasionally margined 

 with black. Ventrals white, sometimes black-margined. Pectorals dusky at base, becoming black 

 toward middle of fin; the distal half is occupied by a conspicuous white cross-bar, beyond which is a 

 narrow bar of black. The white cross-bar does not invohe the upper or the lower rays.
