Color. While alive, some individuals of this species are of a greenish-yellow color, 

 with four transverse dark-brown bars, which extend from the dorsum to the lower 

 part of the sides ; the anterior of these is nearly as wide at its base as the first 

 dorsal fin at which it commences ; the second is situated at the anterior half of the 

 second dorsal ; the third, which is narrower than the second, is at the posterior half 

 of the second dorsal ; the fourth band crosses the fleshy portion of the tail. In others 

 the general color is of a greenish-brown, the bands are very indistinct and appear 

 rather like large blotches. Abdomen white. The first dorsal is fuliginous, and crossed 

 by distinct dark- brown bands. The second dorsal is crossed by three longitudinal 

 bands of dark brown. The pectorals are of a light-yellow color ; broad when expanded ; 

 the inferior rays are flesh-colored ; these fins are crossed by six dark-brown concentric 

 bands of different widths. The ventrals are yellowish-white ; the intermediate mem- 

 brane clouded by indistinct bands of dark brown. The anal is yellowish, crossed by 

 indistinct dark bands. The caudal is yellowish-white, with five very distinct bands. 

 Pupils bluish ; irides reddish, with a coppery hue when alive. 



Description. Length of head equal to one third the length of body ; its greatest 

 width equal to two thirds its length. Twenty spines are seen upon and about the head, 

 ten on each side ; all these are naked at their extremities. The nasal spines are small 

 and recurved ; the post-orbitar spines are a little longer than the nasals ; they are 

 barely elevated above the top of the head, and point directly backwards ; the occipital 

 spines are erect and slightly recurved ; they are rather stouter than the post-orbitars ;
