Color. When alive, of a general rusty brown, or in some specimens golden brown, 

 more strongly marked above the middle of the body by ferruginous spots being densely 

 distributed along the scales ; these spots are more sparse and more distinct below the 

 lateral line ; the body, beneath and in front of the ventral fins, of a blood-red color ; 

 the throat is bluish-white. A bluish-white undulating line runs from the upper jaw 

 just beneath the eye, across the operculum and beneath the opercular membrane to 

 its posterior extremity ; a second line of a similar character arises just above this, and, 

 interrupted by the eye, again commences back of it, and passes over the opercular 

 membrane ; so that the membranous appendage of the operculum, which is broad, 

 rounded posteriorly, and of a uniform black color, is between these lines. Beneath 

 the undulating lines just spoken of are bluish-white blotches irregularly distributed upon 

 the preoperculum, some of them passing downwards towards its lower edge. Pupils 

 black, irides red. The dorsal fin is anteriorly of a dark-brown color ; its posterior 

 membranous portion is red. The ventrals are red at their base and black at ex- 

 tremities. The pectorals are of a yellowish-brown color. The anal is yellowish at 

 its base and fuliginous at its margin. The caudal is of a blood-red color. After death, 

 the body becomes of a bluish-gray color ; the abdomen changes to orange ; the ex- 

 tremities of the ventrals are purple ; and the tail is rust-colored, livid posteriorly. 



Description. Length of head, including the opercular membrane, equal to about one 

 third the length of the body ; - greatest depth of fish, exclusive of the dorsal and 

 anal fins, equal to more than one third the length of the body. The head, between
