Color. The living fish is of a light salmon-color, mottled with irregular olive 

 blotches, darker towards the head. The front and top of the head are of a light brown ; 

 two indistinct oblique bands upon the operculum, one back, the other in front, of the 

 eye, on each side of the head. Body beneath white ; neck flesh-colored. The dorsal 

 fin is almost white, salmon-colored at its edge. The pectorals are of a true salmon- 

 color, lighter at their origin. The ventrals are salmon-colored. The anal fin is flesh- 

 colored at its base, salmon-colored at its edge, with seven distinct white blotches in its 

 length. The dorsal, pectoral, and anal fins are perfectly transparent. 



In the dead specimen the colors are deeper ; the general tint is a yellowish-brown 

 or fawn color, sprinkled with darker patches. The front and top of the head are 

 livid; the gill-covers are lighter, but rather dull. The dorsal and anal fins are 

 greenish tinged with yellow. 



Description. Body very much elongated, tapering to a point, compressed posteriorly. 

 Its entire surface, with the exception of the head, exhibits innumerable minute cup- 

 like depressions. Head large, compressed at its sides, broad and flat above as far as the 

 angle of the eyes, convex at forehead. Cheeks protuberant. Lips exceedingly fleshy ; 

 the upper lip is very large, projecting beyond the lower, and in some individuals even 

 an inch beyond it ; the under lip is less fleshy than the upper, and is suspended at its 

 angles like those of a mastiff". The upper jaw slightly projects beyond the lower.
