208 HISTORY OF THE FISHES OF MASSACHUSETTS. 



GENUS LUMPUS, Cuv. 



Two dorsal fins ; the first dorsal fin so enveloped by a -thick and tubercular skin, 

 that, externally, it might be taken for a simple hump of the back ; second dorsal 

 with branched rays, opposite the anal. Body deep and rough, with conical horny 

 tubercles.

Color. All the upper part of the body is of a bluish-slate color ; the sides and 

 abdomen are of a yellowish-green. The immature fish is blue above, and almost 

 entirely white beneath. Lips yellow. 



Description. The body is suborbicular, compressed at its upper part. The entire 

 surface of the fish is covered with an immense number of small stellated tubercles, 

 studding, in the adults, even the rays of all the fins. Three rows of tubercles, much 

 larger than those which are universally distributed over the fish, and terminating at 

 their apices in naked spines, are observed projecting from either side. One row, com- 

 mencing at the upper anterior angle of the eye, curves slightly over the humeral bones, 

 and then passes in nearly a straight line to the tail ; a second row, composed of much 

 larger, wider, and more prominent tubercles, commences just beneath the posterior angle 

 of the operculum, and terminates on the same plane with the extremity of the first 

 row, the tubercles having diminished in size as they approached the tail, as in the 

 first row; a third row, composed of a small number of still larger tubercles, com- 

 mences on a line with the posterior portion of the ventral disk, and terminates just 

 in front of the anal fin, forming the outer boundary of the abdomen. The two t 

 upper rows of tubercles are of the color of the back ; the lower row is colored like
