different in color, coarser in appearance, and has a larger 

 head, mouth, and eye. 



Body rather short and deep, with a thick caudal peduncle ; depth 4% to 

 5 in length ; back wide, not elevated. Head large, 4£ in length, flattish 

 and broad above, the snout rounded but rather long, mouth large, oblique, 

 jaws about equal; eye very large, 2£ to 3 in head. Scales large, dark- 

 edged above. Lateral line somewhat decurved, with 38 scales, marked by 

 a series of black points; 13 large scales in front of dorsal. Dorsal fin 

 just behind the middle of the body, very slightly behind ventrals; pecto- 

 rals not reaching nearly to ventrals. D., I, 9; A., I, 8; teeth, 2, 4-4, 2; 

 snout in males somewhat swollen, and covered with minute tubercles. 



Coloration in life, olivaceous above and quite dark, owing to the broad 

 dark edges of the scales. A jet-black caudal spot, and a band along 

 caudal peduncle, which vanishes into black points along the sides, and re- 

 appears on the opercles, passing around the'snout. 



Two varieties or forms may be appreciated, the one larger, stouter, and 

 with a larger mouth and much larger eye. They seem, however, to shade 

 into each other. They occur together in about equal abundance.
