Lower jaw projecting beyond the upper. Eye very small. Scales 

 of moderate size. Vent below the gill-opening. Anal fin com- 

 mencing behind the point of the pectoral. Young examples gene- 

 rally with more or less numerous obUque brown bars, which disap- 

 pear with age or are broken up in spots ; sometimes of a uniform 

 dark coloration. 



This species varies, not only in coloration, but stiU more in the 

 form of the body and head. The " dorsum canaliculatum " can be 

 observed in very fat examples, and the notch behind the anterior 

 nostril is more distinct in old than in young examples. The number 

 of the teeth cannot be used as a specific character, ,as it varies 

 from 38 to 56 in the lower jaw, and from 26 to 40 in the upper.
