Specific Characters. — Shape fusiform ; depth of the body at the origin of the dorsal 

 fin contained about four times in the entire length ; fins Large with numerous ra)s, 

 dorsal and anal triangular and high in front ; fin-rays dehcately longitudinally striated, 

 save in some cases the proximal parts of those of the lower lobe of the caudal ; their 

 joints variable in length, but tending to become very short in large individuals, and in 

 some varieties ; pectorals having their principal rays jointed up to their origins; fulcra 

 minute. The scales are finely serrated on the posterior margin and delicately striato- 

 punctate, but there is a great variety in the relative extent of the striation and puncta- 

 tion. As a rule the most anterior scales are entirely striated ; those of the middle of
