In the form of the body this species resembles 
the preceding one. The chief differences consist in 
the less forward position of the dorsal fin, the greater 
height of the second dorsal and the greater length of 
the head. From these differences we may see, as is 
often the case, that one character may be highly de- 
veloped, while in other respects the species ranks low 
in the scale of the generic development. 
In size it is about equal to the preceding spe- 
cies, the greatest length being given as 8 dm. For 
purposes of comparison between the two species we 
here give, according to Malm’s measurements, the 
following table:
