The greatest hight of the body is at the origin of the first 

 dorsal; it is contained eight and three sevenths times in the total 

 length. The hight at the origin of ventrals is contained nine 

 and one half times in total length. The hight of head at the 

 first gill opening is a little greater than that of body at the ven- 

 tral origin, ^while its hight at the angle of the mouth is a little 

 less than one eleventh of the total length. The least hight of 

 the tail equals the hight of the anal, and is contained 25 times 

 in total length. 



The head is somewhat depressed in front, with moderately 

 sharp snout, which is nearly twice as long as the distance of its 

 tip from the mouth. The distance from snout to last gill open- 

 ing is contained five times in total length. The distance from 

 snout to first gill opening, measured horizontally, equals twice 

 the hight of body at origin of second dorsal. The distance 

 between the first and last gill openings equals nearly twice the 

 length of the eye. The hight of the first gill opening is about 

 equal to the distance between the angle of the mouth and the 

 spiracle. The hight of the head at angle of mouth is contained 

 11 times and at the first gill opening nine times in total length. 

 The length of the snout equals one half the body hight at origin 

 of first dorsal. The distance of mouth from snout, measured 

 on the axis of the fish, equals one third width of mouth. The 

 distance from snout to angle of mouth, obliquely taken, equals 

 one fourth the distance from snout to last gill opening. The' 

 distance between ey<^ and spiracle equals that from mouth to 

 nostril. The distance from angle of mouth to spiracle is about 

 equal to hight of first gill opening. The spiracle is moderately
