Length of head 2 '45, greatest height of body (at ventral fin) 

 2-15, height of body at anterior end of base of anal fin 2 -60, 

 length of caudal fin 3*50 in the total length (without caudal). 

 Horizontal diameter of eye 5 '55, vertical diameter 6'50 in the 

 length of the head ; the former 1*90 and the latter 2-20 in the 

 snout, which is 2-95 in the length of the head. Postorbital por- 

 tion of head 1-95 in its total length. Distance from inferior 

 margin of eye to lower profile of head, 2 '35 in the length of the 

 head, and exactly equal to the length of the base of the anal fin. 

 Height of head at occiput 1-20 in the length of the head and 

 2*90 in the total length. Interorbital space highly convex, its 

 width 4-35 in the length of the head. Eye half its diameter 

 distant from the upper profile of the head. Distance between 

 anterior and posterior nostrils equal to half the interorbital 

 width. Anterior nostril small, tubular, and situated in a shallow 

 fossa ; posterior nostril large, ovate, oblique, and about equidis- 

 tant between anterior nostril and nearest part of the border of 

 the eye. Upper profile of head slightly concave ; the centre of 

 the concavity lying in front of the lowest fourth of the eye. 

 Upper jaw longer than lower. Cleft of mouth somewhat oblique, 

 the maxilla reaching to the vertical from the first fifth of the eye. 

 Teeth strongest and most regular immediately above and below 

 the notch, which is deep. Interopercular knob conspicuous.

 7 80 in the total length. 



Teeth : Jaws with an inner band of villiform teeth and an 

 outer irregular row of slightly curved cardiform ones, which are 

 longest and most acute in the anterior portion of the upper jaw. 



Fins: Length of base of dorsal fin (direct from point to 

 point) 1-80, of anal fin 5 '7 5 in the total length ; the latter 3*20 

 in the former. Third and fourth (longest) dorsal spines equal in 

 length, 2-50 in the length of the head, 2'85 in the greatest height* 

 or 1-50 in the longest dorsal ray (seventh), which is 1'65 in the 

 length of the head and 4'05 in the total length. Third (longest) 

 anal spine 3'15 in the length of the head, or twice in the longest
