Figure 74. — Caranx latus and Caranx sp. ("latus and/or hippos") : Relation of pectoral length to standard length. 



standard length is shown in figure 75 and table 

 16. A line fitted to this regression for specimens 

 from 16.1 to 119 mm. standard length shows a 

 proportional rate of increase for the two variates 

 within this size range (0.36-mm. increase in body 

 depth per 1.0-mm. increase in standard length). 

 The alinement of the coordinate at about 12.7 

 mm. with the coordinates of the "latus and/or 

 hippos" specimens indicates that a faster body- 

 depth growth rate occurs below approximately 

 16 mm. The position of the coordinates of the 

 specimens larger than 119 mm. with respect to 

 the extension of the calculated regression line, 

 suggests that the body-depth growth may con- 

 tinue at the same proportional rate. 



Head. — The regression of head length on stand- 

 ard length is shown in figure 75 and table 16. 

 A line fitted to this regression for specimens from 

 16.1 to 94.0 mm. standard length shows a pro- 

 portional rate of increase for the two variates 

 within this size range (0.32-mm. increase in head 

 length per 1.0-mm. increase in standard length). 



The coordinates of specimens larger than 94 mm. 

 fall along the extension of the calculated regression 

 line, indicating that head growth may continue 

 at the same proportional rate. 



Eye . — The regression of eye diameter on stand- 

 ard length is shown in figure 76 and table 16. A 

 line fitted to this regression for specimens from 

 16.1 to 172 mm. standard length shows a propor- 

 tional rate of increase for the two variates within 

 this size range (0.09-mm. increase in eye diameter 

 per 1.0-mm. increase in standard length). The 

 position of the coordinates of the "latus and/or 

 hippos" specimens suggests that a faster eye 

 growth prevails below 15 or 20 mm. 



Snout. — The regression of snout length on 

 standard length is shown in figure 76 and table 

 16. A line fitted to this regression for specimens 

 from 16.1 to 172 mm. standard length shows a 

 proportional rate of increase for the two variates 

 within this size range (0.09-mm. increase in 

 snout length per 1.0-mm. increase in standard 

 length).
