Figure 7. — Comparison of the regression lines for the relation of body depth at pelvic to standard length for five species 



of Caranx. 



one below the lateral line on the posterior portion 

 of the peduncle, converging toward the lateral line, 

 and ending on the fleshy part of the caudal — is not 

 produced until about 60 to 75 mm. standard 

 length in the five common species examined 

 (present on the smallest dentex of 78.5 mm.). 

 This character is more pronounced at sizes larger 

 than 100 mm. The paired caudal keels form at 

 about 30 mm. on crysos, ruber, and bartholomaei 

 (at slightly larger sizes in latus and hippos) on the 



fleshy part of the caudal fin posterior to the caudal 

 base. 



Pectoral. — 1-18 to 23. C. crysos averages the 

 greatest number of rays; ruber, the least. 



A composite graph of the regression lines for 

 pectoral length on standard length of the five 

 common species is shown in figure 6. These 

 species can be adequately compared between 16.1 

 mm. and 125 mm. standard length. Within this 

 size range all species have an inflection followed
