Osteology 



Osteological characters proved to be useful in 

 determining relationships among the 18 species 

 of Scomberomorus and between this genus and 

 its presumed closest relatives, Acanthocybium 

 and Grammatorcynus. The osteological portion of 

 the paper is divided into five sections: skull, axial 

 skeleton, dorsal and anal fins, pectoral girdle, 

 and pelvic girdle. Osteological terminology gen- 

 erally follows Gibbs and Collette (1967) and Col- 

 lette and Chao (1975). Organization within sec- 

 tions is similar to that of Collette and Chao (1975) 



and the two earlier papers of most importance to 

 the osteology of Scomberomorus: Mago Leccia 

 (1958) on three western Atlantic species (caualla, 

 maculatus, and regalis) and Devaraj (1977) on 

 four Indian species (commerson, guttatus, ko- 

 reanus, and lineolatus) and Acanthocybium. 



SKULL 



Description of the skull is presented in two 

 sections: neurocranium (Figs. 11-19) and bran- 

 chiocranium.
