Body naked, much compressed, band-like, tapering gradually back- 

 ward fromtbe vent; caudal peduncle very slender, the caudal fin small,

 cle half greatest depth of body, its least depth one-third interorbital 

 width, which is 4 in head. Snout 2^ in head; maxillary not reaching,

Page 424. After Scomber pneumatoiihorus read : 



667 (ft). S. colias Gmelin. — "Spanish Macl'enl" of Europe. 



Our Atlantic and Pacific representatives {grex Mitch. ; diego Ayres) 

 of 8. pneumatophorus seem to be identical, but both differ in some 

 respects from the European "Spanish Mackerel." S. colias Gmel. 

 has the head longer, 3^ to 3f in length (instead of 4); its spinous
