ADDENDA 75. CARANGIDiE — TRACHURUS. 911 



dorsal is lower, the longest spines not more than half of head; the color 



is distinctly different. In S. pneumatophorus the dark bauds on the 



back are broader than the interspaces, as broad as pupil; these are 



usually confluent below with a narrow dark lateral streak, which runs 



about on the level of the upi^er edge of the pectoral; below this streak 



the sides and belly are immaculate. In ^S'. coUas (specimens from 



Charleston, S. C, and from Genoa) the dark dorsal bands are much 



narrower, not so broad as the interspaces and more wavy ; the lateral 



streak is obsolete or represented by a line of dots, and the sides below 



are marked by numerous irregular, wavy vertical streaks, spots, and 



reticulations, of a dull pearly-gray color, which are usually broader than 



the interspaces; longest D. spine more than ^ head. The fin rays are 



the same in the two species.
