ADDENDA 75. CABANGID^E TRACHURUS. 911 



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

 is distinctly different. In 8. pneumatopliorus 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 upper edge of the pectoral ; below this streak 

 the sides and belly are immaculate. In 8. colias (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 streak is obsolete or represented by a line of dots, and the sides below 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.
