take precedence as the earlier named species. The color and 
color pattern of the two is quite different and if not due to 
variation will serve for ready recognition of the two forms 
in the field. One specimen from Tagus Channel, Albemarle 
Island, July 25, 1938, was saved. The color and pattern of 
the markings on the back of this fish at first glance appear 
very much like those of the Pacific Mackerel as figured by TTal- 
ford in color in his "Marine Game Fishes" (Plate 37, fig. b). 
Also the color note given by Hildebrand in Meek and Hildebrand, 
"The Marine Fishes of Panama" 1923, (p, 311) appears to fit our 
spe c imen .
