Euthynnus alletteratus (Rafinesque) 



Galapagos Islands, Albemarle Island, Tagus Channel, July 25, 

 1938. U.S.N.M. No. 107056. 1 specimen. 



First taken on the cruise in the Galapagos at three or more stops 

 including Tagus Channel, and Sulivan Bay, James Island ; the heaviest 

 one caught weighed about 17 pounds. Although known from the 

 warmer waters of the Pacific and Atlantic, these represent a first 

 Galapagos record. There may be some question as to the identity ol 

 this species. Anatomically it seems to differ little from Euthynnus 

 lineatus (Kishinouye), over which it may take precedence as the 

 earlier named species. The color and color pattern of the two are 

 very 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 Walford 

 in color in his "Marine Game Fishes" (pi. s ^. fig. b). Also the 

 color note given by Hildebrand in Meek and Hildebrand. "The 

 Marine Fishes of Panama," p. 311, I9 2 3> appears to fit our specimen.
