This species is distinguished in the first place by its stouter, 

 more robust shape and by its larger eye ; the stouter form is 

 evident also in the figure of Orcynus sibi given by Kitahara. 

 The first dorsal in the specimen which I examined had 13 rays ; 

 finlets, 9 dorsal, the first small but not rudimentary, and 9 ventral,

all with distinct yellow colour in the middle and broad black 

 border. Second dorsal and first ventral also with some black at 

 edges, but little or no yellow, not prolonged as in albacora. 

 Pectorals reaching to past the beginning of the second dorsal but 

 not to the beginning of the first ventral ; pointed and triangular, 

 broad at hase. According to Kitahara, the pectoral reaches to 

 the end of the first dorsal or to the origin of the second, and is 

 therefore rather shorter than in my specimen, which was 

 3 ft. 9| ins. in length. Kitahara says it grows in Japan as 

 large as the common tunny, that is, 6 or 7 feet in length : but I 

 do not know whether this is the case at St. Helena. Known to 

 the St. Helena fishermen as the cofFrey.
