The three examples that I recorded from Jamaica appear to belong 

 to this species. The largest, 4^- inches in length, agrees with the others. 

 It has: Head 3f ; depth 5; D. VIH-I, 31, 1; A. II-I, 27, 1; P. ii, 18; 

 V. I, 5; scales 55 in lateral line to first keeled scute; keeled scutes 37 

 in lateral line. Also three examples from the stomach of a horse mack- 

 erel (Pelamys?) taken at Newport, Rhode Island, by Samuel Powel. 

 The largest of these only measures 4J inches. It has: Head 3|; D. 

 VIII-I, 31, 1; A. II-I, 26, 1; and keeled scutes 38 in lateral line. 

 So far as I am able to judge they agree with the Jamaican examples.

Seriola picturata Bowdich^ is represented by a miserable figure and 

 does not appear certainly identifiable with the form on the Pacific 

 coast of the United States. Caranx cuvieri Lowe^ is also an Atlantic 

 form.
