Misidentification 



Thynnus brachypterus Cuvier (1829) was based on 

 illustrations by Rondelet (1554) and Duhamel du 

 Monceau (1769). Collette (1966) has indicated that 

 this name is a synonym of Sarda sarda (Bloch) . Al- 

 though Cuvier (in Cuvier and Valenciennes, 1831) 

 based his later description of T. brachypterus on speci- 

 mens, four of which are T. thynnus and one Euthyn- 

 nus alletteratus, this can not be regarded as the origi- 

 nal description, and these specimens are not types. 



Types of Nominal Species 



Scomber thynnus Linnaeus, 1758. No type speci- 

 mens. Original description not diagnostic, but 

 based on Artedi (1738a, p. 31), who stated: "Longi- 

 tude 7 pedum circiter." This could only refer to 

 the bluefin tuna. 



Thynnus mediterrancus Risso, 1826. Substitute 

 name for Scomber thynnus Linnaeus, 1758, and tak- 

 ing the same type. 



Thynnus vulgaris Cuvier in Cuvier and Valen- 

 ciennes, 1831 . Sub-stitute name for Scomber thynnus 

 Linnaeus, 1758, and taking the same type. 



Thynnus secundodorsalis Storer, 1867. No type 

 specimens. Original description based on two speci- 

 mens, 8 feet, 6 inches (1,590 mm.) and 9 feet, 3 

 inches (1,820 mm.) total length. The pectorals 

 "about one seventh of length of fish," the size and 

 the locality (Mass.) unquestionably assign this 

 nominal species to the synonymy of Thunnus thyn- 

 nus thynnus.
