Diagnosis Auxis rochei rochei has fewer corselet 

 scales, 5-24 (usually 6-19, Table 1), under the sec- 

 ond dorsal-fin origin than A. rochei eudorax, 14-30 

 (usually 20-25). 



Description Gill rakers 39-49, usually 41-47 in the 

 Mediterranean, Gulf of Guinea, and Indo- West Pa- 

 cific (Table 2); 39^6, usually 40-44 in the western 

 Atlantic. The western Atlantic population has a nar- 

 rower corselet (usually 6-9 scales wide under the 

 second dorsal-fin origin compared with 8-19 in the 

 eastern Atlantic and Indo-Pacific, Table 1) but ap- 

 pears best referred to as A. r. rochei. Corselet width 

 under second dorsal-fin origin (Fig. 3) 2.0-10.0 mm, 

 usually 3.0-7.0 mm, except in the western Atlantic 

 where corselet width is only 1.0-4.0 mm, usually 1.5— 

 3.5 mm. Dorsal scaleless area fails to reach pectoral- 

 fin tip(Fig. 1) by up to 23.0 mm (Fig. 5); usually 3.0- 

 17.0 mm in the Mediterranean, Gulf of Guinea, and 

 Indo-West Pacific; may extend a little anterior to the 

 pectoral-fin tip in the western Atlantic (Fig. 8). 



Types 



Scomber rochei Risso, 1810. Holotype MNHN 

 A.5808 (395 mm FL), Mediterranean, Nice. Pectoral 

 fin 50.1 mm; anterior extent of dorsal scaleless area 

 extends 10.3 mm posterior to tip of pectoral fin; width 

 of corselet under second dorsal-fin origin 3.7 mm; 12 

 scales in corselet under second dorsal-fin origin; gill 

 rakers 9 + 33 = 42. Fig. 13A. 



Auxis vulgaris Cuvier, 1831. Lectotype MNHN 

 A.5808, herein selected. This specimen is also the 

 holotype of A. rochei; thus A. vulgaris is an objec- 

 tive synonym of A. rochei. 



Auxis thynnoides Bleeker, 1855. Holotype RMNH 

 6049 (260 mm FL), Indonesia, Ternate; C.F Goldman. 

 Pectoral fin broken, 27.2+ mm; dorsal scaleless area 

 extends does not reach tip of pectoral fin; 5 scales in 

 corselet under second dorsal-fin origin; gill rakers 

 11 + 36 = 47. Photograph of holotype in Boeseman 

 (1964, pi. 3, fig. 9). 



Auxis Ramsayi Castelnau, 1879. Holotype MNHN 

 A. 1241 (290 mm FL), Australia, New South Wales, 

 Sydney. Pectoral fin 34.7 mm; anterior extent of dor- 

 sal scaleless area 12.7 mm posterior to tip of pecto- 

 ral fin; width of corselet under second dorsal-fin ori- 

 gin 5.7 mm; 15 scales in corselet under second dor- 

 sal-fin origin; gill rakers 10 + 33 = 43. Fig. 13B. 



Material examined 261 specimens (58.7-443 mm 

 FL) from 102 collections.
