Types. — Scomberomorus plurilineatus Fourma- 

 noir 1966 was based on a 740 mm specimen 

 collected near Nossi-Be, Madagascar, in 1965. The 

 type was supposed to be transferred from the 

 O.R.S.T.O.M. collections to the MNHN collec- 

 tion but apparently was inadvertently discarded 

 (M.-L. Bauchot and P. Fourmanoir 7 ). 



Description. — Lateral line gradually descending 

 to midline on caudal peduncle. Intestine with two 

 folds and three limbs (Fig. 31). Spines in first 

 dorsal fin 15-17, usually 15 or 16 (Table 9); second 

 dorsal fin rays 19-21, usually 20 (Table 10); dorsal 

 finlets 8-10, usually 9 (Table 10); anal fin rays 19- 

 22, usually 20 or 21 (Table 11); anal finlets 7-10, 

 usually 8 or 9 (Table 11); pectoral fin rays 21-26, 

 usually 22 or 23 (Table 12). Precaudal vertebrae 19 

 or 20, usually 20 (Table 6); caudal vertebrae 25-27, 

 usually 26 (Table 7); total vertebrae 45 or 46, 

 usually 46 (Table 8). Gill rakers on first arch (2- 

 3) + (9-13) =12-15, usually 2 + (10-11)= 12-13 (Ta- 

 ble 5). Morphometric characters given in Table 24.

 beromorus plurilineatus. FL = fork length, HL = head 

 length. 



Diagnosis. — The only species of Scomberomorus 

 that has a pattern of short wavy lines and spots on 

 its sides (Fig. 63). Other species have straight 

 lines, spots, blotches, or bars on the side or are 

 plain. Posterior end of maxilla greatly expanded 

 as in S. lineolatus and S. semifasciatus.

Size. — Maximum size 120 cm FL, South African 

 angling record 10.0 kg, sexual maturity attained 

 at about 80 cm FL (van der Elst 1981). 



Color pattern. — Williams (1960) published a good 

 description of fresh specimens from Zanzibar. 

 Head blue-grey above, silvery white below, except 

 for lower jaw tip, preorbital area and maxillary 

 groove dusky to black. Pupil of eye black, rest 

 silvery. Body iridescent blue-grey above lateral
