bronze spots on the sides of the body increases with 

 the size of the fish, young specimens (200 mm) 

 have about 30 spots; adults more, 45 spots (422 

 mm), 47 (455), 46 (470), 45 (516), and 58 (530). The 

 spots are arranged in 3 or 4 rows (sometimes in 2 

 rows). The rows are not very well defined but it is 

 possible to recognize them. The spots in S. 

 maculatus are not arranged in rows. 



The first dorsal fin is black in the anterior half 

 (first 7 membranes) and the posterior half is white 

 with the upper edge black. Pectoral fin dusky; 

 pelvic and anal fins white. In young specimens 

 (192-240 mm) (collected from estuarine waters) 

 the caudal and pectoral fins are yellow (in the 

 pectoral fin, yellow over the dusky color) and the 

 whole body and the anal fin are slightly yellow. 



Range. — Atlantic coasts of Central and South 

 America from Belize at least as far south as Lagoa 

 Tramandai, Rio Grande do Sul, Brazil (Figure 3). 

 Not known to overlap with S. maculatus which 

 occurs in the Gulf of Mexico and along the Atlantic 

 coast of the United States. Replaced in the West 

 Indies by S. regalis. 



Material examined. — Inasmuch as there is abun- 

 dant material from Brazil, and because further 

 study might show some differentiation within the 

 range of S. brasiliensis, the type-material is re- 

 stricted to the specimens examined from Brazil.
