be any extant specimens to verify these records; 

 there is one specimen labelled only as "Cape Cod" 

 (MCZ 23929). The known southern limit of the 

 range is Progreso, Yucatan (MCZ 32894); it is 

 replaced by S. brasiliensis from Belize to Rio de 

 Janeiro and by S. regalis in the Bahamas and 

 West Indies. Reports of S. maculatus from the 

 West Indies (except for the north coast of Cuba) 

 are referrable to S. regalis (Erdman 1949), those 

 from the eastern Pacific are based on S. sierra, and 

 those from the eastern Atlantic on S. tritor. 



Geographic variation. — Morphometric characters 

 were compared for two populations of S. macula- 

 tus by ANCOVA (Table 20): Atlantic coast of the 

 United States (n = 18-24) and Gulf of Mexico (n = 

 28-36). Null hypotheses that the 2 sets of regres- 

 sion lines are coincident were accepted for 20 sets 

 of regressions and rejected for 6: Sn-ID, Sn-P 2 , 

 P X L, Snout (fleshy), Snout (bony), and maxilla 

 length. 



There is also a difference in vertebral numbers 

 between the eastern U.S. and Gulf of Mexico 

 populations. The eastern U.S. population usually 

 has 31 caudal and 52 total vertebrae (x 30.4, 51.5), 

 the gulf population has 30 or 31 caudal and 51 or 52 

 total vertebrae (x 30.9, 52.1). 



The Gulf of Mexico and eastern U.S. populations 

 also differ electrophoretically Skow and Chitten- 

 den (1981) found differences in hemoglobin pheno- 

 types between samples from Port Aransas, Tex., 

 and Beaufort, N.C.
