FISHERY BULLETIN: VOL. 82, NO. 4 



Geographic variation. — Morphometric data from 

 two populations of S. brasiliensis were compared 

 by ANCOVA: Central America (n = 9-11) and 

 Brazil (n = 39-44). Null hypotheses that the 2 

 sets of regressions are coincident were accepted 

 for 24 of 26 regressions. The two populations were 

 different in Sn-P 2 and 2D-C. Comparison of mer- 

 istic characters for central and northern South 

 America versus Brazil did not reveal any differ- 

 ences (Collette et al. 1978:tables 1-3). 



Material examined. —Total 146 (89-710 mm FL).
