Differences among the six adult Nemadactylus macropterus sam- 

 pling sites in the estimated concentrations (means and standard 

 errors) of the six elements detected by EPMA (Ca, Na, Sr, K, S, 

 and CI), based on point 2 only and on the mean of points 2-6 inclu- 

 sive for each individual examined. Concentrations are reported in 

 units of ppm by weight for all elements other than Ca, which is 

 reported as percent by weight. The two Victorian samples were pooled 

 for this comparison. Site labels are defined in Figure 1 and Table 1.
