Fig. 12. The relative distribution of the two highest contours of density of S. gazellae, S. marri, S. maxima, S. serratodentata 

 and S. decipiens in 0° (A), 90" E (B) and 80° W (C) (5. serratodentata and S. decipiens are not present in 80° W). The coloured 

 contours should be compared with figs. 3, 5, 7, 8, 10 and 11.
