PLATE VII 



Fig. 17 (top). Central, diabasic plains of southeastern Cuiacjao. These 

 grassy, rolling plains are practically without niolluscan life. 



Fig. 18. To the leeward of Seroe Papaja, southeastern Curacjao. This 

 is an example of the protected borders of the central plains, where the 

 reddish residue in the soil indicates the recent erosion of the limestone 

 cap (compare Cb6 and CblO). A bit of the Hato ridge (Cll) is shown 

 at the extreme left of the background. 



Fig. 19. Valley between Seroes Palomba and Bieutoe (CblTa), north- 

 western Curasao. This is one of the richer valleys of the Christoflfel com- 

 plex. An epiphyte (Tillandsia) is growing on the brush near the center 

 of the picture. It will be noted that much of the vegetation is leafless, 

 as is usual during the dry season.
