PLATE IV 



Fig. S (top). Eastern escarpment of Seroe Canashito (A4), Ariiba. 

 In the foreground are the slopes of the older rocks, planted with aloes, 

 and with a Cereus fence at the base. In the center are the high, exca- 

 vated, ancient limestone cliffs of Seroe Canashito, with the separated 

 blocks that are characteristic of these escarpments. The cacti on the 

 summit are 15 to 20 feet in height. 



Fig. 9 (middle). North towards Kibra di Montague (B3b), Bonaire. 

 Another view, taken from the same locality as the next. One of the 

 better wooded valleys in the limestone. 



Fig. 10 (lowest). Southeastern escarpment of Montague (B3a), 

 Bonaire. These low, broken cliffs of the older limestone are rather well 

 wooded. This and figure 8 are quite representative of the main escarp- 

 ments of the western limestone rims on all of the islands.
