C O n t a cl O r a is low-lying, its highest j)oint being hardly 

 more than 25 m above the sea-level, and devoid of fresh wa- 

 ter. The greatest length is from east to west 2,2 km, its width 

 1,2 km. The island was totally blasted and showed but a very 

 poor animal-life. 



Chapera is a very hilly island, covered with a rich 

 vegetation. It is not at all cultivated as Saboga, but shows a 

 more pronoimced tropical character, especially more abmidant 

 in palms than the latter. The greatest extent of the island is 

 from east to west 2,2 km, the smallest in the direction north 

 to south 1,7 km. The hills reach a height of slightly more 

 than 100 m. 



P a j a r o s (or M o g o - M o g o ) has not so rich a vegeta- 

 tion as Chapera and is more hilly than this island. The greatest 

 length and width of Pajaros scarcely reach 2 km. 



B o 1 a n o s and B a v a r e n a are small and low-lying is- 

 lands but wooded. 



C a s a y a was at the ti me of Dr. Bovallius visit on the 

 west-side covered by dense primeval forests, and on the east- 

 side well-cultivated and richly populated. There were great 

 cultivations of cocoas and banana-trees. 



Mina is low-lying and devoid of fresh water but very 

 richly wooded by cocoas. 



B a y o n e t a is characterized by a very varied nature, the 

 rocks at the coast being remarkably polished by the waves. 

 Landward they, however, form mountain ridges covered by 

 forests and separated by narrow valleys or mangrove-fens, 

 the latter being remainders of silted gulfs. 



The bird-life was eminently rich. 



V i v e r o s is covered by dense tropical forests. The in- 

 habitants — at Dr. Bovallius visit more than 50 house- 

 holds — cultivate yams, maize, bananas, cacao and some sugar- 

 cane. They have plenty of swine and poultry and also some 

 cattle. 



Sennora and Sennorita, two rocky holms, descend- 

 ing abruptly into the sea. Only the former was visited. 



Pedro Gonzalez is, according to its size, the third 

 of the Pearl Islands, the greatest length being 7 km and the 

 width more than 5 km. The interiör of the inland is covered 

 with a very rich vegetation. Bovallius states that the island 

 is inhabited by about 100 people.
