ISLAS DE AVES. 



These islands are situated about 30 miles southeast of Bonaire 

 and consist of two groups of low cays called Ave de Sotavento and 

 Ave de Barlovento. The largest island is about 3^ miles long, being 

 fringed in places with mangroves and having a scant growth of grass 

 and low bushes in the interior. Mr. Ferry visited Ave de Barlovento, 

 the eastern group, and remained there two days, January 23 and 24, 

 1909. As far as I am able to learn this island had not previously 

 been visited by a collector.
