My best thanks are due to Mr. C. Helluiayr, Dr. E. Hartert, and M. Menegaux 

 for much useful information about the birds of Cayenne. 



In a futnre article I hope to be able to say some more about the geographical 

 distribution of the Cayenne birds, and to give a summary of the literature referring 

 to them.
