 will not see this publication are the late E. Ashby, E. C. S. Baker,

My personal field experience with Chrysococcyx, although limited 

 to three of the four species that occur in Africa, formed my original 

 basic interest in this group and played a contributing role in the 

 present study. This field experience was made possible by grants from 

 the National Research Council, the American Philosophical Society, 

 the John Simon Guggenheim Memorial Foundation, and the Smith- 

 sonian Institution. 



Permission to reproduce a map (fig. 4) from Fundamentals oj 

 Ornithology by van Tyne and Berger was granted by the publishers, 

 John Wiley & Sons. 



The colored plates of the plumages of the glossy cuckoos were pre- 

 pared for this publication by Evelina R. Templeton, scientific illus- 

 trator of the Los Angeles County Museum of Natural History. 



For her patience with endless changes in the manuscript and for her 

 careful typing of the final copy, my thanks are due my secretary, 

 Myrna L. Patrick.
