This report, covering the nonpasserine birds collected by the Childs 

 Frick African Expedition, was undertaken, the material studied, and 

 the report finished while I was a member of the department of biol- 

 ogy in Amherst College and an associate in African ornithology in 

 the Museum of Comparative Zoology at Harvar(i University. The 

 actual study of material and literature was done at the latter institu- 

 tion, where Messrs. Outram Bangs and James Lee Peters very kindly 

 put the collections under their care at my disposal. Dr. Thomas 

 Barbour has greatly facilitated the present study by generously pur- 

 chasing for the Museum of Comparative Zoology many species of 

 East African birds not otherwise represented, and which proved 

 most useful in the revisionary work involved in the examination of 

 the present material. 



To Dr. Alexander Wetmore and Dr. Charles W. Richmond, of the 

 United States National Museum, I am indebted for many favors; to 

 the former for the privilege of studying the splendid series collected 

 by the Frick Expedition, to the latter for the care and trouble he has 

 taken in packing and shipping to Cambridge all the birds listed 

 in the present report, for loans of special material needed for com- 

 parative purposes, and for much assistance in reading proofs of this 

 report. 



No one who has done any extensive systematic work will fail to 

 realize that for its successful completion large collections and exten- 

 sive specialized library facilities are indispensable. It was therefore 

 out of the question to pursue investigations of this sort in Amherst 

 College, and, realizing this condition, my former colleagues there. Dr. 

 Otto C. Glaser and Dr. Harold H. Plough, very kindly permitted me 

 to arrange my teaching duties so that I was free almost every week
