BIRDS OF ETHIOPIA AND KENYA COLONY 



423 



Zedlitz ^® writes that northern birds have somewhat larger bills 

 than southern ones, but I do not find this to be the case in the series 

 examined. 



The postjuvenal molt of this hornbill is incomplete, the rectrices 

 and remiges being unaffected. 



The birds collected in northern Kenya Colony during July and 

 August are all in worn plumage but have not commenced to molt.
