with age ; younger birds have paler central rectrices, older specimens 

 darker ones. According to Neumann and Sclater and Mackworth- 

 Praed, erlangeri has a distinct tinge of rusty brown on the under- 

 parts, which are not pure gray. This the present series fails to 

 confirm, as some individuals have, and others have not, this rusty 

 tinge.

A Juvenal bird, collected on May 25 at Bodessa, when about 10 days 

 out of the nest, resembles adults generally, but differs in having the 

 crown patch deep fuscous instead of black, in having the entire super- 

 ciliaries buffy, and in having the upper wing coverts broadly edged 

 with rufous-buff, lighter than the rufous on the remiges. 



The majority of the present series are in rather worn plumage, 

 while a few, taken in April and May, are in molt. The freshest 

 plumages are those of birds taken in December and January.
