The measurements of the present series of 7nacrourus are as 

 follows : 



The typical race of the blue-naped coly occurs in the lowlands 

 of Ethiopia, up to 7,000 feet (2,100 meters) in the higher country 

 of the interior. Blanford *^ gives its altitudinal range as from about 

 2,000 feet (600 meters) or even lower to 5,000 or 6,000 feet (1,500 to 

 1,800 meters), "* * * entirely replacing the last species (C'oZm/v? 

 stnatus leucotls) in the tropical, and to a great extent in the sub- 

 tropical zone." Zedlitz *" writes that it is a bird of the lowlands and 

 the Acacia steppes, but he found it really common only in the Barca 

 district. 



Five of the specimens collected are in molting condition, the 

 ecdysis affecting the rectrices in each case. The tail molt is centrip- 

 etal, and does not begin until the new remiges are full grown. None 

 of these birds shows any signs of body molt. 



The breeding season in northeastern Africa according to Erlanger's 

 observations °° is in May. This agrees with what Lynes found in 

 Darfur^^ where the bird is common. He obtained breeding females 

 and newly fledged young in April and May, and found a nest with 

 two eggs at Khartoum on June 5. Von Heuglin's statement that at 

 Khartoum the nesting season occurs during the rainy season, lasting 

 until the end of September, taken together with the above observa- 

 tions, indicates a rather prolonged breeding time — from April to 

 Septem]).>r.
