[The Blue-naped Coly is fairly common. I took one nest 

 in an orange-tree in Khartum ; it was flat and made of sticks 

 covered with cotton, and contained two eggs, which were 

 white with irregular brown blotches. — R. M. H.]

Dr. Sharpe (c/. Hand-1. Birds, ii. p. 82) has resuscitated 

 S. nigricans Salvad., which Mr. Hartert considers synonymous 

 with S. climacurus. The series collected by Mr. Hawker 

 clearly shews that the former is merely a dark form of 



t Breeding.
