[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 [of. Hand-1. Birds, ii. p. 82) has resuscitated 
S. nigricans Salvad., which Mr. Rartert considers synonymous 
with S. climacurus. The series collected by Mr. Hawker 
clearly shews that the former is merely a dark form of 
t Breeding.
