Ornithology of the Egyptian Soudan. 211 



The Abyssinian Sun-bird was abundant on the Erkowit 

 Hill in March^ when the males were in full plumage. I 

 never saw them below about 2000 ft., and about half-a-day's 

 march into the more barren Gamilab Hills south of Erkowit 

 they disappeared entirely. 



4. CiNNYRIS ERYTHROCERIUS (HcUgl.) ? 



I saw a few of these Sun-birds at one locality only in the 

 Bahr-el-Ghazal country — between Moyen and Wau. I shot 

 a male in breeding-plumage on January 3rd, but unfortu- 

 nately knocked it to pieces and did not keep it. I did not 

 see the bird agaiu beyond Wau, and on my return journey 

 I was ill with fever at the point where it had occurred before, 

 and was not able to look for it again.

The Acik Scarlet-chested Sun-bird was very common in 

 the ironstone forest-country from Ayum to Chak Chak, from 

 January to the beginning of April. It is one of the most 

 beautiful Sun-birds. that I have ever met with. The Golo 

 natives call it "Cho-cho.^^ Antinori considered it a migrant 

 to this district from the south, arriving in February and 

 leaving again in the middle of April. I left this part of the 

 country just at that time myself, but I think that it is more 

 probably a resident species, easily overlooked in the luxuriant 

 vegetation of the rainy season when out of breeding-plumage.

The Western Violet-backed Sun-bird was fairly common 

 from Wau to Chak Chak and thence towards Dem Zubeir.
