44 EINAR LÖNNBERG, BIRDS. 



Columbidae. 



Vinago calva salvadorii Dubois. 



Rchw. I, p. 396. 



In the trees growing along Roirn river I found these Green Pigeons rather coninion 

 3 4 1911 and shot without difficulty three specimens with a small specimen gun. The 

 cere was orange yellow, the iris sky-blue with an outer ring of lilac colour, which, however, 

 disappeared with the death of the bird. Feet red. 



The birds werein moult in the beginning of April. 



Reichenow has recently distinguished with the above name the Green Fruit-Pigeon 

 of the Central African lake district and the present specimens belong evidently to the 

 same race. Dearbornin's Vinago calva nudirostris* from Nairobi represents probably 

 this race as well. 



Columbia guinea (L.). 



Rchw. I, p. 401. 



When our Expedition had arrived to Guaso Nyiri we camped at the förd on the Mar- 

 sabit road, and I found then this beautiful pigeon very plentiful in the doum-palms along 

 the river. Some ti me låter when we were camping at the dry river -bed at Njoro I also saw 

 and shot several of these pigeons in the döum-palms at the locality mentioned. It was 

 also found at the water-place Thera in the dry thornbush country north of Guaso Nyiri. 



Carlo von Erlanger 2 expresses his doubts concerning Blanford's observation 

 of this pigeon perching in trees. It may therefore be emphasized that I saw numbers of 

 these pigeons perching in the doum-palms at the localities mentioned. In the crowns of 

 the palms they were also heard cooing and seen courting the females. Specimens shot 

 about the middle of February had their genital organs strongly swelled. Three out of 

 four specimens shot at Njoro had the crop so intensely filled with food that it bursted when 

 the birds fell and struck the ground. 



Length of wing from 216 to 222 mm. Iris straw yellow, or yellow, sometimes light 

 red. Naked parts round the eye cherry red. 



Columba arquatrix T em. 



Rchw. I, p. 403. 



Oberholser 3 hasexamined two specimens of this pigeon from Kilimanjaro and ar- 

 rived to the conclusion, that his specimens »differ so much from the true Columba arqua- 

 trix of southern Africa that they represent without apparent doubt a Avell characterized 

 geographical race to which Bonaparte's name arguatricula is probably applicable >>. The 

 northern form is said to »be distinguished by decidedly larger size as well as by smaller, 

 much less numerous spöts on the lower surface, and these confined chiefly to the upper
