78 EINAR LÖNNBERG, BIRDS. 



This Nightjar belongs probably to the true So malifauna, but it has been foimd as 

 far west as at Lake Baringo, and it also extends as far south as to the Kilimanjaro-district 

 like some other members of this fauna. 



Caprimulgus stellatus Blund. Lovat. 



Rchw. II, p. 359. 



On the acacia-steppe near Lekiundu river, just south of Guaso Nyiri in a place partly 

 covered by thornbush I had the pleasure of shooting a male specimen of this pretty Night- 

 jar, which was discovered some years ago near Kassim river in Southern Abyssinia, and 

 thus forms another strong proof for the extension southwards to the Guaso Nyiri district 

 of the northeastern fauna. 



Iris blackish brown. Wing 157 mm. 



Macropterygidae. 



Apus apus (L.). 



Rchw. II, p. 377. 

 Commonly seen at Nairobi and several other places. 



Tachornis parvus myochrous (Rchw.). 



Rchw. II, p. 385. 



This Swift belongs to the steppe-country. I saw it for the first time över the plains 

 at Juja farm. Then as soon as we had descended on our way northward from Meru borna 

 to the acacia-steppe round Luazomela I found it to be common and it remained so as long 

 we were in the low country. 



A young bird with rusty edges to the feathers was shot at Luazomela Va. 



I am uncertain whether the birds seen in the Guaso Nyiri district belong to this 

 subspecies or to T. p. parvus, as I did not shoot any there. 



Hirimdiiiidae. 



Riparia sp. 



Sandmartins were observed at Nairobi, and at Rooruka river, but in places where 

 I was not allowed to shoot, so that I could not ascertain to which species they belonged. 



Chelidon rustica (L.). 



Rchw. II, p. 406. 



Common at many places as Fort Hall, Meru Borna etc. 



A young bird with the crown of the head brown was shot at some little distance 

 from Meru borna the 30 th of Jan.
