One of these two specimens has the centre of the lower sur- 

 face whitish, the other distinctly greyish-brown, and yet they 

 were shot on the same day and on the same spot. It is there- 

 fore probable that this dissimilarity is due to the difference in 

 age, which appears from the fact that the whitish one is a young 

 bird. I think that Reichenow is justified in doubting the 

 genuineness of these two races, and I therefore give B o c a g e ' s 

 name for the Elgon form.

This race was common in the Nairobi regions and in Mom- 

 basa. Both specimens are in full plumage and have the chin of 

 the same reddish brown colour as the head. The steel-blue 

 lustre on the wings and tail-feathers is very pronounced. 



Reichenow (Jouru. f. Orn., 1921, p. 265) expresses the 

 opinion that the three forms of puella cannot be maintained, as, 

 in his opinion, the characters which distinguish them are not 

 constant. 



I have compared the specimens in Stockholm, which L o n n - 

 berg brought home from Nairobi, and found that the striping 

 varies very considerably, and in 3 of the specimens it is finer, 

 in others coarser. It is the same thing in these two specimens 

 of mine.

I met this race for the first time when we camped at an 

 altitude of 8.500 feet a few days' march north-west of Londiani 

 on the road to Eldoret. It was very abundant everywhere in the 

 upland regions and always appeared in flocks on the edges of 

 the forest or on the acacia-plains. In the evenings large flocks 

 could be seen perched on the dead branches in the tops of the 

 trees. 



On one occasion I saw a bird coming out of a little hole 

 in a dead tree-trunk and perched on a branch near by. I shot 

 the bird and it then turned out to be a female of E. senegalensis. 

 Whether the bird had its nest in this hollow tree or not was impossible 

 for me to find out, as it was not possible to climb up the tree.
