The White-ruraped Swift is fairly common in Uganda and 

 British East Africa. I have found them nesting iu caves. 

 Two of these specimens were caught on their nests. The 

 clutches consisted of two and three eggs respectively. The 

 eggs are white.

X. — J_ Note on the Emperor Goose (Philacte canagica) and 

 on the Australian Teal (Nettion castaneum). By F. E. 

 Blaauw, M.B.O.U. 



In previous papers I have been able to give accounts of the 

 breeding of different species of Geese, and I am glad to say 

 that I am able to add one rare species to the list. 



Two or three years ago I got a pair of Emperor Geese 

 [Philacte canagica) from North America, and a few months 

 later two pairs more. 



The first year following their arrival the birds did not 

 lay, but iu the spring of 1914 one pair laid six eggs under a 

 bush. The eggs were put under a common hen, and only 

 one chick hatched, which came to maturity and is still alive 

 and well. 



In the spring of 1915 the same pair of birds laid again— 

 a clutch of five eggs this time, which I left to the birds to 

 take care of. The nest Avas made at a good distance from 

 the water, and was a rather well-constructed nest for a 

 Goose to make. 



The eggs, when fresh, were yellowdsh white and of an 

 elongated shape. During incubation the male bird was in 

 constant attendance, and never left the female. 



Incubation lasted twenty-four days, being three days
