XXIV. — Further Notes on the Ornithology of the Cape Verde 

 Islands. By Boyd Alexander. 



The following observations are the result of a second visit 

 to the Cape Verde Islands in October 1897. Before giving 

 thera, however, I should like to withdraw two suppositions 

 made in my previous paper {supra, pp. 74-118) : — 



Firstly J that the Kite of the Canary Islands recorded by 

 Mr. Meade-Waldo under the name of Milvus ictinus is 

 probably the Black Kite (pp. 79-80). This is not the case, 

 M. ictinus being the species resident in the Canaries. 



Secondly, the inference that all Desert-Larks lay no more 

 than a single egg (p. 112). This was assumed on the strength 

 of several nests of Desert-Larks, each containing no more 

 than one young bird, having been found in May ; but the 

 dying away of all vegetable growth, and consequently of the 

 insect-life which is usual at that time of the year on the 

 islands, would be sufhcient to account for many eggs of those 

 early- breeding individuals being unfertile. 



Neophron percnopterus. 



From October to the end of January few adult Egyptian 

 Vultures are to be met with around the villages. During 

 that time they have all gone in couples to the highest hills 

 where they breed, and keep away from habitations as much 

 as possible, seldom coming into the valleys unless a goat or 

 cow is slaughtered by the peasants. Then from Februarv
