CUCULUS CANORUS? 



I saw a Cuckoo, which I believe to have been of this 

 species, on Aldabra, but I was not able to get it. 



Centropus insularis Iticlgw.

Bill, tarsi, and toes black. 



I obtained an adult female and a barred young female of 

 this- species on Aldabra ; it is larger than C. assumptionis, 

 especially as regards the bill and tail, and is lighter maroon 

 on the wings. I did not see many individuals of this bird on 

 Aldabra, but it is doubtless more numerous than I imagined 

 at the time, as it is easily overlooked, especially on such a 

 large island, and is very retiring in its habits, though by no 

 means shy. 



Corvus scapulatus Daudin.

One immature male. 



This Crow is not common on Aldabra ; I met with it only 

 in one place, near some Casuarina-trees on the shore. 



Alectrcenas minor Berl.

 p. 493 (Aldabra) ; Sharpe, Hand-1. Birds, vol. i. p. 62. 



Two adult females, one female scarcely adult, and one 

 immature pair. 



The Aldabran " Fruit-Pigeon " is apparently not an 

 abundant species. I saw one near the Settlement, and a 

 few on the further side of the lagoon about thirty miles off; 

 in the latter place they frequented a clump of tall trees close 

 to the Ibis-colony. This bird, unlike the members of the 

 genus met with elsewhere, was very shy, and I had some 

 difficulty in obtaining adult specimens. The young were in 

 moult from the nesting to the adult plumage. In the first 

 plumage they are green above, every feather being edged with
