another host has been recorded from the Cuckoo. Cuckoos 

 are rarely parasitized, but when you find a Cuckoo that is, 

 it generally has a fair supply, and these parasites are Cuckoo- 

 parasites, We have no evidence of Swift-parasites being 

 found upon Sparrows. 



Mr. Iredale has discussed one or two points, and I may 

 say with regard to the earlier of those groups, A and B^ 

 I had not a great deal of material on which to base my 

 conclusions. Mr. Iredale said it was rarely that one Petrel 

 bred by itself. That is certainly so, but by taking the 

 parasites of species of Petrel from various localities, it is 

 possible to sort out those parasites which are intrinsic and 

 those it has acquired from other species breeding in the 

 same locality. Wherever it is, we occasionally find the 

 parasites of other Petrels upon it. Mr. Buxton has made 

 a comment on the fact of parasites walking out about the 

 head and beak of the bird. That is one of the remarkable 

 things about Mallophaga. The genera have specialised 

 habitats on the body of the bird. As soon as a bird becomes 

 too sick to attend to its toilet, then the Mallophaga 

 increase.
