nest of Campophaga liartlaubi, together with a young bird 

 belonging to the host. The egg turned out to be addled ; but 

 that it did belong to this Cuckoo was evidenced by the fact 

 that a Coccystes jacobinus had been seen to visit the nest.

In December 1897 1 saw one of these birds leave the nest 

 of a Coly {Colius erythromelon). The nest contained three 

 eggs of the host (white with a few pinky scratches), together 

 Avith one egg of the Cuckoo (pure white) .

In November 1896 I found an egg of this Cuckoo in the 

 nest of a "Cape Robin" [Cossi/pha caffra), together with 

 two eggs of the latter bird. 



In the same month I found a young Cuckoo of this species 

 in the nest of a Rock-Thrush [Monticola mpestris) (see 

 fig. 2, p. 25). The nest, which was placed on a ledge of 

 a krantz or cliff, had been extended on either side with a 

 packing of loose moss, so as to prevent the young Cuckoo 

 from upsetting it. One broken egg of the Rock-Thrush lay 

 on the ground below the nest. We waited an hour for the 

 foster-parents, who had flown off on our first approach, to 

 return, but they did not do so, although an adult Cuckoo 

 (C. solitarius) flew past. 



In December 1897 I saw a pair of Caj^e Robins [Cossypha 

 caffra) flying in attendance on a young Cuculus sulitarius ; 

 they were much more demonstrative than is their usual 

 habit with their own young. Tiie two flew before us for over 

 a mile along a water-cut, M'hile the old Cuckoo kept calling 

 out. 



On November the 9th, 1897, I found a nest of Cossyp/ia 

 caffra in a neighbouring garden, containing two of the usual 

 pmky-cream eggs, one of which had been deposited only that 

 morning. This nest Avas only about six inches distant from 

 another, where presumably the same parents had hatched a 

 brood in September. On revisiting the nest next day I
