184 cucuLnxs: CHBYSOCOCCYX 



naturalist who has observed the nesting habits of this cuckoo. He 

 says: " In December, 1891, I watched one of these birds for 

 several hours, and finally saw her fly into a thornbush close to a 

 picnic party. On going to the bush I found a nest of Andropadus 

 importunus containing two eggs with the usual markings of grey 

 and brown, together with a single large white cuckoo's egg slightly 

 incubated, while the others were fresh, I have noticed that both 

 this and the former species (Cuculus solitarius) seem to return to 

 the same neighbourhood every year." 



Genus II. CHRYSOCOCCYX. 



Type. 

 Chrysococcyx, Boie, Isis, 1827, p. 977 C. cupreus.

 the longest (third) primary only exceeding the secondaries by about 

 one-third the total length of the wing; tarsus thickly feathered
