14. Chrysococcyx plagosus (Lath.). 



Three specimens, all exactly alike, and answering to the de- 

 scription of C. plagosus in Gould's ' Handbook to the Birds of 

 Australia/ having a broad bill, and only a very faint ti-ace of a 

 single rufous bar on the second tail-feathers. The New Zealand 

 Golden Cuckoo (C. lucidus) has the broad bill of C. plagosus, and 

 the second tail-feathers with several well-marked bars of rufous ; 

 but none of the feathers has a rufous base. This form does not 

 appear to have been noticed elsewhere as yet, although it is cer- 

 tainly migratory with us. It is very remarkable that C. plagosus 

 should be found both in Australia and the Chatham Islands while 

 it is absent from New Zealand, which lies between them. In the 

 Chatham Islands this bird is also migratory. 



Is it not possible that all the individuals of the species C. lucidus 

 leave Australia to breed in New Zealand? so that this species does 

 not spread in Australia ; and the limited number which are suf- 

 ficient to stock New Zealand would scarcely be noticed when 

 spread over Australia. In this way C. lucidus, although in- 

 habiting Australia, would be just as much isolated as if it re- 

 mained altogether in New Zealand, and any variation would not 

 be transmitted by interbreeding to Austrahan individuals.
