All three of these specimens are males. No. 16 is very much 

 darker above than either of the other two, which are about equal 

 to the average bird. Had all three been as dark as this bird, it 

 would certainly have been justifiable to consider it a new sub- 

 species, and this is rather a good example of the danger of making 

 new species or sub-species from a single specimen.

This specimen, with which most unfortunately there is no 

 data, is a very dark bird and has the chin and throat almost con- 

 colourous with the breast, instead of very decidedly paler as is 

 usually the case. The forehead also is very dark and the striae 

 well developed, whilst the whole prevailing tint of the plumage is 

 not only darker but is of a purer grey and less suffused with rusty 

 than any other specimen I have ever seen. There is a good series 

 of this Cuckoo in the British Museum, but this Abor bird is quite 

 different to any of them and should subsequently obtained speci- 

 mens prove to be like it, it will certainly require to be raised to a 

 sub-species. The plumage of Rhopodytes does not vary with the 

 seasons though, of course, newly moulted birds are darker and 

 brighter than birds just about to moult whose feathers have be- 

 come sHghtly bleached.
