The yellow-biUed Cuckoo of Java, comparatively with other species of this 

 Genus, has a broad bill, a highly arched covering to the nares, and a greatly elon- 

 gated exterior hind toe. The wings are also proportionally long and slender : in its 

 other characters it agrees with the rest of the Genus. Among the Javan species it 

 most nearly resembles the Cuculus flavus ; it has a similar form and general distribu- 

 tion of colour, but it is very rarely met with, and never allows itself to be approached. 

 I have procured two individuals only, which agree in size and characters : I have 

 not had an opportunity of observing it in a state of liberty.
