 Gen. Av. ii. p. 9. 



Hab. Malacca, Sumatra (Bp.), Java {Wall.). 



I found tbis species on the mountains of Western Java, at an 

 elevation of 8000 feet. Iris dark ; bill lead-colour ;^ feet red. 

 Three Indian species are allied to these, but are sufficiently 

 distinct, viz., 



(1) T. apicauda, Hodg. ; allied to T. oxyura. 



(2) T. sphenura , Vig. ; allied to T. korthalsi. 



(3) T. phasianellus, Blyth. 



Two other species occur in islands beyond the Archipelago, 

 viz., 



(4) T. formosee, Swinhoe, in the Island of Formosa. 



(5) T. sieholdi, Temm., in Japan.
