Horsfield^s GoshaAvk occurs in the extreme south of Tenasserim, where 
it will probably be found to be not uncommon. 
It is met with in China^ Cochin China, the Malay peninsula and the 
islands as far as New Guinea. 
A. cuculoides, an allied species found in China, may possibly visit Burmah 
at times ; it has the under wing-coverts pure white.
