As pointed out by STRESEMANN (Nov. Zool. Vol. 20. 1913 p. 322) the Crow 
Pheasants inhabiting Siam, the Indo Burmese countries south to the Northern Malay 
Peninsula, ought to be separated under a subspecific name on account of their smaller 
size and somewhat differing colour. 
This species is rather common over the whole country in shrub- or secondary jungles 
and in such localities its loud call is generally heard.

This race of the Large Green-billed Malkoha was rather common in shrub- and se- 
condary jungles over the whole of Siam. Sometimes it was also observed in evergreen 
forests. In such kind of vegetation I once found a nest containing two newly hatched 
youngs and one egg. The nest was situated almost at the top of a tree quite close to the 
stem and very difficult to see from a distance. 
Even in the Siamese Malaya this species occurs and it has also been recorded by 
Rosinson & Kuoss from the Northern portions of the Malay Peninsula. 
The allied Rhopodytes diardi Luss. is also recorded from Northern Siam (conf. 
Barton. Journal Siam, Nat. Hist. Soc. Vol. I. Nr. 2 p. 107), but though I made a careful 
lookout for that species I never observed it in any part of the country visited by the Ex- 
pedition. If the bird recorded by Barron is not wrongly identified it adds a considerable 
area of distribution to that species which is a southern form. Davison who spent several 
years in Tenasserim and collected assidously remarks that »it is entirely confined to 
the southernmost district of the province and meets R. tristis about Mergui and replaces 
it southwards of this place».
