Centropus sinensis intermedius: Kobinson I p. 93; Robinson II p. 14G; Gyldenstolpe III p. 233. 



$ Koon Tan 5 /ö 1914. L = 480 mm.; W == 196 mm.; T --= 266 mm.; C = 36 mm. — $ Doi Par

 ad.: black, juv.: horn colour. Legs: black. 



As pointed ont by Stresemann (Nov. Zool. Vol. 20. 1913 p. 322) the Crow 

 Pheasants inhabiting »Siarn, the Indo Burmese countries south to the Northern Malay 

 Peninsula, ought to be separated under a snbspecific name on account of their smaller 

 size and somewhat differing colour. 



This species is rather comraon över the whole country in shrnb- or secondary jnngles 

 and in such localities its loud call is generally heard. 



200. Rhopodytes tristis hainanus. Hart. - The Large Green-billed Malkoha.

This race of the Large Green-billed Malkoha was rather common in shrub- and se- 

 condary jungles över the whole of Siarn. 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 

 Robinson & Kloss from the Northern portions of the Malay Peninsula. 



The allied Rhopodytes diardi Less. is also recorded from Northern Siarn (conf. 

 Barton. Journal Siarn, 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 Barton 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 ])lace».
