44 MESSRS. ROBINSON AND KLOSS ON 



From Gallinula cldoropus orlentalis, Horsf., Trans. Linn. Soc. 

 xiii, 1821, p. 195 (Java), iiihabitng Java, Sumatra, Borneo, and found 

 as a breeding bird in the southern half of the Malay Peninsula, it is 

 distinguished by the smaller frontal shield and by the brown mantle 

 and wing coverts, which are pure grey in tlie Malayan bird. 



There are no actual records of any kind from S. W. or Penin- 

 sular Siam, but the race is certain to be found there. Gallinula 

 cliloroims orlentalis will probably also be found in the Patani Province.

Gairdner's record is the only one for the genus in the vicinity 

 of the area now being dealt with. It is just possible that his 

 identification is correct, and that the bird he obtained was really 

 P. polioceplialus, which differs from the present form in having the 

 mantle bluish green, not blackish, with, at most, an oily green wash. 

 The distinctness of the present subspecies from the typical Javan 

 form, P. calvus, is open to strong doubt ; it only differs in having 

 the head ashy grey in the majority of birds, while in the majority of 

 Javan and Sumatran specimens the head is dark : this, however, as 

 Sharpe points out (Cat. Birds Brit. Mus. xxiii, 1894, p. 201) may 

 be largely due to the effects of wear. 



We have examined two birds from the vicinity of Chiengmai 

 in Mr. Williamson's collection, which are certainly P. jpoliocephalus, 

 another from Chainat, C. Siam, which is probably echvardsi though 

 there is a wash of greenish on the secondaries and mantles. Another
