44 MESSRS. ROBINSON AND KLOSS ON 



From Gallinula cldoropni^ orlentalis, Horsf., Trans. Linn. Soc. 

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

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

 distinfjuished by the smaller frontal shield and by the brown mantle 

 and wint( coverts, which are pure grey in the 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 

 chloropus orlentalis will proljably 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. 'polloceplhalufi, 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 



vSharpe 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 Ghiengmai 



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



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



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