1 d". West side, Koh Samui, Bandon Bight. 6 May, 1913. 



Wing (dry) 103 mm. 



" Iris and orbits red ; bill bluish green ; legs pale coral ; claws 

 black." 



The typical form of this species was described from the 

 Philippines : and birds from Java, Sumatra and the south of the 

 Malay Peninsula, named Rallus ruhlginosus, Temm. PI. Col. pi. 357 

 (1825), are identical with it, all having the wing 98 mm. or under. 



Chinese and Japanese birds, L. f. erythrothorax, are said to 

 have the wing over 105 mm., while Indian (Nepal, etc.) birds, figured 

 and named by Hodgson as Zapornia Jiammicejji^, but apparently 

 never described, are stated by Sharpe (Cat. Birds Brit. Mus. xxiii, 

 1894, p. 147) to be intermediate. Southern Indian birds are as small 

 as Malayan, but have not been named. 



Mr. Hartert has named the N. Indian bird Porzana f. hakeri 

 (Nov. Zool. xxiv, 1917, p. 272), type from Kumaon. 



We have examined twelve specimens in Mr. Williamson's col- 

 lection (eleven from near Bangkok and one from Meklong), shot in 

 the months January to May. They differ from Sumatran and Malayan 

 birds in having the wing from 103-112 mm., against a maximum of 

 98, and in being paler in tint both above and below. The extent of 

 the red on the crown is a variable quantity. We regard them all as 

 belonirinij to this race and not to P. f. hakeri.
