40 MESSRS. ROBINSON AND KLOSS ON 



The Masked Finfoot is everywhere an extremely rare bird : 

 it is usually found on fairly rapid rivers or small streams, feeding 

 under tlie banks and, when alarmed, moving though the watei: with 

 the aid of its wings, rarely taking properly to flight. 



The ejjfofs of the Masked Finfoot, hitherto unknown, have 

 recently been discovered on the Myitmaka river, Southern Burma, 

 and have been described by Mr. E. C. Stuart Baker in " Bull Brit. 

 Orn. Club," xli, 1921, j). 57. A fuller account of the nidiflation is 

 given by Mr. Cyril Hopwood, " Journ. Nat. Hist. Soc. Bombay," xxvii, 

 1921, pp. 634-636.

The only record for this common Rail from the area is that of 

 Miiller, from the "Malay Peninsula" — presumably adjacent to the is- 

 land of Puket. Our series from the Federated Malay States is also sin- 

 gularly deficient, and as we have no specimens from Java we are un- 

 able to state to which of the named races the Siamese bird should be 

 assigned. Baker calls it gularis (Horsf.), whereas Oberholser (Proc. 

 U. S. Nat. Mus. 55, 1919, p. 478) confines that race to Java, and 

 considers that birds ranging from India to the Malay Peninsula and 

 Cochin-China should stand as H. s. alhiventris Swainson. 



Eight birds in Mr. Williamson's collection, all from the 

 vicinity of Bangkok, agree well with thres from Sumatra, but are 

 paler both ab^ve and below than two from S. W. Borneo which are 

 almost certainly identical with the Javan bird.
