56. Tringa platyrhyncha (Temm.), Zhe Broad-billed 
Stint. 
A specimen was shot by H. R. H. the Prince of Chumpon in 
April 1917, at the mouth of the Chao Phya river. The only previous 
record I can trace is that of Ogilvie-Grant (Fasc. Malay., Zool. ili 
(1905), p. 118), who reports an individual of this species obtained 
at Kampong Budi, Patani, Peninsular Siam, in September 1901. 
Family LARID#—Gulls and Terns.

22. Bangkok, Central Siam, April 1918. 
T.L. 451, 445 mm. W. 325, 330.

Eyelids and bill deep lake-red. Legs dull red to lake-red. Claws 
dark horn-colour. | 
Gyldenstolpe includes this species in his list of Siamese birds, 
but as no particulars of specimens are given, it is to be presumed he 
did not procure any. He states that it is common along the northern 
coast of the Gulf of Siam, and that it also occurs a few miles up the 
Chao Phya river, but never as far up as Bangkok. The last part of 
this statement is incorrect. I shot the above two Bangkok specimens 
opposite the Bombay Burma Trading Corporation’s sawmill, and [ 
have seen others at different times, higher up the river, including a 
party of 8 or 10 flying up-stream past the Custom House. The fact is, 
this bird is quite common on the river during the winter months, right 
up as far as Bangkok, though it is only to be seen during certain | 
phases of the tide—coming up with the flood and going down with 
the ebb.
