280. Anas poecilorhyncha. Gm. (?) The Spotted-billed Duck. 



During my journey down the Meh Ping river from Chieng Mai to Paknana Po I obser- 

 ved a small party of Ducks on the 8th of October 1914 a few miles soutb of Keng Soi. 



Unfortunately I did not obtain a specimen but they were probably Anas poecilo 

 rhyncha, Gm. 



281. Nettopus coromandelianus. Gm. The Cotton Teal.

The Cotton Teal was not so common as the Whistling Teal, though it occurred al 

 the same localities. I never observed larger flocks than about 8 — 10 birds and most often 

 they were met with in couples. This species likes large swamps best of all and especiallj 

 those where the water is fairly deep and where there are reeds or high grass to conceal 

 in. They dive exceediiigly well and generally escape by diving when not mortallv wounded. 



282. Dendrocygna javanica. Horsf. — The Whistling Teal.

The Whistling Teal was very abundant in some of the larger swamps of Northern 

 and Central Siarn. It also occurred in the larger rivers where the current was not to swift. 



Åt these last-mentioned places it was, however, always more rare than in the marshy 

 country. Sometimes I even found them among the high grass on the paddy fields. 



283. Dafila aquta. Linn. The Pintail. 



The Pintail seems to be rare in Siarn. The only specimens I observed, were those 

 kept in confinement by the Laos Prince of Chieng Mai, and which had been obtained 

 at Pra Yao, a small town in Northeastern Siarn. 



During my travels in different parts of the väst country I never met with a single 

 specimen in wild state. 



284. Querquedula querquedula. Linn. — The Garganey Teal. 



Querquedula querquedula: Gairdner p. 153. 

 Querquedula circia: Williamson I p. 48. 



Seems to be confined to the larger rivers and the inner parts of the Gulf of Siarn. 

 Here it, however, only occurred quite close to the shore. 



In the inland lakes and swamps it was never met with during my journey.
