164. Hoplopterus ventralis Wagl. — The Spur-winged Plover was seldom 

 seen diiring my travcls in Siarn. I only observed it twice, the first time on some 

 sandbanks in the Meli Yome river near the town of Muang Pré, the second time also 

 on the Meh Yome near a place called Vang Nun. They Avere in pairs botli times 

 and were circling along the river uttering a soft whistling.

165. Aegialites mongolica Pall, — The sandbanks round the mouth of the 

 Menam Chao Phaya river were splendid resting places for immense quantities of 

 wading-birds during the winter months, and among these the Lesser Sandpiper 

 was very common, occurring in great flocks of often several hundreds of individaals. 



166. Numenius phaeopus L. — The Whimbrel occurred in great numbers 

 among the wading-birds which had their winter- quarters along the coasts of the Gulf 

 of Siam. 



167. Tringoides hypoleucos L. — The common Sandpiper was infrequently 

 found along the rivers and creeks botli in Northern and Central Siam during the 

 winter months, but never in great numbers. 



168. Totanus glareola L, — The Wood Sandpiper, the breeding range of which 

 is limited to the northern parts of the Palearctic Region, is a common winter visitor 

 in India to Burma. It was also shot sometimes during my journey though it was 

 by no means common in any part of Siam visited by the Expedition, with the 

 exception of the neighbourhood of Bangkok, where I observed it in December 1911.

 always found on the rice-fields and never along the Menam Chao Phaya river.

 on favourable localities during the winter months. Especially in the northern districts
