1 ad. Koou Tan, May 1914. W = 216 mm; T=116 mm; C = 29 mm. — ¢ Koh Lak ?"/11 1914, 
L = 287 mm.; W = 202 mm.; T = 110 mm.; C = 31 mm; Tarsus = 69 mm. — TIrides: brown. Bill: black 
with the base red. Legs: pale yellow. 
Rather common on suitable localities over the whole country. It frequents open, 
sandy plains or open spaces among thin tree-jungle where it runs about either in pairs 
or in small flocks. The birds make their presence known by uttering their characteristic 
notes. When disturbed it never takes to long flights and very soon settles again. 
305. Hoplopterus ventralis. Wacer. — The Indian Spur-winged Plover. 
Hoplopterus ventralis: Gyldenstolpe I p. 69; Gyldenstolpe JI]; Gyldenstolpe III p. 235; Robinson « Kloss p. 11; 
Gairdner p. 152. 
1 ad. Koon Tan 1914. W = 198 mm.; T = 101 mm.; C = 28 mm.; Tarsus = 59 mm, 
Very common along the course of the Meh Ping river. It also occurred along some 
of the smaller rivers of Northern Siam and was generally seen in pairs. Sometimes two 
or three pairs were seen together resting on the floating logs or on stones in the river bed. 
When flying it utters a whistling note which rather resembles that of the Burmese 
Lapwing (Sarcogrammus indica atrinuchalis JERD.). 
306. Squatarola squatarola. Lroyn. — The Grey Plover. 
The Grey Plover is a very rare winter visitor to the coasts of Siam and the Malay 
Peninsula. During my stay at Koh Lak I once observed a single specimen which was 
resting on the sandy beach just outside the village. 
307. Charadrius dominicus fulvus. Gm. — The Eastern Golden Plover. 
Charadrius fulvus: Williamson I p. 48; Gairdner p. 152. 
Charadrius dominicus: Grant p. 118; Bonhote p. 79. 
A winter visitor to Siam but apparently not very common. During my stay at Koh 
Lak I at different occasions observed small parties of this bird on a marshy plain just 
outside the village but the birds were very shy and difficult to get into range. 
308. Ochthodromus geoffroyi. Waai. — The Large Sand Plover. 
Ochtodromus geoffroyi: Robinson & Kloss p. 12. 
Cirrepidesmus geoffroyi: Miller p. 435. 
@ Koh Lak 8/11 1914. L = 194 mm.; W = 135 mm.; T= 55 mm.; C = 23 mm. — 2 Koh Lak 
9/41 1914. L = 180 mm; W = 137 mm; T = 52 mm.; C = 20 mm. — @ Koh Lak 99/1; 1914. L = 190 
mm.; W = 138 mm.; T = 58 mm.; C = 22 mm. — @ Koh Lak 9/11 1914. L==185 mm; W = 136 mm: 
T = 60 mm.; C = 23 mm. — Irides: brown. Bill: black. Legs: greyish yellow. 
The Large Sand Plover seems to be a somewhat rare winter visitor to the coasts of 
Siam and I only found it in small parties along the western coasts of the Gulf of Siam.
