(1932). The species is also known from Mae Sariang, where I took 

 specimens on October 26 and 27, 1936. 



I have found this bird only occasionally and in small flocks, among 

 dry rice stubbles and on such grassy areas as the aviation field west of 

 Chiang Mai. 



One of my specimens had the irides dark brown ; the bill black ; the 

 feet and toes slate color ; the claws black. 



Any example from our region will probably be in winter dress, 

 when it has the upperparts dark brown or blackish, heavily spotted 

 everywhere with whitish and golden-yellow ; the underparts white, the 

 throat and breast more or less washed with golden-buff and more or 

 less streaked with brown. In nuptial plumage it has the forehead, 

 supercilia, sides of neck, and breast white ; the remaining underparts 

 black ; the other parts much as in winter but more deeply colored. 



There is a slight chance that the European golden plover, Pliwialis 

 apricaria apricaria, may some day be found in northern Thailand ; it 

 has the axillaries pure white, while the present form has them brownish 

 gray. There is a much greater possibility that the gray plover, 

 Squatarola squatarola, will occur in our provinces; it may be recog- 

 nized by its black axillaries and the presence of a small hindtoe. The 

 golden plovers have no hindtoe at all.

I took two specimens of the Palearctic race of the little ringed plover 

 on the Mae Ping at Chiang Mai, December 29, 1930, and a third on the 

 same river at Chom Thong, November 7, 1935. It is probably often 

 overlooked among the much more numerous individuals of the follow- 

 ing form. 



The bird of November 7, a female in first-winter plumage, has the 

 outermost primary partly ensheathed (about two-thirds grown). 



The specimens of December 29, a male and a female in the first win- 

 ter dress, had the irides dark brown ; the edges of the eyelids yellow ; 

 the bill black, yellow at the base of the mandible ; the feet and toes 

 fleshy yellow; the soles fleshy; the claws black. 



It is perhaps not possible to identify this bird in the field with any 

 certainty. It is extremely close to the resident race in plumage but 

 has a longer wing and bill. Most Thai examples are young birds in 

 the first winter plumage, wholly lacking a black band on the f orecrown 

 and having the breast band either black mixed with brown, the feath-
