uniform whitisli, strongly washed witli buff on the breast. The 

 crowns are chestnut, streaked with black, and the frontal w^attles are 

 smaller than in dark bellied birds. Possibly they represent a non- 

 breeding, as distinct from a juvenile, plumage. Ten specimens in 

 Mr. Williamson's collection from various parts of Siam, dated Novem- 

 ber to April, all have the under surface black.

This Jacana, with white lower plumage (winter^, was shot 

 on a shallow lagoon together with grebes and the preceding species. 

 It has not hitherto been recorded from Siam, with the excep- 

 tion of Gairdner's and Stuart Baker's specimens. Mr. W. J. F. Wil- 

 liamson informs us, however, that he found the bird in considerable 

 numbers at Kloncr R'ano-sit, a little to the north of Bangkok, in 

 Jatmary 1916, on flooded ground largely covered with reeds and 

 coarse grivsses. In the Malay Peninsula it is widely distributed but 

 extremely rare.
