222 Mr. C. Boden Kloss on Birds [Ibis, 



Bazaar (wing 84 mm.) and a specimen from Dehra (wing 

 88 mm.), the feathers of the top of the head of the Koh Lak 

 and Bangkok birds are smaller and more acuminate with 

 sandy edges, forming a finer chequering of dark and light]; 

 the nape and mantle are similarly coarsely patterned, and the 

 breast-stripes and abdomen are as in the Calcutta bird (those 

 on the Dehra specimen are more like indistinct spots than 

 stripes, and the middle of the abdomen is lighter) ; but they 

 differ from both the Indian specimens in having narrower, 

 much more acuminate tail-feathers — a feature to which 

 Mr. Stuart Baker has already drawn attention.

Mr. Williamson states that this bird is common at Bang- 

 kok (typical locality) in the fields and along suburban road- 

 sides. I only met with the one example in eastern Siam ; 

 it was obtained in open ground covered with long grass, and 

 ■when disturbed took short flights of twenty yards or so ; 

 I had to flush it several times before I could drop it into 

 a little space of short grass where there was no risk of 

 losing it.

Described from a pair obtained at Aynthia, central Siam, 

 this race is apparently the south-eastern representative of 

 M. microptera Hume, of Pegu. Compared with a pair of the 

 latter obtained by Bingham at MandaJay (wings 74 & 71 mm.)
