Annam, and in this respect approaclies D. h. Ixidia. The present 

 subspec;ies may be separated from D. b. htulia by its ratlier larijer 

 size, less rich and purplish colour above and paler buff under 

 tail-coverts.

It is doubtful if any rock-pigeons from central and south 



Siam can be regarded as truly wild : we record it for this area merely 



on the strengtlx of a skin from Salanga (Puket), now in the British 



Museum.

"Iris, inner ring yellow, outer orange ; bill, plum coloured at 

 base, whitish horn at tip ; feet pinkish maroon." 



This fine pigeon is fairly common in the winter months on 

 the islands off the west coast of Siam, though whether it is a resident 

 or a seasonal visitor is unknown, as collecting is inconvenient or im- 

 possible in these localities during the sunnner. On the east coast 

 it is apparently much rarer. Our series shows that the sexes are 

 practically alike, females with the grey cap similar to adult males, 

 but with the undersurface with slightly les-? gloss and more brick-red, 

 less purplish in tint. 



On Koh Muk, in January 1917, they were roosting in man- 

 groves behind a sandy beach, apparently feeding on the mainland, 

 distant about three miles, during the day.
