This species can readily be distinguished from the capensis forms 

 occurring in Siam by the seal-brown back and wings and the ochraceous- 

 orange pileum. 



The species ranges from eastern Bengal to Assam and south tlirough 

 Tenasserim and western Peninsular Siam to the Langkaw^i group of 

 islands. Robinson and Kloss ^^ state that they are not aw^are that it 

 has been met with on the east coast of the Peninsula; it is fairly com- 

 mon along the west coast but is never found far from salt water. 

 Robinson ®* records it from Pulo Terutau and Pulo Dayang Bunting, 

 Langkawi Group.

 April 10, 1926; one male, Muang Kanburi, April 15, 1928; one male, 

 Koh Lak, June 22, 1933. 



This form is a considerably lighter blue on the mantle and wing8 

 and the head is a lighter brown (drab) than the next form (ma!ac- 

 censis); it is also somewhat larger. Ten males from Siam proper 

 measure: Wing, 146.5-159 (151.5); tail, 92.5-105 (97.7); culmen, 

 77-90 (84) mm. Five females: Wing, 146-164.5 (156); tail, 84-104 

 (97.7); cuhnen, 81-86 (84) mm. 



The race ranges from Buraia south to Siam and east to Cambodia, 

 Laos, Cochinchina, and Annam. In Siam proper it is found resident 

 all over the comitry and southward in the southwestern part as far as 

 Koh Lak at least. 



Robinson and Kloss °^ record it from Hat Sanulv, near Koh Lak; 

 Namchiik, Pakchan, and Kandhuli Chaiya; the two latter localities 

 are in Peninsular Siam, and the last is at about the southern limit of 

 its range in this direction. 



Specimens from Bandon ai^e more or less intermediate between 

 hurmanica and malaccensis, but nearer tlie latter. 



Herbert ^^ states that in central Siam it is resident in the fnut gar- 

 dens, where it breeds in hollow trees; four nests were found on the
