He gives the soft parts as: Iris in two rings, inner blue, outer pale 

 pink; bill leaden, base greenish yellow; orbital skin green; feet purplish 

 red, claws pale horn brown. 



With a series of 10 males from the Malay Peninsula and Tenasserim 

 and seven males from southeastern Siam, but only one male from 

 Sumatra and one male each from Banka and Billiton, I am unable to 

 see any tangible color differences between the series, and the measure- 

 ments show no appreciable difl'erence in size. 



Ten males from the Malay Peninsula (7) and Tenasserim (3) 

 measure: Wing, 142-155 (149.3); tail, 80.5-100 (87); bill, including 

 cere, 16-17.5 (16.7) mm. Seven males from southeastern Siam 

 measure: Wing, 138-158 (150.5); tail, 79-90 (85); bill, including cere, 

 15.5-17 (16.2) mm. One male from Sumatra, one male from Banka, 

 and one male from Billiton m^easure: Wing, 147.5-150 (148.5); tail, 

 87-94.5 (91); bill, including cere, 16-17.5 (16.6) mm. Five females 

 from the Malay Peninsula measure: Wing, 141-150 (145); tail, 75- 

 81.5 (78.5); bill, including cere, 16-16.5 (16) mm. Eight females from 

 southeastern Siam measure: Wing, 142.5-153 (148.6); tail, 77-87.5 

 (81); bill, including cere, 16-17.5 (16.4) mm. 



Tliis race extends from Sumatra, Banka, and Billiton through the 

 Malay Peninsula from Singapore north to Tenasserim and eastward 

 to southeastern Siam, Cambodia, Cochinchina, and Annam. 



Chasen and Kloss '* record two females from Ban Dong, Ralieng 

 District, western Siam. This is the northernmost record I have seen. 

 It has also been recorded from Bangkok," and it occurs on many islands 

 off the coast in the Gulf of Siam and along the west coast of the Malay
