"Simbookoo", Siao, Nat. Coll. 



"Buaho mohamo". Great Sangi, iid. 



Figure and descriptions W. Bias, f IV; Salvad. f 1, f G; AVardL Rams, f 5. 



Diagnosis. Average size larger; metallic cervical collar of male usually magenta -pui-ple; 

 crown and under surface of female usually more saturated with rufous chestnut. 



Distribution. Great Sangi (Rosenb. d 1, Hoedt d 1, etc.); Siao (Hoedt d 1, v. Duivenb. 

 dl, Meyer f 2, Nat. Coll.). 



Observation. This race, besides being of larger size, has been held by Count Salvadori, Prof. 

 W. Blasius and Major Wardlaw Ramsay to be recognisable by its having a 

 darker upper surface. As far as the colour of this part is concerned we find it 

 easy to match the Sangi race with specimens apj^arently of similar age fi-om the 

 mainland of Celebes and the intermediate islands. The darkest specimen we have 

 seen is an adult male fi'om Tagulandang (C 13461), with a bronze cervical collar. 

 As seen by the measurements beloAv there is a comjilete intergradation in point 

 of size.
