Figure and descriptions W. Bias, f IV-, Salvad. f 1, f 6\ Wardl. Bams, f 5, 
Diagnosis. Average size larger; metallic cervical collar of male usually magenta-purple; 
crown and under surface of female usually more saturated with rufous chestnut. 
Distribution. Great Sangi (Bosenh. d 7,* Hoedt d 1, etc.); Siao (Hoedt d 1, v. Duivenb. 
d 1, Meyer f 2, Nat. Coll.). 
Observation. This race, besides bemg of larger size, has been held by Count Salvador!, Prof. 
W. Blasius and Major Wardlaw Bamsay 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 apparently of similar age from the 
mainland of Celebes and the mtermediate islands. The darkest specimen we have 
seen is an adult male from Tagulandang (C 13461), with a bronze cervical collar. 
As seen by the measurements below there is a complete intergradation in point 
of size.
