Of the six species described, four — Ch. ater, Ch. scintillatus, Ch. duyvenbodei, and 

 Ch. chloropterus — have been found in one or other part of New Guinea itself, and 

 Ch. insignis in Amberpon Island in Geelvink Bay. Ch. scintillatus is found not only in New 

 Guinea, but in tbe Aru Islands also ; and Ch. ater, which inhabits the island of Salwatty as 

 well as the mainland, is represented in Mysol by the very closely-allied form Ch. bemsteini.
