Specimen No. 204, which appears to be an immature female, 

 has the basal part of the lower mandible yellowish-white, the

 call-note, and when seen at close quarters the male looks 

 rather quaint with the white ruffle encircling its head.^'

 M.Jlaviventer Gould, which is distinguished at a glance from 

 the several New Guinea species by its black ear-coverts and 

 olive-green back in the adult stage. This is an instance of
