 1911. [Nos. 189, 1281, C. H. B. G.'] 



The type-specimen, obtained by "Wallace in the Aru 

 Islands, is in the British Museum. The Mimika specimens 

 differ slightly from most of the typical examples from Aru 

 in having the chin more conspicuously white and the pearled 

 spots on the chest larger, but, as in R, threnothorax, this 

 character is liable to vary individually. From the latter 

 species it may be at once recognised by the white tips to the 

 tail-feathers. 



In the male the wing measures 81 mm. ( = 3*2 inches) and 

 in the female 77 mm. (3'05 inches). 



In typical examples from the Aru Islands the wing 

 measures : — 



Males 78-82 mm. ( = 3-l-3-25 inches) ; females 71 mm. 

 (=2-8 inches).
