 Nr. 2048). 



Iris red-brown; bill and feet blue-grey (Platen). 



Measurements. Wing 126 nmi; tail 117; tarsus 21; bill fi-om nostril 17. 



Distribution. Great Sangi (Platen). 



We are indebted to Mr. Nehrkorn for the loan of the type of this species. 

 It was one of the discoveries made by Dr. & Mrs. Platen during their stay in 

 Great Sangi in 1886/87. Only two specimens, both males, were obtained. Their 

 specific validity is clearly established by Prof. W. Blasius. The yellow loral 

 region is the best characteristic of /. platenae.
