Distribution. Sula Islands (Allen a 1), Peling and Banggai (Nat. Coll.). 
This Bulbul was one of the new forms obtained by Mr. Wallace’s assistant 
in the Sula Islands. It was subsequently found by our native hunters in Peling 
and Banggai. It is a yellower species than I. aureus, with a longer bill.

Nr. 2048). 
Iris red-brown; hill and feet hlue-gi-ey (Platen). 
Measurements. Wing 126 mm; tail 117; tarsus 21; bill from 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 I. platenae.
