We have had examples of this bulbul from East and West 

 Java compared with Horsfield's type in the British Muse am 

 and find that the latter is an East Javan bird: P. b. teng- 

 gerensis Van Oort (Xotes Ley den Mus. XXXIV, p. 46, 1911/ 

 1912) is therefore a synonym. Birds from Sumatra and West 

 Java are indistinguishable and differ from P. b. bimaculatus 

 in the greater extent and intensity of the "yellow ear-coverts, 

 in the slightly increased amount of olive in the upper surface, 

 brighter edges to the wing and tail feathers and slightly 

 browner, less black, throats : for these we propose the name : —
