“Tris hazel, bill slate, culmen and tip black, feet pale 
slate.” 
This species was not common at our camp at 7,300 feet, 
below which level it did not occur, but as the mountain 
was ascended became very abundant until the zone of 
dwarf shrubs was reached, where it far outnumbered in 
individuals all other species taken together. It flew in 
small flocks of four or five to over a dozen and fed on the 
flowers of the Rhododendrons and Vaccinium which formed 
the major part of the vegetation. It utters a low but 
melodious little song on three notes. Though most abundant 
on the upper verge of the forest at about 10,000 feet it also 
ascended towards the extreme limit of vegetation at over 
11,000 feet. 
The large series of over forty specimens is very constant 
in characters. Young birds are duller in colour and have the 
yellow of the throat more greenish and that of the forehead 
less differentiated from the rest of the head. The brownish 
ashy of the flanks is not so marked. 
There seems considerable doubt as to what the proper 
name of this species is, so we have followed Finsch in his 
determination. 
It is practically certain that the records of the occur- 
rence of Zosterops chlovates, Zosterops fallax, Oveozosterops 
javanica and Oreozosterops montana given for this island by 
Vorderman (loc. cit. supra), are all in reality referable to this 
species which Is in all-probability to be found on most of the 
Volcanoes in the island rising above 8,000 or 9,000 feet. 
All recent descriptions of Zosterops chlorates are founded 
on specimens obtained by Forbes on the Dempo (10,000 feet) 
and agree in stating that the abdomen is golden yellow while 
the flanks have a ruddy tinge: the figure given by Robinson > 
(Bull. Liverp. Mus. II, p. 11, fig. 1 (1899)) agrees in these 
particulars. According to Finsch (loc. cit.) the types of 
Z. montana and Z. chlorates in the Leyden Museum, collected 
by Miiller, are identical and, though no precise locality is 
available, must have been collected somewhere in the Padang 
Highlands, probably on Singgalang or Merapl.
