The large series from Korinchi differs from descriptions 
and figures of Forbes’ birds, in haying the middle of the belly 
distinctly white with only a light primrose suffusion and the 
flanks markedly buffy brown. 
Under the circumstances we are inclined to think that 
the balance of probability is in favour of the hypothesis that 
the Padang and Korinchi birds are identical, while the Dempo 
form is unnamed, rather than that the Padang and Dempo 
birds are both Z. montana, but are separated in Korinchi by 
another form. 
The Dempo bird, therefore, lacks a name but may be 
cited as 
Zosterops difficilis sp. nov., 
the type being the specimen in the Liverpool Museum 
figured by Robinson, while an adequate description is given 
by Sharpe (Cat. Birds Brit. Mus. ix, p. 191 (1884).

“Tris hazel, or light brown, upper mandible black, lower 
slate, the tip black, feet slate.” 
In the absence of direct comparison of specimens from 
Kina balu it is impossible to be certain whether Zostevops clara, 
Sharpe, (Ibis 1888, p. 479; 1d. op. cit. 1889, p. 427; id. op. cit. 
1890, P]. VII, fig. 2), which is regarded as identical by Finsch, 
is distinct from this species. 
Our five specimens agree exactly with Salvadori’s descrip- 
tion of the three original specimens obtained on Singgalang by 
Beccari, but when compared with Sharpe’s description and 
figure quoted above, present the following differences. The 
grey of the belly and flanks is slightly darker, the black of the 
forehead extends very considerably beyond the eyes and the 
eye Is completely surrounded by a black ring exterior to the 
silky white one. 
The species are certainly very closely allied, but in view 
of the circumscribed areas inhabited by so many species of 
the genus it will be, we think, advisable to regard Z. clara as 
at anyrate a distinct subspecies.
