136 ZOSTEROPS VIRESCENS. 



belongs to a quite different groupe (distinguished by the 

 unicolorous tailfeathers) and is nearest allied to Ps. notata 

 Salvad., from which it differs by the want of one (or two) 

 light crossband on the wings; moreover Fs. notata has no 

 indication of a light temporal stripe and is underneath 

 distinct pale yellowish. 



7. Zosterops lettiensis, n. sp. 



Very similar to Z. Grayi Wall, (from Key and Aru) 

 but above not so bright olive-yellow, but more greenish 

 yellow, rump and upper tailcoverts like the back (not 

 bright yellow as in Z. Grayi) ; yellow frontal margin 

 not so distinct as in Z. Grayi, confined to a yellow loral 

 stripe ; the yellow on chin, throat and lower tailcoverts 

 not so dark and bright as in Z. Grayi; remaining under 

 parts nearly the same as in Z. Grayi, but the flanks 

 darker washed with isabelline; a faint yellowish longitu- 

 dinal stripe along the centre of the abdomen. Smaller 

 than Z. Grayi.
