ZOSTEROPS AUREI VENTER. 



(1) Zosterops aureiventer aureiventer Hume, Str. Feath. 

 vi. 1878, p. 519 : Tavoy. 



Differs from all forms of palpehrosa in its short black tail, 

 measuring 30-32 mm., as against 34-37 mm. The green 

 margins to the tail-feathers are absent or obsolete and the 

 tail is practically black. There is a definite yellow streak 

 down the centre of the breast, and bellj, and the flanks are a 

 very pale grey, albescent where they meet the yellow stripe. 



Distribution. Tenasserim and south along the coast 

 through the Malay Peninsula and north through Kaiennee 

 into the southern Shan States. 



Zosterops mesozantha (Salvadori, Ann. Mus. Civ. Geneva, 

 vii. 1889, p. 396 : Karen Hills) is a synonym of this form.

 p. 167 : W. Java. 



Vent and abdomen broadly yellow, flanks dark grey. 

 Wino- 48-51 mm. 



Distribution. Java, Sumatra, Borneo. 



(3) Zosterops aureiventer tahanensis Ogilvie-Grant, Bull. 

 B. 0. C. xix. 1906, p. 10 : Gunong Tahan, Pahaug. 



I cannot separate this bird, in any way as regards colour, 

 from buxtoni, but it is a trifle larger, wing 49-50 mm. As 

 they overlap so greatly this hardly seems a sufficient reason
