THE BIRDS OF SOUTH-WEST AND PENINSULAR SfAM- 395 



This specimen is an example of Grant's Z. tahaiiensis, with 

 a number of which we have compared it. But it is also very prob- 

 able that they are conspecific with Salvadori's Z. mesoxantha, from 

 Karenne' (Ann. Mus. Civ. Gen. (2 A) vii, 1889, p. 396 ; Taho, near 

 Tounghoo), with the description of which they seem in accordance. 

 Grant probably overlooked this form, for otherwise, seeing that it is 

 obviously the closest ally, if not strictly identical, it would certainly 

 have been mentioned : until we can prove, however, that tahmnensi.s 

 is synonymous with mesoxantha we use the name we are certain of.

 feet slate ".

571. Zosterops palpebrosa Temm., subsp ? 



Zosterops pcdpebrosa, E., p. 7.5 (Tanjong Patani). 



A skin obtained by Gen. E. W. Trotter at Patani, in April 1916, 

 appears to belong to this species; but it is much damaged and we 

 are unable to refer it to any particular race. It is doubtless the 

 same as the two specimens from Tanjong Patani recorded by Grant 

 as Z. palpebrosa (E., p. 75). As compared with an example of Z. p. 

 simplex, from Kukiang, China, the throat is a richer yellow, as in Z. a. 

 aurelventer. Wing 50, tail 38 mm.
