There appears to be no difference between the summer and winter 

 plumage of this bird, judging from the specimens I have been able 

 to examine. 



Distribution. Anderson procured this species at Momein, on the 

 Chinese frontier ; Wardlaw Earn say at Toungngoo ; and Davison 

 on Muleyit mountain, in Tenasserim. It also occurs in Sumatra. 



G-enus PBINIA, Horsf., 1821. 



The genus Prinia comprises seven Indian species of birds, which 

 only differ from Franklinia in having ten tail-feathers instead of 

 twelve. 



They all have a complete spring moult, accompanied in some 

 instances by such a change in colour and in the structure of the tail 

 as to have given rise to great confusion among authors regarding 

 the number of species. The ample materials now available suffice 

 to bring this difficult group of birds into order. In fact but little 

 remained to be done after iSharpe's masterly treatment of the group, 

 and my own observations have chiefly served to corroborate his. 

 To Hume and Brooks, however, is due the credit of having first 

 furnished the clue by which the present order has been arrived at.
