I am tempted to consider Prinia rufcscens and its races merely the 

 more eastern forms of the species named Pr. socialis by Sykes. 

 Judging by the literature, however, there seems to be considerable 

 overlapping of ranges in the eastern Himalayas and Assam and, as- 

 suming that such overlapping is real, rather than merely apparent, I 

 keep them, at least for the present, distinct specific entities.

With the inclusion of the genus Franklinia Jerdon 1863 in Prinia 

 Horsfield 1821, Prinia gracilis Franklin 1831 is preoccupied by Sylvia 

 [z^Prinia] (7raa7/.s Lichtenstein 1823 and Blyth's Pr[/»/a] Hodgsonii 

 again comes into use for the bird of Central India, thus becoming 

 untenable for the Himalayan race, which may be called Prinia hodg- 

 sonii rufida God win- Austen 1874. 



Of Prinia hodgsonii, I find at least four forms in the Indo-Chinese 

 countries.

 tion, Ticehurst and Whistler, Ibis, 1939, p. 763), not Sylvia gracilis Lichten- 

 stein 1823.
