We have received the following letters addressed '^ to the 

 Editor '^— 



Sir, — Last year, wheu working out a collection of birds 

 from Yunnan, I made a very careful examination of all the 

 specimens of the various forms of Prinia inornata Sykes, 

 contained iu the Triug and British Museums. In reviewing 

 the different forms of this species in the 'Novitates Zoo- 

 logicse/ vol. xix. p. 299 I drew attention lo the fact that 

 the bird inhabiting Yunnan and Upper Burma as well as 

 that found in Formosa diverged somewhat from the typical 

 Prinia inornata extensicauda Swinhoe, from Amoy, but as 

 many of the older specimens lacked precise data, I refrained 

 from describing them. Since then Major H. H. Harington, 

 with additional material of his own, has named both birds 

 (Bull. B. O. C. vol. xxxi. p. Ill), calling the former P. i. 

 hurmanica and the latter P. i.formosa. It seems to me that 

 in only referring to the colours of their plumage he has 

 missed their most striking characteristics, namely, the dif- 

 ference in the size of their bills.
