428 LETTERS TO THE EDITOR. 



Phyllopnenste intermedia, (to Reguloides), and Hypolais graminis, 

 from the difference of beaks, but afterwards saw that the 

 characters of beak which distinguish generally Phyllopneuste 

 from the green Hypolais are here only individual. 



50. — My Phyllopneuste fidvescens is Ph. tristis, Gould. 



51. — My Accentor fidvescens is described and figured by 

 Gould, Birds of Asia, part XXIII, as the female of A. 

 montanellus — but wrongly. I have got males and females of 

 A. fidvescens, without any sexual difference in colour; but it 

 mav be montanellus, Var., fidvescens, subtus concolor, ma- 

 culis nullis. Collected by Stoliczka and Biddulph. 



52. — A. atrogularis, Brdt. = ^4. Huttoni, Moore. 



53. — A. alta'icus, Brdt. = ^. variegatus, Blyth. 



54, — Lusciola Hafizi : larger than the European L. luscinia ; 

 above olive-brownish grey, not rufous brown; only rump 

 and tail rufous. Wing more rounded; quills 2 = 5, 3 = 4 

 longest, or 3 74 7 275; or 2=5, 3 74; or 3=4 7 5 7 2 7 6 ; 

 In the nightingale the quills 2=4 7 3. Song also different, 

 much plainer. Length, 7*6; wing, 3'6^ ; tail, 3*1 2. Tail- 

 coverts reaching above and below to the middle of the tail. 

 It is L. philomela, Pall, nee Beckst, and differs constantly from 

 L. luscinia by size, colour, and song ; and generally, though 

 not without intermediate specimens, by a more rounded wino-. 

 The difference is just as great as between the European 

 L. luscinia and L. philomela, Bechst. nee Pall. (L. cedon, 

 Pall). 



55. — L. Goltzii, Cab. : Larger than my R. Hafizi, darker, with 

 longer tail and longer tail coverts, upper and lower. I have 

 not here in London, either specimens, or my note-book with 

 comparative diagnoses ; but I found both on the Lower Oxus, 

 and observed that they cease to sing at different times. L. Golt- 

 zii before moult in July, and L. Hafizi conserving a very 

 shortened, but real song some time still after moult, to the end 

 of August. 



56. — Pyrophthalma mystacea, Men., is allied to Curruca suhal- 

 pina, and has the same pure white moustach-band ; but the head 

 black, not grey, and lighter rosy-vinaceous throat and breast. 

 P. mystacea is a true Pyrophthalma by its swollen bright 

 orange eye-lids. 



bQbis. — The Turkestan Sijlvia orphea, by its long bill, is iden- 

 tical with Sylvia Jerdoni of India. 



57. — Ruticilla caimdeocephala, Gould = R. lugens, Sev. In 

 autumn with pure cinereous, dusky -tipped crown instead of the 

 slightly greyish blue of the spring-plumage ; all the black also 

 with large dusky tips ; these autumn birds were just my Ruticilla 

 lugens ; now I have also typical spring-specimens from the Tian- 

 shau mountains.
