Type. Sex inc. Kuatun^ N.W. Fohkien, late winter, 



i9ii. 



Three examples from Kuatun, all exactly similar, have 

 been compared with a mounted bird in good condition 

 given to me by P^re David out oH his private Paris 

 Collection. I had previously considered this specimen, 

 which is labelled " Ssetchuan occ. 30 Janvier, 1869," as 

 darkened by smoke and exposure. A more careful exami- 

 nation, however, has revealed that this is not so ; the upper- 

 parts and the flanks are actually of a warm chestnut-ochre, 

 the surface of the tail of a very bright chestnut, and the 

 lores and eye-region are much marked with black as in 

 8. morrisoniana 0. -Grant. The wing in this specimen 

 measures 52 mm., but Pere David in ' Les Oiseaux de 

 la Chine ' gives wing-measurements as 50 mm. 



Heteroxenicus joannsB, sp. no v. 



Adult female. Dark olive-brown above ; the upper tail- 

 coverts, upper surface of tail, and outer webs of primaries 

 and secondaries (innermost excepted) light and somewhat 

 dull fulvous-brown. Lores and sides of head and neck olive- 

 brown. Pale olive-brown breast and flanks ; centre of the 

 breast tinged with buff^ rest of underparts pure white. Iris 

 dark brown ; bill blackish^ base of lower mandible greyish ; 

 mouth pink ; legs pale violet. 1st primary about half of 

 2nd, 2nd = 10th, 4th and 5th equal and longest, the 3rd 

 primary just below the 6th. Bill stout, broad at base ; 

 culmen 13'5 mm.; wing 70 mm. ; tail 51 mm.; tarsus 27. 



Type. Ad. ? . Mengtz, S.E. Yunnan, 3 May, 1921. 



No male was procured or seen. 



Phylloscopus proregulus yunnanensis, subsp. nov. 



Adult male. Differs from P. p. proregulus in the much 

 less distinct head-stripes, the coronal stripe being but 

 imperfectly indicated, the superciliary stripe paler and 

 greener ; in the secondaries being edged throughout with 



./.
