3. Accentor koslowi^ sp. n. 



This species may be referred to that group of Accentors to 

 which belong A. modularis orientalis and A. rubidus fervidus, 

 but differs from these in not having striated ear-coverts — a 

 distinction which might separate it into a special subgroup. 



Notseo toto brunnescente-fulvo, longitudinaliter sordide brun- 

 neomaculato; uropygio concolore. Pectore abdomineque 

 fulvescente-albis ; corporis lateribus longitudinaliter 

 brunneo maculatis ; gula pallide fusca ; regione parotica 

 baud striata. Marginibus tectricum alarum duas fascias 

 pallidas transversas fingentibus. Femina mari simillima. 



Dimensions : — 



The 1st primary is a little shorter than the upper coverts ; 

 2 > 7 ; 3rdj 4th^ and 5th are the longest and equal ; 6th is 

 only a little shorter than these. In the tail the outermost 

 pair of rectrices are 4-6 millim. shorter than 4th = 5 >6. 



The bill is blacky the base of the mandibles light horny ; 

 feet flesh- coloured^ nails dark horny. Eyes light hazel. 



In winter plumage, four males, one female, and two of 

 doubtful sex have the upper part of the head and body 

 yellowish light brown, with blackish spots on the shafts, 

 more distinct on the back and less so on the nape and 

 head. On the forehead these spots merge into a general 

 light-brown colour ; upper tail-feathers spotless, except 

 occasionally on the longest of the upper tail-coverts. The 

 throat is a smoky brown, in the lower part with whitish 

 tips, not worn off in December and January, forming an 

 indistinct half-collar on the neck ; ear-coverts are the same 

 dusky brown, but with no bars on the shafts ; neither are 

 there superciliaries. The underparts are yellowish white, 

 with a brown tinge on the breast, reddish on the flanks, 

 where the posterior feathers have dark bars on the shafts ; 

 lower wing-coverts rufous white, without spots. Rectrices, 

 quills, and upper wing-coverts brown, with tawny margins, 

 wider on the hinder quills and wing-coverts. Yellowish- white
