80 Mr. H. E. Dresser's Xotes on 



Vertical range. Occurs on passage in district 2, and breeds 

 in district 3. 



139. Sylvia mystacea, Men. ; Severtzoff, p. 65. 

 Horizontal range. Breeds in districts III. and IV. 

 Vertical range. Breeds in districts 1 and 2. 



Dr. Severtzoff assures me that he has good reason to be- 

 lieve that Menetries's S. mystacea is really specifically distinct 

 from S. subalpina, although Menetries himself afterwards con- 

 sidered them to be identical. I have therefore treated S. 

 mystacea as a distinct species, although I have doubts as to 

 the propriety of so doing. 



140. Sylvia NANA (Ehr.). 



Atraphornis aralensis (Eversm.) ; Severtzoff, pp. 65, 124. 



Horizontal range. Breeds in district III. 



Vertical range. Breeds commonly in district 1, and is found, 

 though rarely, in summer in district 2. 



At page 124 Dr. Severtzoff writes as follows : — " I may add 

 that the iris of this species is yellow. It does not frequent 

 the reeds, but the most arid desert places, which are covered 

 with bushes of Haloxylon ammodendron or Atraphaxis, where 

 it runs about on the ground and picks up small insects. The 

 generic term Atraphornis I have given to this bird on ac- 

 count of its predilection for the latter plant ; and I separate 

 it from Salicaria on account of its habits, its white legs, yel- 

 low iris, and sharp bill. The young differ from the old 

 birds only by having the plumage softer, and are a little 

 lighter." 



He further describes a species (at p. 121) under the name 

 of Atraphornis platyura, which he now informs me is identical 

 with Drymoeca inquieta, Riipp., which stands under the name 

 of Drymmca gracilis (Licht.) . This species, he says, *' does 

 not occur in Turkestan, but in the south-western part of Tur- 

 coraania. In 1859 it was found on the western shores of the 

 Caspian."
