Severtzoff's 'Fauna of Turkestan.' 79 



three forms of the present species, which he describes, but 

 without giving them separate names. I have carefully read 

 these descriptions, and cannot but think they refer to but one 

 species, especially as he adds that he has found many inter- 

 mediate examples.

Dr. Severtzoff informs me that after comparing his speci- 

 mens with the type oi H. languida in the Berlin Museum, he 

 has no doubt as to their being identical. He also points out 

 to me that the bird I described (Ibis, 1874. p. 420) under the 

 name of Acrocephalus sogdianetisis, is a true Hypolais, closely 

 allied to H. languida, but differing in the arrangement of pri- 

 maries and length of the wing; and judging from the varia- 

 tion in specimens of H. languida obtained by him, he thinks 

 it not improbable that the two {H. languida and H. sogdia- 

 nensis) may prove to belong to the same species.
