Severizoff’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 of 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 sogdianensis, 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.
