Severtzoff’s c Fauna of Turkestan 
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. 
134. Sylvia nisoria, SevertzofF, p. 65. 
Horizontal range . Breeds and occurs on passage in districts 
I., II., III., and IV.

in districts 3 and 4. 
135. Sylvia rufa, Bodd. 
Sylvia cinerea , Severtzoff, p. 65. 
Horizontal range. Breeds in districts I., II., III., and IV.

136. Sylvia curruca (L.) ; Severtzoff, p. 65. 
Horizontal range and vertical range similar to those of 
Sylvia rufa . 
137. Hypolais languida, Ehr. 
Sylvia magnirostris , Severtzoff, pp. 65, 123. 
Horizontal range. Breeds and is found on passage in dis¬ 
trict III. 
Vertical range . Is found on passage in district 2, and breeds 
in district 3. 
Dr. Severtzoff informs me that after comparing his speci¬ 
mens wuth 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.
