Salicarioe of Dr. Severtzoff. 155 



cides, again, that this bird is an Acrocephalus. The fact that 

 the wings and tail are of nearly equal length decides in favour 

 oi Acrocephalus agricola (Jerd.), and against A. streperus, A. 

 palustris, and A. dumetorum. The wing-formula agrees with 

 A. agricola, and disagrees with A. streperus and A. palustris, 

 whilst the length of wing and culmen confirms A. agricola 

 against the other three. 



Salicaria obsoleta (p. 87) . This bird, with first primary twice 

 as long as the coverts, must be a Hypolais. The bill is said to 

 resemble that of the next species, which is given as 4 lines, 

 or culmen '55, the dimensions oi Hypolais caligata (Licht.), 

 which I take it to be. The wing is shghtly more pointed than 

 usual. 



Salicaria pallida (p. 87) agrees, in length of first primary, 

 wing-formula, length of culmen, wing, and tail, with Hy- 

 polais caligata (Licht.). 



Salicaria tamariceti (p. 88) . Mr. Dresser says that the first 

 primary of this bird is "longer than the wing-coverts;" but 

 ' Stray Feathers ' fortunately adds " twice as long as the 

 coverts,'^ so that there can be no doubt about this bird being 

 a Hypolais. The second primary being equal to the sixth or 

 seventh, and the culmen '62 to '69, incline me to identify 

 this species with Hypolais pallida (Ehr.). My skins from 

 Smyrna vary in length of culmen from •64 to "68 inch, and 

 have the second primary intermediate in length between the 

 sixth and seventh. I am inclined to discriminate the two 

 species as under : — 



H. ratna. Length of wing 2"35 to 2"53, culmen '57 to 

 •68. Second primary between the seventh aiid ninth. 



H. pallida. Length of wing 2"45 to 2' 7, culmen "6 to "72. 

 Second j^rimary between the fifth and seventh. 



Salicaria modesta (p. 88). From the remark in 'The Ibis* 

 that the first primary is rather longer than the coverts, qualified 

 by that of ' Stray Feathers ' that it is scarcely longer than its 

 coverts, we may decide at once that this bird is an Acro- 

 cephalus. The wing-formula restricts the choice to A. agri- 

 cola and A. dumetorum. The remark, " bill small,"^ gives 

 the casting vote in favour of Acrocephalus agricola (Jerd.).
