Salicarise of Dr. Severtzoff. 
cides, again, that this bird is an Acrocephalus. The fact that 
the wings and tail are of nearly equal length decides in favour 
of 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 of Hypolais caligata (Licht.), 
which I take it to be. The wing is slightly 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 
f Stray Feathers 9 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. rama. Length of wing 2’35 to 2’53, culmen *57 to 
*68. Second primary between the seventh and ninth. 
H. pallida. Length of wing 2'45 to 2*7, culmen *6 to *72. 
Second primary between the fifth and seventh. 
Salicaria modest a (p. 88). From the remark in ‘The Ibis’ 
that the first primary is rather longer than the coverts, qualified 
by that of c Stray Feathers 3 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, u bill small/'’ gives 
the casting vote in favour of Acrocephalus agricola (Jerd.).
