Salicariaj of Dr. Severtzoff. 153 



Salicaria microptera {Stray Feathers, iii. p. 425) is a new 

 name given by Severtzoff to the preceding species to re- 

 place S. brevipenriis, Sev. nee Dohrn, and consequently also 

 sinks into a synonym of Hypolais caligata (Lieht.). As 

 a further confirmation of this identification, I may say that 

 ■ the length of wings and tail agree, as also the slightly rounded 

 tail, and the wing-formula, — second equals seventh, or inter- 

 mediate between sixth and seventh ; whereas in H. rama I 

 find that out of five skins in my collection, in two the second 

 primary is between the seventh and eighth, in two equal to 

 the eighth, and in one between the eighth and ninth. 



Salicaria capistrata (p. 84) is an Acrocejjhalus, not a Hypo- 

 lais, the first primary being only the length of the wing-coverts. 

 The wing-formula — second primary equals the eighth — dis- 

 poses at once of A. streperus and A. pains tris. The choice 

 therefore lies between A. agi'icola and A. dumetorum. The 

 principal characters of these two birds may be summarized 

 as under : — 



A. agricola. Length of wing 2"35 to 2"15, tail about the 

 same. Second primary varying in length from between the 

 sixth and seventh to between the eighth and ninth. Culmen 

 •56 to -52. 



A. dumetorum (p. 84). Length of wing 2*5 to 2'35, tail 10 

 per cent, shorter than the wing. Second primary varying in 

 length from between the fifth and sixth to between the seventh 

 and eighth. Culmen '74 to '64. 



In every particular S. capistrata agrees with the former 

 and disagrees with the latter ; I therefore without any hesi- 

 tation identify this bird with Acrocephalus agricola (Jerd.), 

 and note that Severtzoff himself (Stray Feathers, iii. p. 425, 

 clause 33) comes to the same conclusion. 



Salicaria magnirostris, Lilj. (p. 84). This bird has been 

 correctly identified by Dresser with Acrocephalus dumetorum 

 (Blyth) . In each of the above-mentioned four particulars it 

 agrees with A. dumetorum and disagrees with A. agricola. 



Salicaria turcomana (p. 84). Judging from the length of 

 the first primary, this bird is also an Acrocephalus. The 

 wing-formula — second primary equals -the fourth — restricts
