At page 125 Dr. Severtzoff writes as follows : — "Turkestan 

 specimens of this bird differ so much in the form of the bill, 

 that I deem it best to refer those with the broad bill to Hy- 

 polais, under the name of H. graminis, and those with the 

 narrow bill I call Phyllopneuste intermedia, as being an inter- 

 mediate form between the former species and P. superciliosa 

 (Cab.), as my Ficedula middendorffi is intermediate between 

 Hypolais and Phyllopneuste. The descriptions of these two 

 forms are as follows : — 



" a. var. intermedia. Bill narrow at the base, and at the nos- 

 tril its breadth is equal to its height ; one third of the bill is 

 broader than it is high, and two thirds narrower ; thus it is 

 awl-shaped ; quills 3 = ] >5>6>2>7; first primary short, 

 being twice as long as the coverts ; tail even. Length 4" 8'"- 

 4" 9'", extent 7" 2'", wing 2" 4'", tail 1" 9^", tarsus 7\"', mid- 

 dle toe 4'", culmen 3^", breadth of bill at the nostril 1'". 



'' b. var. hypolania {Hypolais graminis, nob.). The bill nar- 

 rows gradually from the base to the point, as in Hypolais, 

 being narrower than in that group, but broader than in true 

 Phyllopneuste ; the wing is blunt, first primary short, nearly 

 twice as long as the coverts, 3 = 4>5>6>7>2>8, or 3 = 4, 

 2 = 7, or the 4th the longest, 3 = 5 >7>2>8, or 4=5, 3=6, 

 2=9; the latter form, with a very blunt wing, was a spring-
