Severtzoff's 'Fauna of Turkestan.' 107 



by General Tseherniaieflf in June 1864, at the taking of Aulje- 

 ata ; and he says that he has altogether seen six specimens, 

 two of which were taken from a nest in an island in the Volga, 

 and one was obtained in Persia. Mr. Severtzoff describes it 

 (p. 114) as follows : — "This species is an intermediate form 

 between F. peregrinus, F. peregrinoides , and F. lunar ius, Schl. 

 With the latter it agrees in having a light brown head, a 

 character distinguishing that species from the two former ; 

 and with these it has some similarity from its long middle 

 toe and short tarsus, the middle toe of F. lanarius being short. 

 In size it is intermediate between F. peregrinus and F. pe- 

 regrinoides. 



The adult female from Aulje-ata measures, length 18" 7 

 inches, extent 402, wing 136, tail 6*5, culmen 1*2, tarsus 

 1*8, middle toe without claw 2'1. 



A young male from Chimkent measures 18*2 inches in 

 length and 39 in extent, and a young male from Sarepta, 

 length 18*2, wing 13*3, tail 6*4, culmen 1*1, tarsus 1*8, mid- 

 dle toe 2 inches.
