6b LANNER FALCON. 



name has been given to the Peregrine, the Ger-Falcon, 

 the Sacer, and other birds, even by systematic writers. 

 We are indebted to M. Schlegel for applying the right 

 name to the right bird, and for drawing that distinc- 

 tion between this and the preceding species, which 

 must in future prevent any mistake. 



There are few naturalists who have correctly distin- 

 guished this bird. Schlegel considers that Naumann 

 and Buffon have represented the true Lanner, killed 

 at the beginning of the first moult, but they have 

 taken it for the young of the Peregrine. The Lanner 

 of Linnaeus and Nilsson he thinks is identical with the 

 Ger-Falcon of Norway. The bird described by Pennant 

 as this species, appears to be the young of the 

 Peregrine. Schlegel himself, in his "Zoology," described 

 as new to science a Falcon under the name of Falco 

 feldeggii, which upon more attentive examination he 

 became convinced was no other than the bird known 

 to Falconers, and first described by Belon, so long 

 back as 1555, in his "Hist, de la Nat. des Oiseaux," 

 as the true Lanner, the subject of the present notice. 



There is a specimen in the Museum of Mayence, 

 of a young bird, killed at Hanau, which has consid- 

 erable resemblance to the Falco biarmicus of Temminck, 

 but is distinguished by the colour as well as by 

 the first quill feather being longer in the Lanner. The 

 only Falcon for which it can be mistaken is the Pere- 

 grine, and here the likeness is considerable, but it may 

 be readily distinguished by the greater proportionate 

 length of its tail, by the toes being shorter, by the 

 moustache (the dark longitudinal mark on the side of 

 the head and neck) being less, by the feathers of the 

 inferior parts being larger and softer,' by the reddish 

 colour of the nape, and by the absence of the
