IINNEAN GENUS FALCO. 



611 



The eighth variety, is the Red Indian Falcon ; F. ruber 



Indicus. 



Falco ruber Indicus, Briss. * 



From the description given by Brissok, the 

 male appears greatly to resemble the adult Pere- 

 grine Falcon of Europe. The upper parts of the 

 plumage are nearly black ; of the female cine-- 

 reous brown. 



The ninth variety, is the Spotted-winced Falcon : ^- (com.) 

 Talco maculatuSy Briss. 



This bird shews plainly the transition to the 

 adult Peregrine Falcon f . The upper plumage is 

 brown ; the rump and tail cinereous, with trans- 

 verse black bars; and Brisson observes, In 

 utroque capitis latere majuscula, est macula longi- 

 tudinalis fiigra, infra oculos orta, et ad colli ex- 

 » ortum usque protensa and again, " Alae, su- 

 pra lineis transversis, nigricantibjis variegatse.'* 

 Latham enumerates this among the varieties of 

 the Common Falcon ; but he seems to have been 

 aware of its relation to the Peregrine Falcon, as it 

 is again given as a variety of that species, and the 

 same synonyms are referred to. Buffon consider- 

 ed it as the young of the following variety. 



* The F, ruber Indicus is conjectured by BecksTein to be a 

 distinct species. The same opinion was adopted by Buffon. 



+ I find that Beckstein also considers it as the Peregrine 

 Falcon.
