220. Falco griseiventris Brehm = Falco peregrinus peregrinus* 



Falco griseiventris Brehm, Ms, 1833. p. 778 (" loh erhielt einen jungen Vogel im October vom 

 friessnitzer See ; ein sehr altes schones Maunchen wurde auf dem Rittergute des Herrn Baron 

 von Beust zu Nimritz iinweit Neustadt an der Orla am 24. October 1826 gesohossen "). 



Type : 3 ad., Nimritz bei Neustadt, a.d., Orla, 24. x. 1826. 



221. Falco leucogenys Brehm = Falco peregrinus calidus. 



Falco leucogenys Brehm, Naumannia, 1854. pp. 51. 60. (On page 61 it is said : " Er bewohnt 

 Deutschland und geht bis naoh Egypten"; but the first mentioned specimen, on p. 51, is one 

 shot in the valley of the Saale on October 28th, 1826. I therefore consider this to be the type.)t 



Type : ^, " two years old," in nearly complete adult dress, Hummelshain, 

 valley of the Saale, 28. x. 1825. 



222. Cercbneis ruficeps Brehm = Falco tinnunculus tinnunciilvs. 

 Cerchneis ru/iceps Brehm, Vogelfang, p. 29 (1855—" In Nordafrika und Siideuropa." Restricted 

 terra typica : Fayoum, Egypt). 



Type : <? ad., Oasis of El Fayoum, Egypt, 14.1. 1852. A. E. Brehm leg. 



We are still in uncertainty about the Egyptian Kestrels, but it seems to 

 me. that F. tinnunculus tinnunculus is a winter visitor, while the form which 

 nests in Egypt ( ? or perhaps only in Nubia) is rupicolaeformis. 



223. Cerchneis ruilcauda Brehm = Falco tinnunculus rupicolaeformis. 



Cerchneis rufieauda Brehm, Vogelfang, p. 29. No. 10 (1855 — Without indication of locality. Terra 

 typica, Fua, Egypt). 



Type : <J Fua, Nile Delta, 4. xi. 1849. A. E. Brehm leg. 



In Vog. pal. Fauna, p. 1083, I have placed the name Cerchneis rufieauda as 

 a synonym of Falco tinn. tinnunculus ; but as the only fairly old male in the 

 collection (the type) agrees with F. t. rupicolaeformis, the name is better placed 

 among the synonyms of the latter. The red head and red tail are of course not 

 a specific character ; it is found in many younger males and sometimes in fairly 

 old, though apparently not in quite adult males. Besides the type there is 

 only an adult female in very worn plumage and a juvenile male, both from 

 Egypt, in the collection. 



[To the synonyms of Aquila chrysaetos chrysaetos (L.) must be added : 



Aquila sarmatica 



Siemonuszowa-Pietruski, Allg. D. Naturh. Zeitung, 1847. p. 44, described from 

 a live bird taken from a nest in the Samborer Kreis in the Carpathians, and 

 supposed to be a subspecies of A. chrysaetos.] 



* To p. 1043 of Vog. d. pal. Fauna must be added : The earliest appearance of the name Falco 

 cornicum is Brehm, Ornia, iii. p. 6 (1827 — " Streioht im Winter in Deutschland herum"). On 

 p. 1068 must be added to thq synonyms of Falco ruaticolua ruaticolua . Falco umbrinus Billberg, 

 Vetenak. Acad. Handl. 1809. p. 202. Taf. vi. 



f In the sjmonymy of Falco aubbuteo subbuteo must be corrected : Falco Mrundinum Brehm, 

 Ornia, iii. p. 8 (1827 — Germany). To the synonyms of "Falco columbariua regulus" (rectiua F. c. 

 aeaalon — of. Britiah Birda, ix. p. 5 !) must be added : Falco aubaeaalon Brehm, Ornia, iii. p. 9 (1827 

 — " Patria Islandia, hieme in Germaniam migrant").
