42 NOVITATES ZOOLORICAE XXV. 1918. 



220. Falco griseiventris Brehra = Falco peregrmus peregrirms* 



Falco griseiventris Brehm, Isis, 1833. p. 778 (" Icli erhielt einen jungen Vogpl im October vom 

 friessnitzer See ; em sehr altes schones Maunchen wurde auf dem Ritfergute des Herrn Baron 

 von Beust zu Nimritz iinweit Neustadt an der Orla am 24. Octol)cr 1S26 gc^chossen "). 



Type: <J ad., Nimritz bei Neustadt, a.d., Orla, 24. x. 1S2G. 



221. Falco leucogenys Brehm = Falco feregrinus cxdidus. 



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

 Deutschlanct und gelit bis nach Egypten " ; but the first mentioned .specimen, on p. 51, is one 

 shot in tlie valley of the Saale on Octol)er 28th, 182r). I therefore eonsiiier this to be the type.jf 



Type : S, " two years old," iu nearly coraplete adult dress, Hummelshain, 

 valley of the Saale, 28. x. 1825. 



222. Cerchneis niflceps Brehm = Falco tinnunculiis tinnuncidus. 



Cerchnels ritfireps Brehm, Vogdjanj. ji. 29 (1855—" In Nordafrika und Siideuroija." Restricted 

 terra typica : Fayoum, Egypt). 



Type : <? ad., Oasi.s of El Fayoum, Egypt, 14. i. 1852. A. E. Brehm leg. 



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

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

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



223. Cerchneis ruficauda Brehm = Falco tinnuncvhis rvpicoheformis. 



Cerchneis ruficauda Brchtn, Yocjcljang. p. 29. No. 10 (1855 — Without indication of locality. Terra 

 typica, Fua, Egypt). 



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



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

 a sjmonym 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 chrysaelos (L.) must be added : 



Aquila sarmatica 



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

 a live bird taken from a nest in the 8amborer Kreis in the Carpathians, and 

 supposed to be a subspecies of A. chrysaetos.'] 



* To p. 1043 of V6q. d. pal. Fauna must be added : The earliest appearance of the name Falco 

 cornicum is Brehm, Ornis. iii. p. 6 (1S27 — " Streicht im Winter in Deutschland herum"). On 

 p. IOCS must be added to the synonyms of Pako rasticolus ruaticolua : Falco umbrinu« Billberg, 

 Vetcnsk. Acad. Handl, 180il. p. 202. Taf. vi. 



t In the synonymy of Falco subbuteo .lubl/ideo must be corrected : Falco hirnndinuin Brehm, 

 Orms, iii. p. 8 (1827— C.ermany). To the synonyms of - Falco columbariua regnlus" (rectius F.c. 

 aeaalon — cf. ISritiah Hirds, ix. p. 5 1) must be added : Falco aubaeaalon Brehm, Ornls, iii. p. S) (1827 

 — " Patrio Islandia. hiome in Germaniara migrant").
