There is in the Museum collection an example of this 

 species collected by Emin at Lado ; otherwise these are the 

 first specimens from the Sudan. We see no reason why 

 the African Hobby should not be regarded as a race of the 

 European. One of the birds apparently not fully adult 

 has two well-marked red patches on the sides of the nape. 



Falco concolor. 



Falco concolor Temm. PL Col. 1825, pi. 330 : text not 

 figure : (Senegal errore !) coasts of Barbary ; Reich w. V. A. 

 i. p. 629. 



An example of this species is believed to liave been 

 obtained by Hemprich and Ehrenberg at Ambukol in 

 Dongola, and was described by them as Falco schistaceus. 

 According to Zedlitz, J. f. O. 1914, p. 674, this is a synonym 

 of F. concolor. We know of no other Sudanese examples.
