This, 1918, p. 470. Passer jagoevsis cordofanicus. Lord Roth- 

 schild has kindly sent us two examples of the true 

 P. j. cordofanicus collected by Baron von Miiller's 

 exjiedition in 1848 in Kordofan, and they differ 

 most strikingly from the Mongalla birds to which we 

 had applied that name. The only characters we need 

 note are that the upper surface is bright rufous chestnut 

 instead of brown or grey-brown, and the dark streaks 

 on the mantle are fewer in number. Oui' birds must 

 then be called Passer jagoensis shelleyi {Passer shelleyi 

 Sharpe, Ibis, 1891, p. 256: Lado), though it is worth 

 remai^king that the type is a very bright-coloured bird 

 compared with ours. 



Ibis, 1918, p. 470. After Passer domesticus arhoreus should be 

 inserted Passer hisjxaiiolensis, which reaches as far 

 south as the Dongola Province in the Nile Valley, and 

 has even been recorded from the Blue Nile. 



Ibis, 1918, p. 611. Motacilla, vidua Sundev. is antedated by 

 Motacilla aguini]) Dumont, Diet. Sci. Nat. xxi. 1821, 

 p. 226, ex Levaillant : " Orange River." Cf. Austral 

 Avian Record, iii. No. 1, p. 14. 



Ibis, 1918, p. 612. Motacilla Jlava melanocephala should be 

 Motacilla flava feldegg Michahelles, Isis, 1830, p. 812 : 

 Dalmatia, as Lichtenstein's name is preoccupied by 

 Motacilla tnelanocephala of Gnielin, 1789. The Yellow 

 Wagtails would be treated of better under the separate 

 generic or subgeneric title Budytes, 



Ibis, 1918, p. 656. Cisticola erytkroj^s roseires. This form is 

 probably identical with Cisticola nilotica Madarasz, 

 Ann. Mus. Nat. Hung. xii. 1914, p. 591 : Blue Nile, 

 lat. 13° N. If so, the bird must be known as 

 C. erythrops nilotica Madarasz. 



Ibis, 1918, p. 676. Prinia mistacea mistacea. Prinia pallescens 

 Madarasz, Ann. Mus. Nat. Hung. xii. 1914, p. 593 : 

 Luieza, Binder river, is probably only a worn example 

 of P. m. mistacea. 



Ibis, 1918, pp. 669-670. Troglodytes micrurus Riippell, Neue 

 Wirb. p. 109, pi. 41, was published in 1836, thus ante- 

 dating Sylvietta hrachyura of Lafresnaye, 1839, and 

 therefore the name for the group should be Sylvietta 

 micrura, not hrachyura.
