After Chizcehis zoniorus slxjukl be inserted Cory- 

 thaixoides leacogaster, of which a specimen has been 

 sent home by Mr. King. It was collected at Ikoto 

 near Torit in south-east Mongalla, 17 Feb. 1918, and is 

 an addition to the Sudanese list. 



Ibis, 1919, p. 663. Irrisor erythrorhynchus. The genus /rrisor 

 must be rej^laced by Phamiculus Jaroeki, 1821 (c/. Aus- 

 tral Avian Record, iii. No. 6, p. 146), and the family 

 Irrisoridse must become Phceniculidse. 



Ibis, 1919, p. 668. Among the Alcedinida) should be inserted a 

 race of Alcedo ispida. Mr. Butler informs us that it 

 occurs commonly in the harbour at Port Sudan, and 

 that a specimen obtained by him was given to the 

 Gordon College Museum. Mr. Butler refers the 

 specimen to A. i. 'pcdlida Brehm. 



Ibis, 1919, p. 675. Palceornis krameri. Palceornis should be 

 Fsittacula, vide Mathews, Birds of Australia, vi. p. 169. 



Ibis, 1919, pp. 686-7. For Tinnuncidus read Gerchneis. Vide

 rapax raptor. The name Falco [Aquila) albicans Riipp. 

 is preoccupied by Falco albicans Gmelin, S. N. i. p. 276, 

 as was pointed out to me by Mr. Iredale. The next 

 available name appears to be Aquila raptor A. E. Brehm, 

 Naumannia, 1855, p. 13 : Blue and White Niles, of 

 which the type is at Tring. 



With regard to the Eagles collected by the Chapman- 

 Lynes expedition in the Red Sea Province, Mr. Abel 

 Chapman has suggested that at least one of the Eagles 

 we have called A. r. albicans differs considerably from 

 the others, notably by the length of its legs as com- 

 pared with the shortness of its tail. It was collected 

 at Erkowit and certainly is unlike most of the A. r.
