from the colony of Natal. 131 



specimens of Circa'dtus zonurus fioux Bissao, preserved in the 

 Norwich Museum, and referred to in the foot-note ah-cady 

 quoted, one agrees very accurately with Dr. HeugUu's plate; 

 but the other, though apparently not specifically distinct, differs 

 in colour, — the throat and chest being white, the abdomen and 

 thighs whitish brown, with no appearance of transverse bars, 

 and the tail also of a pale dingy brown, showing no trace of the 

 transverse bar across the middle, but only of that across the 

 lower part. The plumage in this specimen is much faded and 

 worn, apparently by the action of the sun and air. 



The Norwich Museum also contains two other Circaeti from 

 Bissao, which a])pear to me to be examples of Circa'etus ijaUicus, 

 though they differ from any other specimens of that species 

 which I have seen in having the whole of the under parts of a 

 rusty-brown colour, resembling, in that respect, some of the im- 

 mature specimens of Circa'dtus thoracicus. — J. II. G.] 



131. Falco pehegkinus, Linn. Peregrine Falcon. 



[Sent to Mr. Stevens by Mr. Gueinzius : no ticket attached; 

 but a{)parently a female bird in nearly adult plumage. This is 

 the only specimen of the true Peregrine Falcon which has come 

 into my hands from any locality south of the Equator. — J, II. G.] 



132. Falco minor, Bp. Rev. de Zool. 1850, p. 484. South 

 African Peregrinoid Falcon. 



[This specimen was also sent to Mr. Stevens by Mr. Gueinzius. 

 The following ticket was attached to it : — " $ . Irides dark." 



The plumage of this specimen bears considerable resemblance 

 to that of the Falco melauoijeays, Gould, of Australia, especially 

 in the narrowness of the spaces between the transverse abdo- 

 minal bars. Its size is about that of the male Peregrine. As 

 this Falcon is but little known to naturalists, I may, perhaps, 

 be permitted to refer the readers of ' The Ibis ' to some interest- 

 ing remarks respecting it, and especially as to the differences 

 between this species and the small Falcon of North Africa 

 [Falco tunetanus of Aldrovandus, F. peregrinoides of Temmiuck, 

 PI. Col. 479, and F. burharus of Mr. Salvin, in ' The Ibis,' 1859, 

 pi. 6), which are contained in pp. 29 and 30 of the ' Traitc de 

 Fauconnerie' by Professor Schlegel, who has there called this 

 bird Falco communis minor. — J. H. G.]
