488 Mr. D. A. Bannerraan on the [Ibis, 



Von Thanner records (Orn, Jalirb. 1908, p. 214) two 

 migrants to Tenerife which put in an appearance in the 

 autumn of 1907, and he also shot a bird on the 30th 

 of November, 1908. It is probably this species wliich 

 von Thanner met with in Gran Canaria in February 1909 

 (Orn. Jahrb. 1910, p. 87) and wliich he mentions as having 

 seen constantly in Tenerife (Orn. Jahrb. 1910, p. 101). 



Polatzek apparently did not observe any migration of this 

 species in tiie eastern islands. His notes on the resident 

 birds will be found under F. barbarus (Orn. Jahrb. 1908, 

 p. 102). Polatzek shot several birds in the eastern islands 

 which he forwarded to the Tring Museum, and it was this 

 material which enabled Dr. Hartert to determine to which 

 species these Canarian Peregrines really belonged. These 

 specimens * are here listed : — 



S ad. Fuerteventura. 22 June, 1904. 

 ? ad. Fuerteventura. 27 June, 1902. •

Range beyond the Archipelarjo. 



This small race of the Peregrine breeds in northern 

 Africa, north of the Sahara (Algeria, Tunisia, Egypt, Nubia, 

 and Morocco), extending in the north-west as far south as 

 the southern Atlas range. 



Falco subbuteo. Hobby. 



The Hobby is a Rare Visitor to the Canaries. It is 

 uncertain wdiich race of the Hobby has occurred in the 

 Archipelago. 



It has been recorded on a number of occasions, but with 

 one or two exceptions on very unsatisfactory evidence. 



Berthelot (Orn. Canarienne, p. 6) records Falco subbuteo 

 as rare in all the islands. 



* Since this paper has been in print Dr. Hartert writes to me that 

 he has just received a beautiful female example of this Falcon from 

 Herr von Thanner, who shot the bird at Vilaflor in Tenerife on the 

 28th of September, 1917.
