Expedition to the Eastern Canary Islands. 237 



Ventura, where it has been introduced from the western 

 islands. It is fairly plentiful in the Barranco de la Pena. 

 The examples obtained were all from one locality in 

 Fuerteventura. 



Bill flesh-colour, tip dark ; iris dark hazel ; feet flesh-

This new subspecies, which I have recently described, is 

 confined to the eastern islands of the Canaiy Group. It is 

 easily distinguished from the form found in the western 

 islands by the following characters : — 



1. The upper parts are several shades lighter and lack the 

 particularly rich colouring of the western island form. 



2. The sides and flanks lack the deep chestnut markings 

 and are less boldly streaked with light brown. 



3. The white area on the belly is more extended. 

 Hartert''s Brown Linnet appears to be thinly distributed 



in Fuerteventura, while in Lanzarote it is practically con- 

 fined to the Y alley of Haria, where it is extremely plentiful. 

 A single bird was seen on Graciosa, but in Montana Clara 

 it was not observed. It was again found in Allegranza, 

 where, however, it was scarce and very shy. 



The series collected was chiefly remarkable for the 

 brilliant crimson breasts of the males, especially in the 

 case of those from Lanzarote, although this is not a dis- 

 tinguishing character of the subspecies. 



A large series was obtained from Fuerteventura^ Lanzarote, 

 and Allegranza. 



Bill light horn-colour; iris dark hazel ; feet brown. 

 The following clutches of eggs were taken : — 

 (a) 4 eggs. La Pena, Fuerteventura, 11. v. 13. 

 [h) 3 eggs, Antigua, Fuerteventura, 15. v. 13. (In an 



advanced stage of incubation.)
