ill AToya. Huge flocks were seen at San INIateo in February 

 (1912), where tliey were feeding in the fields literally in 

 liuudreds. In the south I found them to be decidedly 

 scarce. 



The female shot on April 5th contained well-developed 

 eggs in the ovary.

Messrs. Hartert and Kleinschmidt have, I consider, 

 separated the Raven of the Canary Islands from Corvus 

 c. iincjitanus on somewhat slight grounds. 



The following remarks on this subspecies appeared in the 

 Nov. Zool. 1901, p. 326 :— 



" We find that the form from the Canaries is distinguished 

 from C. c. tinyitunus .... by its beak, which is longer, 

 straighter, and weaker (where it is equally strong it is longer, 

 where it is equally long it is weaker), and by the edges of 

 the feathers, which are more Co/«a:-like and less closed. 

 As a rule, but not always, the feathers of the throat are 

 longer." 



On comparing examples from Gran Canaria and Tenerife 

 with the small series of C. c. tingitanus in the British 

 Museum, it struck nie that the Ijill in birds from Gran 

 ( Janaria Avas, if anything, heavier than in examples of C. c. 

 tingitanus. This ap})cars to be in direct opposition to the 

 conclusions which Dr. Hartert has arrived at. When a very 

 much larger series from Gran Canaria is available some 

 slight differences may possil)ly be found to be constant; but 

 as the description of C. c. canariensis does not apply to my 

 specimens from Gran Canaria, 1 prefer to unite these birds 

 with C. c. tingitanus, the resident species on the N.W. coast 

 of Africa.
