cliffs on the north-west, and on my last day in the island 

 I obtained a splendid view of the bird at close quarters. I 

 had been sitting Avaiting for Swifts in the rochy cove seen in 

 the foreground of the accompanying photo (Ph III. fig. 2), 

 when two Rock Pigeons darted out from a crevice overhead 

 and flew out to sea; hardly had. they left the shelter of 

 the overhanging cliff when a Falcon dashed down upon them 

 from above; the Pigeons, flying at a great speed, described 

 a semicircle over the sea_, and being soon caught up by their 

 speedy foe, headed again for the cliffs. All three eventually 

 passed over me within five yards of my head. There is little 

 doubt that the bird was a fine example of Falco pei^egrinus 

 pelegrinoides. 



7. Tinnunculus tinnunculus dacotice. — Kestrels w^re seen on 

 several occasions but were not plentiful, They probably 

 breed on the island. 



8. Pandion h. lialiaetus. — A pair of Ospreys is resident 

 on the island, and could be seen every day soaring high over 

 the sea. 



9. Neophron percnopterus. — -Two or three Egyptian Vul- 

 tures were seen on different occasions. They may possibly 

 nest on the high cliffs on the north-west of the island 

 (PL III. fig. 2). 



10. Thalassidroma pelagica. — There is no record of a 

 Storm-Petrel having been taken on land in any of the Canary 

 Islands to my knowledge. I therefore experienced no little 

 surprise when a male specimen was caught and brought to 

 me by the fisherman who had remained with me on Montana 

 Clara. This man graphically described to me how^ having 

 entered a large cave, he had pushed his almond rod into a 

 hole, when out flew the "Alma Mestre" into his face ; he 

 had. knocked the bird down and brought it to me in triumph. 

 An examination of this specimen showed the testes to be 

 enormously developed, Avith every indication that the bird 

 was breeding. Unfortunately the cave could only be visited 

 once again before my final departure from the island, and I
