Eapedition to the Eastern Canary Islands. 269 



We did not discover it on any of the other outlying islets 

 visited. Notes on the habits of this Petrel are given in 

 Part I, (vide supra). 



A large series of birds was procured from Montana 

 Clara, 



Bill black ; iris dark hazel ; feet pale flesh-colour, outer 

 toe and webs dusky. 



Eighteen eggs were obtained_, pure M'hite in colour with 

 an unglossed surface. 



The measurements of 14 of this series are : 45*5 x 33^ 

 42x30-.9, 44x31^ 43x30, 43x32-5, 44x31-5, 415 x 

 30, 41-5 X 28-5, 41-5 x 31, 42 x 31, 43 x 31, 42 x 30, 43 x 30-5, 

 42 X 31 mm.

Although all of the above species are from time to time 

 found in the Canary Island seas, not one of them was met 

 with during the Expedition. In the first part of this paper 

 (for pages see above) I discussed the likelihood of the first 

 three of the above species ever having bred in the Canary 

 Archipelago. I am of opinion that Ptfffijius p. pnffiniis has 

 ce.ised to breed in the group, or rather that we cannot now 

 consider it to be a breeding bird until fresh satisfactory 

 evidence is forthcoming. 



There is no evidence whatsoever that Pelagodroma m. 

 hypoleuca or Oceanodroma castro has ever been known to 

 breed on any of the Canary Islands proper. (Both species 

 breed on the Salvage Islands, distant 100 miles from the 

 nearest point.) 



As to Oceanodroma leucorrhoa I'Vieill.), we are told by
