. Expedition to the Eastern Canary Islands. 265 



Savile Reid (Ibis, 1888, p. 80), and Meade-Waldo (Ibis, 1890, 

 p. 4-37 ; 1893, p. 207) all used for tliis Shearwater the name 

 of Picffinus obscurus, but P. obscnrus Gxn., according to 

 Godman, ranges from the islands of the Pacific Ocean to 

 the Mascarene Islands, and therefore cannot be used for the 

 Atlantic form of tliis Shearwater. 



In ' The Ibis ' for 1890, Ogilvie-Grant, writing- on the birds 

 obtained at Madeira, Deserta Grande, and Porto Santo, 

 again refers to this Shearwater a.^ P iiffinus obscui'us, dlt\\o\x^h. 

 he corrects this statement later in ' The Ibis ' for 1896, p. 50, 

 wliere this and the bird from the Salvage Islands is said to 

 be Puffinus assimilis Gould. In this decision he is followed 

 by Boyd Alexander, who designates Puffinus assimilis as 

 breeding in the Cape Verde Islands (Ibis, 1898, p. 98). 

 Rothschild and Haitert pointed out (Nov. Zool. 1899, vi. 

 p. 196), that the birds from| Madeira are not the same as 

 P. 0. assimilis from the Australian and New Zealand Seas. 

 They therefore adopted (with reserve) the name Pufinus 

 obscurus bailloni Bonap., noting, however, that perhaps this 

 Shearwater of the Atlantides required to be renamed. 

 Hartert, however, keeps up this name in the Nov. Zool. 

 1901, p. 332, and 1905, p. 99. 



Godman, in the ' Monograph of the Petrels,^ 1908, p. 138, 

 follows Rothschild and Hartert in calling this species 

 Puffinus bailloni, but points out that the name bailloni was 

 given by Bonaparte to a bird from Mauritius (" Isle de 

 France ") and therefore becomes synonymous with Puffinus 

 obscurus Gm. He does not, however, give a new name to 

 the north-east Atlantic form, 



Allen, reviewing Godraan's 'Monograph of the Petrels' 

 (Auk, 1908, p. 339), seeing that Godman had noted the 

 differences between the Madeiran and Mauritius Shearwater, 

 named the former Puffinus goclnani without seeing the 

 specimens. Rothschild and Hartert, having discovered that 

 the north Atlantic bird differed from that from the Sey- 

 chelles, came back to the question and, ignorant of Allen's 

 action, named the north-east Atlantic bird Puffinus obscurus
