493 Mr. D. A. Bannerman on the Distribution of 



observer, Padre Schmitz, and many other ornithologists, on 

 every member of the group. 



The bird was originally described in 1828 bj^ Jardine & 

 Selby from one of the islands of the Madeira Group — the 

 following year Heineken named the same species Procellaria 

 anjinho and gave an account of the bird in ' Brewster^s 

 Journal.' In this he states that Bulwer's Petrel arrives 

 in this group in February and March. In June it begins 

 to lay, and in July the young ai^e hatched, while none are 

 seen after September until the following year. 



Padre Schmitz apparently does not agree that the bird 

 arrives as early as February, for on May 23, 1907, he writes 

 in his diary, "From Porto Santo I receive exceptionally early 

 B. bulweri, which does not arrive, as a rule, until the end 

 of the breeding-season of P. o. bailloui ( = P. a. baroli), which 

 is not yet over " ^. 



Harcourt found it very numerous on the Deserta Islands ; 

 Ogilvie-Grant caught a number of adult birds on Deserta 

 Grande on May 4, but they had not yet begun to breed. 

 Godman found " considerable numbers breeding on the 

 Small Deserta " in June, but does not record the actual date 

 of his visit. 



We may safely assert that Bulwer's Petrel usually makes 

 its appearance in the Madeira Seas early in May and 

 apparently commences at once to breed. During June 

 nesting is in full swing, and in July many young-in-down 

 may be found. The season continues through August and 

 into September, after which -month the birds apparently 

 disappear until the following spring. 



Breeding range in the Salvage Islands. 

 Mr. Ogilvie-Grant was too early in his visit to these 

 islands (from the 24th to the 29th of April) to find the eggs 

 of this Petrel. The birds, however, had arrived on Q^-eat 

 SalvEge, and many were captured every night. They probably 

 breed there in May and June, as is the case in the Madeira 



* The majority of P. a. haroU have finished breeding iu the Madeira 

 Group by the middle of May. [D. A. B.]
