Range in the Cape Verde Islands. 

 Branca, Brava, Baza, St. Vincent. 



P. k. ediuardsi was originally described by Oustalet from 

 the island of Branca ; since then it has been found on Brava 

 and Raza by Boyd Alexander as well as on the first-mentioned 

 island. 



Becently I have received an adult male which was captured 

 in Salamanja Bay^ St. Vincent, on the 27th of October, 

 1913. I have not been able to discover whether this Shear- 

 water breeds on St. Vincent. Probably it does noi. 



The only islands upon which P. k. edwardsi has actually 

 been found nesting are the islands of Brava and Raza, 

 which, as Boyd Alexander remarks, may be considered the 

 true home of this species. It doubtless will also be 

 discovered breeding on Branca. 



The first eggs are laid in September, as far as we know. 



Alexander, in his list of the Birds of Brava, wrote that 

 "On March 7th, while in the vicinity of the harbour, two 

 boys brought us four specimens of this new Shearwater. 

 They had obtained them from the holes oE a rock out at sea 

 and along the coast. We also noticed a few individuals on 

 our way to Ronibos Islands flying over the water, but to our 

 surprise none inhabited the rocks of these islands. They 

 appear to confine their habitat to the Brava coast. "VYe met 

 with this species again on Raza, where it is much more 

 numerous." The four specimens obtained on Brava are in 

 the British Museum, 



Leonardo Fea, who visited Brava in July and August 

 1898^ obtained specimens of P. k. edwardsi on the northern
