easily distinguished from the Dusky Petrel, which is another inha- 

 bitant of the Dezertas, by its superior size, and by the colour of its 

 feet. In the Dusky Petrel the feet are bluish ash-colour, and in the 

 Manks Shearwater flesh-colour ; in the Dusky Petrel all the secre- 

 tions are green, and in the Manks Shearwater yellow. The Dusky 

 Petrel is a very tame bird, and will live upon almost anything ; it 

 runs along the ground on its belly, and uses its curious- shaped bill 

 in climbing up the rocks. 



The Angel Petrel of Heineken has the tail slightly forked, and 

 differs from the other smaller Petrels in having no white about the 

 rump or flanks ; it is entirely uniform black ; it is very common on 

 the Dezerta islands; when approached it emits a highly offensive 

 matter. 



The Bulwer's Petrel, as described by Sir Wm. Jardinef, I never 

 saw at Madeira, nor have I ever met with any one that has seen it 

 there. Sir "Wm. Jardine says, "it is easily distinguished from any 

 other, by having the two centre tail-feathers elongated, as in the genus 

 Lestris, and not even or forked, Hke the other Petrels." It is pro- 

 bably identical with the Angel Petrel. 



There is another Petrel, called by the natives " Roque de Castro," 

 pronounced "Roque de Crasto," which differs from any I have ever 

 seen described; it approaches perhaps nearer to Leach's Petrel than 

 any other, though the shape of the bill alone is sufficient to separate 

 it from that species. It is common on the Dezerta islands, where it 

 breeds, though it is by no means so abundant as the Angel Petrel.
