description of the Swaffham bird ; and I am indebted to Mr. Stevenson for the loan of a drawing 

 by Wolf of this bird, from which my Plate is taken. I am also indebted to Professor Newton 

 for much valuable assistance in working out the synonymy of this species. 



I may here mention that Mr. F. A. Ober lately observed a bird in Dominica called the 

 " Diablotin," which Professor Baird believes to be Prion caribbasus, but which, it appears to me, 

 must be the Capped Petrel. Mr. Ober, however, did not obtain a specimen.
