With regard to the specific name by which this petrel should be 

 distinguished, Mr. G. R. Gray has expressed to me his opinion that it 

 is the species to which that of "hasitata" (being the corrected form 

 of hasitata applied to it by Dr. Kuhl in the year 1820) rightly be- 

 longs ; for although Dr. Kuhl imagined, as did M. Temminck in the 

 extract I have before quoted, that he was describing the subject of 

 Forster's drawing, No. 97, he in reality has given the characteristics 

 of a bird similar to the subject of this paper : and as the names on 

 Forster's drawings were not published until 1844, Dr. KuhPs is the 

 earliest publication of the name. If from the single example whose 

 capture is here recorded, the Procellaria haesitata of Kuhl is to be in- 

 cluded in the list of British birds, it is evident that it must have an 

 English appellation. The ordinary rule that the scientific one should 

 be literally translated, cannot, I think, be applied in this case, nor will 

 it do to take the hint afforded in the French name applied by M. Tem- 

 minck, and coin a meaningless word for the occasion. I should be 

 inclined to call the bird the " Capped Petrel," were it not that it ap- 

 pears, as far as can be ascertained from the two specimens, and the 

 representation of a third, which has been compared on this occasion, 

 that as the bird increases in age, the " cap " grows less, and in very

 bird a shearwater, (Puffinus).
