All the five specimens recorded above have been examined by me. 

 Two were caught on the 19th of October, 1898, and Mr. Hanson 

 thonght that he had procured Pvjfinus hiihli {vide supra, p. 81). He 

 says that the Pvffi.nus {P. kvMi ?) captured on this date were 

 " ashy-grey on the body, but for the rest exactly like Pujflnus 

 major!' 



Three more specimens were obtained on the 24th of October with 

 the mass of Petrels of different kinds obtained on that day. On the 

 25th they were " about in hundreds " (see Hanson App. to Borch- 

 grevink's book, p. 321) {vide supra, p. 81).
