during a Voyage to New Zealand. 189 



In this way we can easily account for Diomedea exulans, D. 

 chlororhynchus, P. gigantea, and the present species having 

 been found in European seas. These birds were kept in a large 

 tub and fed with salt pork. Albatroses are often brought alive 

 into the Australian ports. From April 26th Cape-Pigeons fol- 

 lowed us to Cape Brett, New Zealand, coming within a few 

 miles of the land. They were most numerous about June 3nd, 

 in lat. 44° 27' S., long. 150° 12' E., on which date there were 

 about sixty round the ship. 



Prion vittatus (Gmel.). First seen April 7th, lat. 36° S., 

 long. 17° 22' W., and they accompanied us during the re- 

 mainder of the voyage, sometimes being very numerous. On 

 May 13th, lat. 38° 30' S., long. 70° 50' E., I estimated that 

 there were more than a thousand round the ship. In my 

 last paper (Ibis, 1865, p. 288) I was in error in saying that 

 this bird never settles on the water ; I have occasionally seen 

 it do so for a few minutes. 



Several species may be here included under this name, as I 

 could not obtain any specimens ; but I was not able to see any 

 difference, and believe that P. vittatus is the commonest of the 

 Prions. 



PuFFiNus AssiMiLis, Gould. On May 7th and 8th, when 

 about three hundred miles north of the Crozets Islands, we 

 saw six or eight of these birds : we did not see them again 

 during the voyage, except one on May 9th, in lat. 45° 5' S., 

 long. 132° 30' E. 



Thalassidroma melanogaster, Gould. First seen April 

 6th, lat. 35° 32' S., long. 18° 46' W., and remained with us 

 until May 20th, lat. 42° 23' S. long. 97° 40' E. ; after this it 

 was not seen until June 3rd, lat. 42° 51' S., long. 155° 17' E., 

 whence it accompanied us nearly to New Zealand. From 

 April 25th, lat. 38° S., long. 21° E, until May 5th, lat. 41° 9' S., 

 long. 43° 7' E., these birds were very numerous, often forty or 

 more together. I am not sure that I saw any T. leucogaster, 

 Gould, although there were many T. melanogaster with very few 

 dark feathers on their bellies, and every connecting link between 

 these and the true T. melanogaster. T. leucogaster may, I
