A Letter was read, addressed by Capt. P. P. King, R.N., Corr. 

 Memb. Z.S., to W. J. Broderip, Esq., and dated New South Wales, 

 April 13, 1834. It gave some account of the Oceanic Birds ob- 

 served during the late voyage of the -miter from Europe to New 

 South Wales, and more particularly of those of the genus Diomedea, 

 Linn. 



" From the meridian of the island of Tristan d'Acunha to that of 

 the island of St. Paul's, on about the parallel of 40° of south lati- 

 tude, we were daily surrounded by a multitude of oceanic birds. — Of 

 the Petrel tribe the Cape Pigeon, Procellaria Capensis, Linn., was 

 most abundant ; but the Proc. vittata (vel ccerulea) frequently was 

 observed ; as was also a small black Petrel which I do not recollect 

 to have before seen. 



" Of the genus Diomedea the species which I regarded as the spa- 

 dicea, chlororhynchos and fuliginosa of Authors, were the most re- 

 markable. Near Tristan d'Acunha the first (Diom. spadicea) most 

 abounded : between the Cape and the longitude of 30° East the 

 second {Diom. chlororhynchos) became more numerous : and in the 

 neighbourhood of St. Paul's their place was supplied by the Diom. fu- 

 liginosa. Where one species abounded, the others were only occa- 

 sionally seen ; from which it may be inferred that each species breeds 

 in distinct haunts. Occasionally two or three varieties of the Diom.
