Birds inhabiting the Southern Ocean. 287 



Procellaria glacialoides, Smith. Thalassoeca glacialoides, 

 Bp. Consp. Av. ii. p. 191. Gould, B. Austral, vii. pi. 48. Silvery- 

 grey Petrel. 



Back, wings, head, and tail ash-grey, with a rudely-shaped 

 circular ring of black near the tip of each wing ; rest of the body 

 white. Not common, and not seen by me east of the Cape of 

 Good Hope. Not found on the Prince Edward Islands nor 

 Kerguelen's Land. I presume that this is the bird figured by 

 Gould, although neither he nor Dr. Smith mention the dark 

 mark on each wing. 



Procellaria mollis, Gould, B. Austral, vii. pi. 50. Cooki- 

 laria mollis, Bp. Consp. Av. ii. p. 190. Soft-plumaged Petrel. 



Not found on the Prince Edward Islands nor on Kerguelen's 

 Land. They fly well, with their wings a little bent back, like a 

 Sandpiper. I think it probable that this bird will prove to be 

 the young of Procellaria cooki, Gray. 



Daption capensis (Linn.) ; Gould, B. Austral, vii. pi. 53. 

 Pintado-Petrel. 



Across the wings three feet, length fifteen inches. When 

 caught and brought on board ship it throws up from its mouth, 

 as soon as touched, a quantity of red, strong-smelling oil — not 

 as a means of ofi'ence or defence, but simply from fright. Mr. 

 Gould states that when irritated it ejects an oily fluid from its 

 nostrils, but this I have never observed. They cannot rise from 

 the deck, but run along with outstretched wings. Their cry is 

 like the sound made by drawing a piece of iron across a large- 

 toothed comb — "cac, cac, cac-cac, cac," the third being pro- 

 nounced the quickest. It is called " Cape-Pigeon " by sailors. 

 Curiously enough, although this bird is by far the commonest 

 of all the Petrels, and is so distinct in plumage that no one can 

 mistake it, yet its breeding-place is, I believe, not known with 

 certainty. In Mr. Gould^s account of the bird I find ''it is said to 

 breed in Tristan d'Acunha,'^ but Captain Carmichael does not 

 mention it. Mr. Darwin (Zoology of the Voyage of the ' Beagle') 

 was informed that the sealers know of no other place where it 

 resorts to breed but the island of South Georgia; and it cer- 

 tainly is not found on the Prince Edward Islands nor Kerguelen's
