4-31. Thalassidroma PELAGiCA (Linn.). 



This bird replaced T. melanogaster when we were between 

 the latitudes of the Zambesi and Zanzibar, the former of these 

 places being, I suspect, its extreme southern range, as Mr. 

 Layard does not notice it in his work. 



-4- 32. Procellaria gigantea, Gmel. 



The Giant-Petrel was not uncommon from the Cape to lat. 

 27° S., where it left us. At night, when hovering round the 

 ship, it emits the most diabolical sound, between a croak and a 

 scream ; this considerably startles the mariner, who does not 

 know to what it is attributable, especially as it is often sounded 

 within a few feet of his ear. 



33. Procellaria glacialotdes, A. Smith. 



Only one came under my observation ; his habits appeared 

 very similar to those of the preceding species. 



34. Procellaria capensis, Linn. 



Decidedly the commonest of the large Petrels in these seas. 

 I think their breeding- place is at present unknown.

4- 37. Diomedea exulans, Linn. 



The Wandering Albatros is seldom seen near land. When 

 well at sea we were visited by them, but I never saw them to 

 the northward of the 27th parallel of south latitude. I am 

 inclined to doubt whether this bird ever visits the northern 

 hemisphere, notwithstanding that three or four specimens are 

 recorded as having been obtained in Europe (though I can hear 

 of none later than 1833)*; but, I believe, they have no more 



* [Only two of these reported occurrences can, we think, be accepted 

 as free from doubt : — that near Dieppe, about the year 1830, the head 

 and feet of the bird being in the collection of the late M. Hardy (I)egl. Orn. 

 Eur. ii. p. 357) ; and that near Antwerp in 1833, when the bird was seen 

 by Drapiez (Isis, ISo-'i, p. 2o0). All the other notices possibly refer to
