THE GIANT PETREL. 95 



We first met with the Giant Petrel in 35° S. lat. on September 21st, when we 

 were in the South Atlantic Ocean. It was in this case the darkest variety of all, with 

 a lemon yellow bill, the variety that may with some truth be called black. Again, on 

 October 22nd, in 45° S. lat, we saw the Ijird in the Southern Indian Ocean, and this 

 example was also black. From that day onward we had one or two with us almost 

 constantly between 45° S. lat., in 51° E., and the ice pack in Gl° S. lat. and 14.3° E., 

 and thence to New Zealand. At the Macquarie Islands we obtained one of the paler 

 grey variety, the lightest in colour that we had seen in coming from the west ; and a 

 few days later, in passing up the western side of the Auckland Islands, we saw Ossifraga 

 in very large numbers, almost all of which seemed to be somewhat small and grey 

 instead of brownish black, as though they were perhaps the hen liirds or the young 

 of a nesting colony. On November 23rd, when we had passed to the north of the 

 Macquarie Islands, we first saw the wholly white variety, and this was in lat. 55°, 

 between 300 and 400 miles to the north of the ice pack we had then just left. 



After leaving New Zealand we went due south to South Victoriii Land, and after 

 cruising eastward along the Great Ice Barrier to long. 152° W., we spent two years in 

 McMurdo Sound, returning thence again to New Zealand by way of the Balleny and 

 Auckland Islands. From New Zealand we made the homeward journey through 

 the Magellan Straits and by the Falkland Islands, and throughout the whole of this part 

 of our voyage to as far north as 33° S. in 20° W. lat. we were accompanied by 

 Ossifraga in greater or lesser numljers. 



The whole distance covered in the Southern Oceans was thus about 22,000 miles, and 

 we were much struck by the way in which the several phases appeared and disappeared 

 from time to time. In the open ocean, and in the more temperate regions throughout 

 September and October, we saw only the largest and Ijlackest birds, in good condition 

 and with clear lemon yellow bills. On approaching the ocean islands of Macquarie 

 and the Aucklands in November we came into a region frequented almost wholly by 

 the smaller and greyer phase or variety, sometimes in great numbers, and these all 

 apparently in full moult, but although we must have seen in all many hundreds, we 

 had met with as yet one only that was wholly white, and that in the rather higher ranges of 

 the temperate latitudes. Between New Zealand and the ice we again saw the grey 

 birds moulting off Campbell Island on December 26th and 27th, and somewhat darker 

 birds on December 29th. In the pack ice we saw one or two of the darker birds, 

 but they became more numerous as we neared the coast at Cape Adare, and one 

 might there constantly see two or three upon the Hoes running along with wide 

 ungainly straddling legs, unable to rise after feeding on some dead Adelie Penguin. 



On January 9th, when we came to Cape Adare, we were surprised to see a collection 

 of Giant Petrels standing on the shore, about a dozen of which were wholly white. 

 In all there must have been two or three dozen birds, the majority of which 

 were black, dark grey and brown, though some had paler heads, and some had 

 heads quite white, with darker bodies. They were less tame and more suspicious
