Bill black, the tip yellow. 



The younger birds are recognised by their black bill and browner 

 plumage, the whole head and sides of face being leaden grey, and the 

 throat paler grey. There is no trace of the yellow band along the 

 culm en, but a slightly paler appearance at the base of the lower 

 mandible; otherwise the bill is black. In the youngest example 

 there are indications of lighter brown edges to the feathers of the 

 mantle. The white head and throat are only gradually assumed and 

 are evidently the signs of very old birds. In the majority of 

 specimens these parts are of a beautiful dove-grey. 



This species is of wide distribution in the Southern oceans. Mr. 

 Hanson records the first capture of the Albatros, with " black-and- 

 yellow bill," on the 24th of October, 1898 {antea, p. 81). Two more 

 were caught on the 2nd of November (p. 82), but were apparently 

 not preserved, and on the 6th of the same month four " black-billed " 

 specimens were obtained. This Albatros followed the ship to 

 Tasmania, and is recorded nearly every day in Mr. Hanson's Diary. 

 After leaving Tasmania, it was seen on the 26th of December {antea, 

 p. 83) and is again recorded as occurring in the open sea, after the 

 ship emerged from the ice-pack in February (p. 93).
