Diomedea exulans. 
WANDERING ALBATROSS. 
The following notes apply to this species and its sub-species. 
A. —The immature male from Antipodes Islands is dark brown all over, 
wings darker; tail-feathers dark brown with white bases; under wing-lining 
white; axillaries white, some few feathers with faint vermiculations; chin, 
throat and sides of face white, which colour extends above and behind the eye, 
with a white line over the bill, thus giving a spectacled and white bib appearance. 
B. —'Female, older (Campbell Island), very like the above, lighter on the 
back, and the belly showing almost white ; the head exactly the same as the 
above, except that the white band on the fore-head is -wider. 
C. —'Female, still older (Campbell Island), shows an advance in age in 
the above; the mantle is getting white, the back vermiculated. The marking 
on the head, however, shows the same, the fore-head above the white line 
being still dark. The belly has become quite white and the chest vermiculated. 
D. —'Adult female. All the head is now white except for a few brown 
feathers on the top of the head; faint vermiculations on the chest and sides 
of the body; the back is less vermiculated (but still with vermiculations), 
with the olecranal patch and white along the top of the closed wing. The tail 
with the white bases of the feathers extending more towards the tip of the tail- 
feathers, which are still black. 
Diomedea exulans exulans from Chili shows the same constant characters as 
those from the New Zealand area, except that the New Zealand immature seem 
to have the white on the chin and throat better defined and extending further 
down the throat. The white over the bill, behind and above the eye, also 
seems better pronounced in New Zealand birds. 
1. From the dark immature (with white as above) the first change seems 
to be on the belly, which becomes white, with vermiculations. 
2. This white, with vermiculations on the belly, extends upwards towards 
the throat, leaving a very wide dark band on the breast. The back is not 
noticeably lighter. At this stage the tail-feathers are quite blackish, except 
at the base, which is white. 
3. The white belly has now no vermiculation and extends towards the 
under tail-coverts. The dark band on the chest is narrower and lighter. The 
nape and mantle are lighter ; the fore-head and back of head also lighter. 
4. The belly and under tail-coverts are white as are the thighs. The 
band on the breast is white with vermiculations, as is the back, which is heavier
