Distripution.—Australia (visitor). Breeding on Lord Howe Island, formerly on Norfolk 
Island. One occurrence in Bass Straits. Specimen preserved in British Museum. 
Adult (type of P. solandri Gould)—Back, scapulars, and upper tail-coverts 
slate-grey with dark edgings to the feathers; lesser wing-coverts, bastard-wing, 
and primary-coverts dark brown; primary-quills also dark brown on the outer 
webs and at the tips, paler on the inner webs, and becoming white at the base ; 
median and greater coverts slate-grey, the secondaries similar but pale brown on 
the inner webs and whitish at the base; tail dark brown with hoary-grey on some 
of the outer webs of the feathers, pale on the inner webs and also at the base ; head 
and neck all round sooty-brown, the feathers having white bases give a scalloped 
appearance on the fore-head and sides of face; breast pale sooty-brown, becoming 
dull slate-grey on the abdomen, under tail-coverts, and sides of the body ; the feathers 
on the sides of the body slightly edged with white at the tips like the axillaries ; 
under wing-coverts dark brown, the greater under wing-coverts dull white like the 
base of the primaries ; bill black; eyes dark brown; feet black, web greyish-black. 
Total length 450 mm.; culmen, from base of feathers on forehead, 40, wing 296, 
tail 128, tarsus 41. 
Adult male and female—Alike. 
Immature—We have examined many birds which still retained the grey down 
on the abdomen. These show the characteristic mottling of the face, and agree 
entirely in coloration with the adult, save that the shades appear lighter or darker 
than they do in the adult, owing to the wearing ; thus the secondary wing-coverts 
are lighter, while the median coverts show darker, the lesser again appearing lighter, 
etc. The dark tips to the feathers of the under-surface are somewhat paler. 
Nestling —Covered with dark ashy-grey down, concolour. 
Nest.—A large accumulation of grass in burrows, some as much as six feet in 
length, in which the egg is almost concealed. 
£gg.—Clutch, one; dull white; 63 mm. by 44. 
“They lay but one egg, and that is full as large as a duck’s egg.’ (Hunter, 
Norfolk Island.) 
Breeding-season.—June, July and August. 
“Most of the females taken in May were with egg.” (Hunter, Norfolk Island.) 
Distribution and forms—Breeding at Lord Howe Island only ; only other record 
as above and consequently no subspecies. 
25. Pterodroma inexpectataa—MOTTLED PETREL. 
[Procellaria inexpectata Forster, Deser. Anim., ed. Licht., p. 204, (pref. Jan. Ist) 1844: Seas 
south of New Zealand. Extra-limital.] 
Mathews, Vol. VII., pt. 5, pl. 368, July 10th, 1919.
