ALLIED WHITE-BELLIED STORM-PETREL. 
colour and with white bars ; the white feathers on the side of the body lack 
the dark median lines and instead have narrow dark-brown margins ; the 
upper tail-coverts have wide blackish ends, these almost hiding the white 
rump; culmen 13 mm., wing 165, tail 75, tarsus 36. Collected on the 
south-west beach of Lord Howe Island on September 23rd, 1913. 
Another adult female collected on the same island, on King’s Beach, on 
May 16th, 1914, agrees with the type : wing 156 mm., tail 76, tarsus 36, 
culmen 14. 
An immature, with down adhering to the head, also agrees with the type. 
Collected at Mt. Nichols, Lord Howe Island, on May 9th, 1914. Wing 158 mm., 
tail 74, tarsus 36, culmen 13'5. 
These three birds agree in having the white rump almost hidden by blackish 
feathers. It is difficult, at present, to consider them identical with insularis. 
Neither immature or adult of alisteri have the white edges to any of the 
feathers on the upper-surface, thus marking them off from grallaria, which at 
all stages of its career has these white margins to the feathers on the back, 
etc., neither does insularis have these white margins. 
Another specimen which I figure on pi. 8 also agrees in having the inner 
lining of the wings and axillaries as in alisteri. Culmen 14 mm., wing 161, 
tarsus 36 : Lord Howe Island. In my MS. I have called this C. hoivensis. 
In C. grallaria innominata the black head is noticeably marked off from 
the lighter feathers of the back ; the lower back feathers are always narrowly 
margined with white ; the white rump is most pronounced as, also, is the pure 
white inner under wing-coverts ; the black under tail-coverts are margined 
with white at the tips. In alisteri these latter feathers have no white tips. 
After working up these birds again and examining a long series of over 60 
skins, including downy young, I consider grallaria innominata a good subspecies, 
and insularis, alisteri and royana three species. 
I have had drawings made of all these forms and must leave it for future 
workers with more material to settle the standing of these difficult birds.
