WHITE-BELLIED STORM-PETKEL. 
Philippi and Landbeck may be the former bird (i.e. 0. gracilis Elliot) or, as 
suggested by Mr. Salvin, Fregetta grallariaF 
It is fortunate indeed that so much has been written about F. grallaria, with 
these birds in front of the authors, as comparison with the type proves them 
to be only subspecifically separable. They, however, differ from F. leucogaster 
in their having the tarsus scutellated, whereas in the latter the tarsus is booted. 
To revert to F. grallaria Vieillot : As I have said, my description and 
figure are applicable to the typical form. The type differs only in being 
sfightly paler, which can be accounted for by its being mounted and 
exposed to the light for almost 100 years. The measurements of the type 
are : ^wing 150, culmen (exp.) 13, tarsus 35, tail (imperf.) 69, middle toe 
without claw 19. 
The measurements of F. segethi are : wing 164-166, culmen 13-14, tarsus 
35-36.5, tail 73-75, middle toe without claw 19-21. 
Otherwise they agree in general coloration, which is a dark plumbeous- 
grey, in having the bases to the feathers of the throat dark, as pointed out 
by Philippi and Landbeck, and in having the toes very short and flattened, 
the claws very short, broad and flattened, and the outside toe longest, the 
middle toe subequal with the inner, and the tarsus scutellated. 
There can be no doubt that they are only subspecies, and the names to be 
used must be — 
F. grallaria grallaria VieiUot, Australian waters ; 
F. grallaria segethi Philippi and Landbeck, off the west coast of 
South America. 
A very puzzling bird is the one noted by Gould {Ann. Mag. Nat. Hist., 
Vol. XIII., p. 367, 1844) as having been procured near the coast of Australia. 
Gould’s description is here given : — 
I have a small Petrel, presented to me by Mr. Dension, who killed it near the coast of 
Australia on his passage to Sydney, in which the nostrU-tube is much more lengthened than 
in any other species, and its apical portion turned upwards or recurved, instead of being 
attached to the bill throughout its entire length as in the other members of the genus. In 
the distribution of its colouring it is very nearly allied to T. tropica and T. leucogaster, and 
it may be a mere variety of one or other of those species ; but the bill, in addition to the 
feature pointed out above, is of a more slender and attenuated form than is observable in 
any other. 
The bird itself is in the British Museum, where I have examined it. It has 
the tube erect as there noted, the feathers of the throat have ligh^t bases, 
the upper tail-coverts are white without black tips, the tail square, the under 
tail-coverts dark; there are stray dark markings on the belly. It disagrees with 
the preceding however in having longer toes, not so much flattened, with 
the claws longer and more spatulate. It recalls Oceanites lineatus Peale, but as 
the basal phalanx of the middle toe is longer than the remaining joints and
