Adult female—Description of Australian specimen : “The skin shows slight 
whitish tips to back feathers ; whitish bases to throat feathers show as an obscure 
whitish patch ; the belly mark distinct but ill defined ; lower tail-coverts have 
long black tips with white bases and extend to tip of tail ; there is a whitish patch

Ocean, Indian Ocean and New Zealand Seas. F’. t. tropica (Gould) inhabits the 
Atlantic Ocean ; I’. t. melanogaster (Gould) from the South Indian Ocean has a 
white spot on the throat and a mesial dark abdominal line ; F. t. australis Mathews, 
from New Zealand seas, like the preceding as to coloration, but larger size and 
longer legs. 
13. Fregetta tubulataa ALLIED STORM-PETREL. 
Not figured anywhere. 
Fregetta tubulata Mathews, Birds Austr., Vol. IT., pt. 1, p. 42, May 30th, 1912, ex Gould MS. : 
“ Near the coast of Australia ’’ = Locality unknown. 
DistTRIBUTION.—Not known. One specimen preserved in the British Musenm. 
“‘T have a small Petrel, presented to me by Mr. Denison, who killed it near the 
coast of Australia on his passage to Sydney, in which the nostril 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 7’. tropica and 7’. 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.” (Gould.) 
The bird itself is in the British Museum, where we have examined it. It has 
the tube erect as there noted, the feathers of the throat have light 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,
