AUSTRALIAN YELLOW-WEBBED STORM-PETREL. 
twittering of the bird within. They are often quite inaccessible without a rope, 
even when located, but, on the other hand, they may be almost on level ground. 
“ The flight of the bird is peculiarly attractive in these barren waters of 
snow and rock, chiefly perhaps from its resemblance to the flight of the familiar 
martin, for it flits here and there exactly as though in search of insects on the 
wing. Occasionally it sails on outstretched wings. The power of flight must 
be very wonderful, for it seems to spend its lifetime on the wing. On more than 
one occasion it was seen by sledging parties on the ice plain of the Great Barrier, 
some sixty miles from open water (78° 30' S. lat.), but always on the wing, and 
apparently never tired. 
“ Its food, consisting of minute crustaceans, is picked up from the surface 
of the water, on the wing. Flitting about from wave to wave, the little Petrel 
delicately treads the water to steady itself a moment, while it picks up a tiny 
morsel. 
“ As we left the southernmost area, we saw it each day from February 19th 
to March 3rd, but on that day, when amongst the Balleny Islands, we saw the 
last of the icebergs and with them the last of Oceanites. 
“ Five days later on, when in S. lat. 61°, we fell in with Cymodroma gr allaria 
and from that time onwards they became more and more abundant, and 
apparently took the place of Oceanites^ 
The male bird figured and described is the type of 0. o. exasperatus, and 
was obtained at sea off New Zealand. 
Procellaria oceanica was described by Kuhl (1820, p. 136) as follows: —

No locality is given for the specimen described, but inasmuch qs Kuhl 
accepted Banks’s (that is, Solander’s) name and Parkinson’s drawing as repre- 
senting his species, we may accept the locality of that specimen, viz. South 
Atlantic Ocean, off the mouth of the Rio de la Plata, as the type-locality of 
Kuhl’s Procellaria oceanica. 
The description prepared by Solander I give herewith : —
