Birds of the Weddell and adjacent Seas. 341 
Weddell (op. cit. p. 144) mentions the Blue Petrel as 
oceurring at the South Shetiands, but later explorers do not 
mention Halobena ceruleafor that group or for the Antarctic 
Regions proper. It would seem that this species is local in 
its far southern range, and is a specially characteristic bird 
of the Weddell Sea. It was not seen at the South Orkneys 
during the summer, nor was it encountered at sea in the 
vicinity of that Archipelago. 
In some of the specimens in the collection the white 
feathers of the forehead shew their dark bases, and thus the 
front presents a mottled appearance. The bill in freshly 
killed examples was cobalt-blue, except the nares and culmen, 
which were black. The feet were cobalt-blue, the webs pale 
flesh-coloured, the claws black.

Banks’s Whale-Bird (and perhaps others of its genus *), as 
has already been stated, when treating of Halobena cerulea, 
was logged during the Antarctic voyages of the ‘ Scotia’ as 
a ‘Blue Petrel.”’ Here, however, the specimens collected 
with such praiseworthy diligence again come to our aid, and 
enable us not only to distinguish between the two species on 
important occasions, but also to extend the southern range 
of this bird from 60° S. (fide Salvin, ¢. e. p. 434, and the 
‘ Antarctic Manual’) to 66° S.+ 
The first specimens, a male and female, were procured 
on February 9th, 1903, when the ‘ Scotia’ was off the edge of 
the pack-ice in 59° 42'S. and 34° 13’ W., or about midway 
between the South Orkneys and Thule I., the most southerly 
* Prion desolatus appears (‘ Antaretic Manual, p. 231) to reach the 
edge of the Antarctic Circle, having been obtained by the ‘Challenger’ 
at the ice-barrier. It breeds at Kerguelen. This bird was not obtained 
by the Scottish Expedition, 
+ In the Liverpool Museum, however, there is a specimen which 
believed to have been obtained by Dr. J. Hooker off Victoria Land in 
70° 8S. This example is recorded, along with yialitis Salklandica, 
Nettion flavirostre, and Podicipes calipareus, as new to Antarctica in the 
‘ Bulletin’ of the Museum (ii. p. 48). None of these species have come 
under the notice of later observers within the Antarctic Circle,
