PROCELLARIA ^QUINOOTIALIS STEADI. 
NEW ZEALAND WHITE-CHINNED PETREL. 
Pbocellabia ^quinoctialis steadi, subsp. n. ; Antipodes Island, New Zealand. 
Majaqueus cequinoctialis Buller, Trans. New Zeal. Inst., 1892, Vol. XXV., pp. 62, 80, 1893 ; 
Hutton, ib. 1894, Vol. XXVII., p. 177, 1895 ; BuUer, Suppl. Birds New Zeal., Vol. I., 
p. 109, 1905 ; Godman, Monogr. Petrels, p. 169, 1908 (pars). 
Adult male. General colour above sooty-black with brown edges ; interramal space only 
more or less white; “ Bill with sides of the upper mandible and the tubes blue, the 
culmen and unguis black, the lower edge of the lower mandible flesh-colour ; legs 
and feet black ” (Hutton). Total length 510 mm. ; culmen 56, wing 388, tail 122, 
tarsus 67. 
Adult female. Agrees in coloration and size. 
Young. According to Hutton, identical in coloration. 
Nest. “ Breeds in holes made in the side of a slope, these holes being hollowed out into 
a eircular chamber at the end ” (Hutton). 
Egg. “ White ” {id.). 
Breeding-season. “December” {id.). 
I HAVE included this subspecies in the Australian List, as there is a specimen 
in the British Museum, supposed to have come from Tasmania, which is 
undoubtedly the Antipodes Island breeding bird. It is a bird which could be 
reasonably expected to be driven as far north as Tasmania, and from the general 
Australian records of Majaqueus cequinoctialis I cannot conclude whether 
P. a. conspicillata is always intended. The inclusion of this bird will draw atten- 
tion to the fact that such a race may be met with. What can be the Majaqueus 
cequinoctialis of Hull {Proc. Linn. Soc. N.8.W. 1909, Vol. XXXIV., p. 649, 1910) 
recorded as a visitor to the seas adjacent to Lord Howe Island? As a synonym 
is given Majaqueus gouldii Hutton, of Ramsay. Ramsay could surely never 
have intended P. a. conspicillata by this identification, and he most probably 
intended Pterodroma 7nacroptera gouldi which is an altogether different bird. 
It will be seen how difficult it is to deal with the existent Australian records 
of birds of this order.
