Order PR0CELLARIIF0RME8 
No. 99. 
Family PROGELLARIID^. 
PTERODROMA MAOROPTERA ALBANI. 
WESTERN GREY-FACED PETREL. 
Pterodboma MAOROPTERA ALBANI Mathews, Austral Avian Record, Vol. I., p. 30, 1912 ; 
Rabbit Island, West Australia. 
ASstrelata macroptera Ogilvie-Grant, Ibis 1910, p. 186 ; Carter, ib., p. 658. 
Distribution, West Australian seas. 
Adult male. Differs from P. m. gouldi in its smaller size and lighter coloration. 
Adult female. Similar to the male. 
Immature, Nestling, Egg, Breeding- seasm. Unknown. 
The discovery of this race is due to the fact that an English collector, 
Mr. G. C. Shortridge, visited Rabbit Island, off Albany, West Australia, and 
investigating a breeding-colony of Little Penguins, found one of the burrows 
locally ascribed to the Penguins to be tenanted by a pair of these birds, hitherto 
unrecorded from West Australia. 
These specimens were recorded by Grant in the Ibis and commented upon 
by Carter. Upon writing to my friend Mr. Tom Carter, he made a trip to Rabbit 
Island, and also procured specimens. 
Upon measuring these they were smaller than my New Zealand skins, and 
careful criticism has enabled me to separate them. They have the grey face of 
the Eastern form and are larger than the Atlantic birds. 
It will be noticed that regarding the preceding race, Sandager and Reischek’s 
accounts of their breeding-times do not agree, Reischek stating that the birds 
come to land in August and lay in September, the young being fuU-grown in 
February, while Sandager writes that they begin to burrow in March, apparently 
laying in the middle of June, and the young leave at the end of Decemlfier and 
beginning of January. 
Apparently the West Australian bird approaches in its habits closely to 
Sandager’s account, as Shortridge’s specimens were taken out of a burrow 
on April 1 9th, 1905, and Carter’s on June 24th, 1911. The type described 
was collected by my friend Mr. Tom Carter.
