Type (by original designation) . . .. Pealeornis maoriana Mathews. 
Small Storm-Petrels with short bills, long wings, emarginate tails and long legs. 
This genus differs from Fregetta in hawing the tarsus faintly scaled, also

Fregettornis in the different shaped foot and claws. The tarsus is thinner and 
the foot more slender. The rectrices also are narrower.

culmen 12 mm., wing 151 and 153, tail 63 and 64, tarsus 36. 
Nest. Probably in holes. 
Eggs. Probably not distinguishable from the eggs of other Storm-Petrels. Does it breed off Banks 
Peninsula ? 
This bird apparently occurs on Banks Peninsula, where no doubt it breeds. 
The Promontorio orientali given by Bonaparte as the locality of the Astrolab 
specimen, undoubtedly mean Banks Peninsula and not East Cape.
