have all yet to be obtained, and probably four or five other perching 
birds and Petrels still remain to be discovered. 
The least satisfactory part of this Catalogue is, I am afraid, the 
geographical distribution of the genera and species, for such information 
is difficult to obtain in a Colony. The nomenclature of the species, 
except in one or two doubtful cases, such as Larus Jamesoni, will, I 
trust, be found to be tolerably correct ; but for this I, in common. with 
all naturalists in New Zealand, am deeply indebted to Dr. O. Finsch, 
without whose labors it would have been impossible, out here, to have 
corrected many of the mistakes which have gradually crept into our list 
of Native Birds.
