In the following pages I have endeavored to describe 
the incidents of a trip to those comparatively little-known 
islands, the Macpa.ens, with a view to the study of their 
Ornithology. 
I have often thought that if collectors would give a 
summary of the results of their expeditions, naturalists 
would soon be able to estimate the geographical range of 
many species which at present we know very little about. 
In Part Second I have given a list of the species, with 
notes, that were taken or observed. 
Several of the specimens differed in a marked manner 
from their usual coloration; but while giving the points 
of difference in the notes regarding them, I have felt that 
it would be too great a risk to. describe them as varieties, 
as of late years more than half of the “new birds” have 
hardly received their names before they have sunk into 
synonymes, thus greatly impeding science.
