that particular species was obtained by Mr. Willoughby Lowe 
during his first visit to the Colony in 1911, while Lowe ii. 
signifies that the bird was obtained by him daring his recent 
visit in 1920. 
Anyone checking this List must remember that nomen¬ 
clature is in what may be termed a transition stage at the 
present time, and in consequence many of the names used 
by Kemp in 1905 and by myself in 1912 have been rejected 
in favour of one we now know to be more correct. All old 
references are included, but often under a different name. 
The specific nomenclature has been carefully revised and 
brought up to date, but individual judgment in accepting 
new names or discussing old ones has, in certain cases, been 
exercised by the writer.
