A young male, passing to the adult plumage, is in Mr. Rothschild’s collection. It is nearly 
velvety black like the adult, but still retains a considerable amount of the first plumage, which must 
have been like that of the adult female. The metallic inner secondaries, when first developed in 
the male, appear to be of a deeper blue than in the adults, while the metallic patch above the eye seems 
to be more purple than in the full-plumaged male. 
The Plate represents an adult male and female of the size of life, and the figures are drawn 
from the type specimens kindly lent to me by Mr. De Vis. The descriptions are taken from the 
specimens in the Tring Museum, and for the opportunity of describing them I have to present my 
best acknowledgments to the Hon. Walter Rothschild.
