Australian Birds in the Collection of the Linnean Society. 257 
original name of any species. The present case seems to be 
one where we are called upon to risk such an alteration. Out 
of numberless birds of this species which have come under our 
observation, we have seen none in which the colour of the head 
was not the same as that of the bird before us, a grayish-brown. 
The white-headed specimen which Dr. Latham figured, and 
from which he derived the name of leucocephala, appears to be 
not a typical individual of the species, but an accidental, or, as 
far as is hitherto known, an unique variety of it. Even still we 
should adhere to an established name, however strictly inappli- 
cable to an entire group, if the original describer had named the 
species from an actual specimen. But in the present instance 
we find that Dr. Latham's figure and description are taken from 
a drawing. We shall not, however, deprive this beautiful bird 
of its original name without assigning it a better. And in pro- 
posing the present alteration, we hope the venerable Father of 
Ornithology will pardon us for the liberty we have taken, and 
accept this slight tribute of gratitude for the valuable assistance 
which his labours have afforded us in our ornithological studies. 
Mr. Caley calls this species Red Diamond Bird,—the colonial 
name : he met with it occasionally, but not in abundance. He 
is not aware of its habits.
