STRUCTURE OF CHAUNA 
little hook-like processes upon them, which serve for the 
firm anchoring of certain muscles. These “‘ uncinate”’ 
processes, as anatomists term them, are also wanting 
in that undoubtedly archaic and ‘“‘ medieval” bird, 
Archeopteryx. Another ancient character has been 
shown by the secretary of the Zoological Society, Dr. 
Mitchell, who has justly likened the coils of the intestine 
to those of a crocodile. It is an odd thing, as showing 
how those who interpret extinct animals may fall into 
unwitting error, to note that the median horn of 
Palamedea leaves no traces of its presence upon the 
skull; whereas the skull of an entirely hornless bird, — 
the Cape crowned crane (Balearica), which we have 
described on another page, has a bony excrescence or 
rather a pair of them on the skull; this would lead the 
naturalist, were he only acquainted with the skull, 
to gratuitously present to the Cape crowned crane a 
pair of rather large horns, and to descant with ap- 
parently well justified inference upon a descendant of 
horned Dinosaurs. As we see, the precise reverse of 
the indications offered by the skull exist. The Pala- 
medea is horned, while Balearica is not. 
These clamorous inhabitants of the Zoo are, as arule, 
to be found in the well filled Eastern Aviary. But 
in the summer months they are sometimes moved for a 
change farther west into open paddocks suitable in size 
for walking exercise. In such a situation and in the 
year 1904 the Chauna bred and reared three young. 
This event happened for the first time in the history of 
the Society, though many pairs have been exhibited. 
THE CONDOR 
The condor, together with the king vulture, the 
“turkey buzzard,” and the Californian vulture, form 
an assemblage of birds which are collectively known 
by the general term of ‘the American vultures,”
