OF THE TRUMPETER BIRDo 
527 
The very peculiar cry of this bird has long been known 
to naturalists. When caressed, the living individual, from 
which this description is taken, uttered a deep basso sound, 
which may be tolerably represented by the syllables 
out, out, oHi, and which seemed to proceed from the inte- 
rior of its body. This cry was occasionally preceded by a 
shriller note, which appeared to proceed from the mouth ; 
but it was almost always followed by the deep internal 
sound above mentioned, that may be considered as the 
ordinary voice of the bird. During its emission, the man- 
dibles v/ere slightly separated, and the muscles of the belly 
were observed to be thrown into strong action, though 
without any convulsive effort. 
It can only be from inattention that any naturalist could 
describe the sounds as emitted per anum, an idea from 
which the bird has derived its absurd trivial name. This 
appellation I would propose to change for a more suitable 
name, viz, PsopMa loricata, or P, clypeata^ in allusion to 
the breastplate or shield of beautiful feathers^ so conspicu- 
ous on this bird. The voice is formed within the body, 
and seems to proceed from its interior; so that the Psophia 
may be considered as a true ventriloquist. 
Though the extraordinary sounds emitted by the Trum- 
peter have attracted notice, I am not aware that any ana- 
tomist has hitherto investigated the structure of its organs 
of voice. I therefore readily availed myself of the first op- 
portunity of examining its internal structure, and have found 
my first observations confirmed, after the interval of a year, 
by two other dissections. 
On carefully dividing the ribs, and raising up the ster- 
num, the respiratory organs were exposed to view ; and I 
soon perceived that the' bronchial tubes, instead of being 
united all round to the lower end of the trachea, so as to 
form with it continuous tubes, had each a considerable
