196 ROSEATE SPOONBILL. 
The heart, g, is remarkably large, being 1 inch and 10 twelfths long, 
1 inch and a half in breadth. The lobes of the liver, h, i, are very large, 
and about equal, their greatest length being 3 inches; the gall-bladder 
globular, 8 twelfths in diameter. One of the testes is 11 twelfths long, 
9 twelfths broad; the other 10 twelfths by 7 twelfths; their great size 
being accounted for by the individual’s having been killed in the breed- 
ing season. 
In a female of much smaller size the cesophagus is 15 inches long ; 
the stomach 2 inches in length, 1 inch and 9 twelfths broad; the in- 
testine 7 feet 7 inches. The contents of the stomach, fishes, shrimps, 
and fragments of shells. 
One of the most remarkable deviations from ordinary forms in this 
bird is the division of the trachea previous to its entering the thorax. It may 
be described as very short, a little flattened, and quite membranous, 
the rings being cartilaginous and very thin. Its diameter at the top 
is 5 twelfths, and it is scarcely less at the lower part, where, half-way 
down the neck, is formed an inferior larynx, /, which is scarcely enlarged. 
The two bronchi /m, /m, are in consequence excessively elongated. 
They are compressed, 5 twelfths in diameter at the commencement, 
gradually contracting to 3 twelfths, and enlarging a little towards the 
end; and are singular in this respect that the rings of the upper fourth 
are incomplete, the tube being completed by membrane in the usual man- 
ner, whereas in the rest of their extent, the rings are elliptical, entire, 
stronger, and those at the lower part united or anchylosed on the inner 
side. The rings of the trachea are 105, of the two bronchi 73 and 71. 
The contractor muscles are feeble and terminate at the lower larynx; 
from which no muscle extends along the bronchi, which, until they 
enter the thorax, run parallel and in contact, being enclosed within a 
common sheath of dense cellular tissue. The bronchi have the last ring 
much enlarged, and open into a funnel, which passing backwards and 
terminating in one of the abdominal cells, is perforated above with 
eight or ten transverse elliptical slits, which open into similar tubes or 
tunnels, opening in the same manner into smaller tubes, and thus 
ramifying through the lungs. 
In the male bird, of which the upper part of the trachea has been 
destroyed, there are in one bronchus 80, in the other 71 rings, 20 of 
the upper rings being incomplete. 
The vertebre of the neck have no resemblance to those of Herons.
