to 8 twelfths ; the proventriculus, b c, 
is 5 twelfths in breadth, its glandular 
belt 6 twelfths. The stomach, c d e, 
is a very strong muscular gizzard, 
placed obliquely, of an elliptical form, 
11 twelfths in length, twelfths in 
breadth. The proventricular glands 
are large, nearly globular, J twelfth 
in diameter. The muscular coat of 
the stomach is rather thin, the thick- 
ness of the lateral muscles being 2 
twelfths ; the epithelium dense, tough, 
dark red, with three longitudinal, 
rugae on each side. The contents of 
the stomach are remains of insects, 
larvae, and especially legs of grass- 
hoppers. The intestine, efghij, 
is of moderate length and width, the 
former being 121 inches, the latter 
averaging 2h twelfths. The duode- 
num, ef, curves in the usual manner 
at the distance of If inches, and is 3 
twelfths wide. The coeca, i, come off 
at the distance of li inches from the 
extremity, and are 3 twelfths in 
length, 1 twelfth in width, and ob- 
tuse ; the cloaca, j, is small and of 
an oblong form, its breadth 5 twelfths. 
The trachea is 3 inches long, flat- 
tened, firm, of the nearly uniform 
width of two twelfths. The rings are 
68, with two dimidiate, rather broad 
and firm. There are four pairs of 
inferior laryngeal muscles besides the 
sterno-tracheal, and the lateral mus- 
cles are of moderate size. The 
bronchi are rather narrow, of 18 
half rings.
