twelfths in the duodenal 
portion, and 4 twelfths in 
the rest of its length ; the 
cloaca, lc l , globular and 
about 1 inch in diameter ; 
the coeca small, j, cylindri- 
cal, 5i twelfths long and 1 
twelfth in breadth. 
In another male, the in- 
testine is 42 inches long, 
from 4-J twelfths to 4 
twelfths in width ; the coeca 
4 inch long, and 1 twelfth 
in width. In a third, a 
male also, the intestine is 
41J inches long ; and in a 
fourth 33 inches. This 
statement shews that the 
intestine of birds some-

ably in the same species. 
In the stomachs of two 
of them were numerous 
seeds of a brownish-yellow 
colour, globular, and 1 
twelfth in diameter, to-

of quartz. That of another 
contained a mass of pound-

flattened, 4J twelfths in 
breadth, at the commence- 
ment, 3| twelfths for 2 
mches, near the lower part 
enlarging to 4 twelfths, 
and again contracting to
