very curious peculiarity of the stomach e, is, that in place of having its
axis continuous with that of the oesophagus or proven triculus, it bands
to the right nearly at a right: angle. It is a very powerful gizzard, 84

which is I I twelfths long. The co;ca are twelfth in length and
twelfth in diameter. The . entire length of the intestine from the
pylorus to the anus is SI inches; (in another male 31) ; its greatest

The trachea is 2 inches 2 twelfths long, of uniform diameter,

other species of the Passerinse or Fringillidas.
In a female, the oesophagus is 2 inches 10 twelfths long ; the intestine
81 inches long.
In all these individuals and several others, the stomach contained
a great quantity of particles of white quartz, with remains of seeds ;
and in the cesophagus^f one was an oat seed entire.
Although this bird is in its habits very Simila» to the Crossbill®,
.'(lid feeds on the same sort of food, it differs from them in the' form
and extent of its crop, in having the gizzard much larger, and the intestines
more than double the length, in proportion to the size of the
bird.
