AMERICAN CROW. 479 



of its length ; the cloaca, k I, globular and about 1 inch in diameter ; 

 the coeca small, j, cylindrical, 5^ twelfths long and 1 twelfth in breadth. 



In another male, the intestine is 42 inches long ; from 4^ twelfths 

 to 4 twelfths in width ; the coeca ^ inch long, and 1 twelfth in width. 

 In a third, a male also, the intestine is 41 1 inches long ; and in a 

 fourth 33 inches. This statement shews that the intestine of birds 

 sometimes varies very considerably 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, together with a 

 few particles of quartz. That of another contained a mass of pounded 

 sumach berries. 



The trachea, m o, of the first is 5 inches long, a little flattened, 4^ 

 twelfths in breadth at the commencement, 3| twelfths for 2 inches, 

 near the lower part enlarging to 4 twelfths, and again contracting to 2| 

 twelfths. The inferior larynx, oo, is much compressed, with 2 large 

 dimidiate rings. The rings are broad, firm, 56 in number. The bron- 

 chi, op, op, are wide, of about 15 half rings. The muscles are the same 

 as in the Thrushes and Warblers, there being four pairs of inferior la- 

 ryngeal.

This species does not appear to proceed westward along the coast, 

 beyond the mouths of the Mississippi, where it is, however, abundant ; 

 for, after leaving this place, none were seen on ovu- way to the Texas ; 

 where we found the Common American Crow in great abundance. The 

 Fish Crow is, however, plentiful on the Colimibia River, according to 

 Dr TowNSEND, who brought specimens from that country.
