tracts to 5 twelfths. The proventrieulus is 8 twelfths in breadth, its 

 glands very numerous, cylindrical, 1^ twelfth long, ^ twelfth broad. 

 The stomach is round, little flattened ; its muscular coat rather thick, 

 composed of a single series of strong fasciculi ; the tendons round, 4J 

 twelfths in diameter ; its inner coat soft and smooth. The intestine is 

 19| inches long ; its width at the anterior part 4 twelfths, toward the 

 coeca 2^ twelfths ; in the rectum 5 twelfths ; the cloaca very large and 

 globular. The coeca come off at the distance of 3^ inches from the ex- 

 tremity, and are only 1| twelfth long, and f twelfth broad. 



The trachea is 3^ inches long, much flattened, the rings, 88 in num- 

 ber, feeble ; its breadth pretty uniformly 2^ twelfths, but at the lower 

 part 2 twelfths. The bronchi are rather slender, with about 15 half 

 rings. The lateral muscles are strong, as are the sterno-tracheal, which 

 are directly continuous with them, and there is a slip which runs down 

 to the last ring of the trachea on each side.

I continue of the same opinion as before respecting the American 

 Goshawk, considering it as in no respect different from that of Europe, 

 notwithstanding all that has been said to the contrary by authors, who, 

 I am convinced, never studied its habits. Some, who at one time con- 

 sidered them identical, now view them as distinct, without so much as 

 informing us on what grounds ; while others adduce characters neither 

 permanent nor general. 



I regret, that although Mr Swain son has described specimens of 

 this Hawk procured near the Saskatchewan River, Dr Richardson 

 says nothing as to the extent of its distribution northward. Dr Town- 

 send did not meet with it on the Rocky Mountains, or in the Oregon 

 Territory. Its tendency to remain in the northern parts of the conti- 

 nent, so as rarely to extend its winter visits beyond Maryland and the 

 lower parts of Kentucky, affords strong evidence in favour of what I 

 have said regarding its identity with the bird of Evirope.
