afterwards 3 twelfths; the coeca, i i, 6 twelfths long, 3 twelfths broad, 4 

 inches from the extremity; the rectum, ij k, for 3 inches has a width of 4|- 

 twelfths, and terminates in a globular cloaca, k, 1 inch 10 twelfths in width. 



The trachea is 1 1 inches long, from 5^ twelfths to A\ twelfths in breadth, 

 considerably flattened; its rings moderately firm, broad, 138, with 2 addi- 

 tional half rings. Bronchi of moderate width, one with 20, the other with 

 22 half rings. Lateral muscles large, as are the sterno-tracheal slips. 



This species has a slender trigonal bone 10^ twelfths in length, articulated 

 to the crest of the occipital bone. The anterior part of the cerebrum tapers 

 to a point much in the same manner as in the Turkey Buzzard, forming a 

 similar lobe, 4 twelfths in height at its base, from the extremity of which 

 comes off the olfactory nerve, which is about the 5th part of a twelfth in 

 breadth, runs a course of half an inch along the septum of the eyes, and is 

 distributed to the membrane of the nasal cavity, which is of a triangular 

 form, 6 twelfths in length, 5 twelfths in breadth, with a single large tur- 

 binated bone. The external aperture of the nostrils is completely obliterated, 

 its place being filled by bony matter. The large branch of the 5th pair of 

 nerves passes in its usual direction to the anterior part of the upper mandible.

The Florida Cormorant seldom goes far out to sea, but prefers the 

 neighbourhood of the shores, being found in the bays, inlets, and large 

 rivers. I never met with one at a greater distance from land than five 

 miles. It is at all seasons gregarious, although it is not always found in 

 large flocks. The birds of this species never suffer others of the same genus 

 to resort to their breeding places, although they sometimes associate with 

 individuals belonging to different genera. The P. Carbo appropriates to 

 itself the upper shelves of the most rugged and elevated rocks, whose bases 

 are washed by the sea; P. dilophus breeds on flat rocky islands at some 

 distance from the shores of the mainland; and the Florida Cormorant nestles
