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 h 
twelfths, and terminates in a globular cloaca, k, 1 inch 10 twelfths in width. 
The trachea is 11 inches long, from 5s twelfths to 4£ 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 101 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 fifth 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.

PLATE CCCCXVn.— Male. 
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
