Adult Female. 
The female differs from the male only in having the tints a little duller

In a specimen preserved in spirits, the interior of the mouth is similar to 
that of the Passenger Pigeon ; as is the tongue, which is 8 twelfths long, but 
broader towards the end than in that species. The oesophagus is 5 inches 9 
twelfths long ; its width at the upper part nearly 1 inch ; the crop of the 
same form and structure as in the species above named, and nearly of the 
same size. The stomach is 11 inches in breadth, IT inches in length ; its 
muscles very strong, the left 6 twelfths, the right 7 twelfths thick ; the 
epithelium of horny’ texture, with two concave grinding surfaces. It con- 
tains seeds of fruits. The intestine is 28 inches long ; the duodenum is 6 
twelfths in breadth ; the average width of the rest of the intestine is 3 
twelfths. The coeca are 2^- twelfths long, T twelfth in width ; the cloaca 
very little dilated, its width about 9 twelfths. 
The trachea is inches long, from 3 twelfths to 2i twelfths in breadth ; 
the rings extremely feeble, unossified on the back part, and 90 in number ; 
the last ring of the same form as in the other species, and the muscles are 
similar. Bronchi moderate, of about 15 half rings. 
The brain in these Pigeons is proportionally much smaller than in any 
other bird examined, excepting the Goat-suckers and Cuckoos. 
The Bough-leaved Cordia. 
CORDIA SEBESTEXA, Willd. PeXTAXDRIA MoXOGYXIA, Linn. CORDIACE^, JuSS. 
This plant, on account of its large tubular scarlet flowers, is one of the 
most beautiful of the West Indian trees. I saw only two individuals at Key- 
West, where, as was supposed, they had been introduced from Cuba. They 
were about fifteen feet high, the stem having a diameter of only five or six
