Adult Female. 



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

 and lighter. 



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 1^ inches in breadth, 1^ inches in length; its 

 muscles very strong, the left 6 twelfths, the right 7 twelfths thick; the 

 epithelium of a 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, \ twelfth in width; the cloaca 

 very little dilated, its width about 9 twelfths. 



The trachea is 4| inches long, from 3 twelfths to 2\ 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 Rough-leaved Cordia. 



CORDIA SEBESTENA, WUld. — PENTANDRIA MoNOGYNIA, IAmi— CoRDIACEJE, JUSS.

 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
