U. S. P. R. R. EXP. AND SURVEYS-ZOOLOGY—GENERAL REPORT. 
Family PSITTACIDAE. The Parrots. 
The family of parrots is one so strongly marked as to he familiar to every one. The peculi¬ 
arities belonging to it are very many, and the differences from other forms so great as almost to 
warrant its erection into a distinct order, as has been done by Bonaparte, who, in addition, 
places it at the head of his system, separated from the typical Scansores by the rapacious birds. 
The parrots are very extensively distributed throughout the warmer portions of America, 
although the United States includes but a single species, as far as known. A second species, 
Iihynchopsitta pachyrhyncha, 1 inhabits the table land of Mexico, and probably extends to within 
a hundred miles of our frontier. The other Mexican species, according to Sclater, (Pr. Zool. 
Soc. 1857, 230,) are Ara militaris, Conurus petzii and astec, Pionus senilis , Psittaeula lineolata, 
and Chrysotis autumnalis, viridigenalis, and ochroptera. Some of these may extend their range 
northward, and even occasionally occur within our limits. 
CONURUS, Kuhl. 
Conurus, Kuhl, Consp. Psittac. 4, 1830.—In. Nova Acta K. L. C. Acad. X, 1830. 
Tail long, conical, and pointed ; bill stout; cheeks feathered, but in some species leaving a naked ring round the eye; cere 
feathered to the base of the bill. 
The preceding diagnosis, though not very full, will serve to indicate the essential character¬ 
istics of the genus among the American forms with long pointed tails, the most prominent 
feature consisting in the densely feathered, not naked, cheeks. But one species belongs to the 
United States, though, as already stated, two others are found in Mexico, and many more in 
South and Central America. 
1 The following description of this species, taken from Swainson, will serve to identify it, if ever captured within our limits : 
RHYNCHOPSITTA PACHYRHYNCHA, Bon. 
Thick-billed Parrot. 
Macrocercus pachyrhynchus, Sw. Syn. Birds Mex. in Philos. Mag. I, 1827, 439, No. 79. 
Rliynchopsitta pachyrhyncha, Bon. Tableau des Perroquets, Rev. et Mag. deZool. 1854, 149. 
Psittacus pasclia, Wagler, Isis, 1831, 524. 
Sp. Ch. —Green front ; eyebrows and ridge of shoulders red ; cheeks plumed ; tail feathers broad and obtuse. Wing 10 
inches ; middle tail feathers 5.25 ; curve of upper mandible 2.00 ; depth of under mandible 1 inch. Hab. —Table lands of Mex. 
Sw. Syn. Birds Mex. in Philos. Mag. 1827. 
A specimen of this species is in the collection of the Philadelphia Academy of Natural Sciences, labelled Rio Grande, Texas, 
J. W. Audubon. If really taken within the limits of the United States, it is probably of very rare occurrence.
