PSILORHINUS MORIO, Gray. 
Pica morio, Wagler, Isis, 1829, vii, 751.— Ib. Isis, 1831, 527.— Voyage de la Favorite, V, 1839, 54. Said to have 
been killed at San Francisco, Cal. by Botta. 
Psilorhinusmorio, Gray, List, genera, 1841, 51.— Bonap. Consp. 1850, 381.— Cab. Mus. Hein. 1851, 226. 
“ Picafuliginosa, Lesson, Traite d’Orn. 1831, 333.” 
Psilorhinus mexicanus, Ruppell, Mus. Senck. 1837 ; pi. xi, f. 2. 
Sp. Ch. —Tail much graduated ; the lateral feathers about two inches shortest. Second quill equal to the secondaries; third 
and fourth longest. General color dark smoky brown, becoming almost black on the head ; the breast brownish gray ; nearly 
white about the anus ; under tail coverts tinged with brown ; the exposed portion of the tail with a decided gloss of blue ; bill 
and feet, in some specimens, yellow, in others black. Length, 16.00 inches ; wing, 8.00 ; tail, 8.25 ; tarsus, 1.80. 
Hah. —Rio Grande valley of Texas southward. 
The difference in the color of the bill appears to be independent of sex. The feet of the 
yellow-hilled birds are not of the same pure yellow. 
The Psilorhinus mexicanus of Riippel is described as having white tips to the tail feathers ; 
of these there is no trace in the adult specimens, male and female, before me. He speaks of a 
supposed young bird sent from Tamaulipas, by Lindheimer, as being without these white tips.
