PSILORHINUS MORIO, Gray. 
Pica morio, Wacten, Isis, 1829, vir, 751.—In. Isis, 1831, 527.—Voyace de la Favorite, V, 1839, 54. Said to have

Psilorhinus mexicanus, Riipreit, Mus. Senck. 1837; pl. xi, f. 2. 
Sp. Cu.—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, 8.90; tail, 8.25; tarsus, 1.80. 
Hab.—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-billed 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.
