PSILORHINUS MORIO, Gray. 



Pica moHo, Wagler, Isis, 1829, vii, 751— Ib. Isis, IS.'il, 527.— Voyage de la Favorite, V, 1839, 54. Said to havo

 " Picttfuliginosa, Lesson, Traite d'Orn. 1831, 333." 

 Psilorhinus mexicanus, Rlppell, Mus. Senck. 1837 ; pi. xi, f. 2. 



Sp. Cii. — Tail much graduated ; the lateral feathers about two inches shortest. Second quill equal to the secondaries ; third 

 and fourth longest. General color dark smokj 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. CO inches ; wing, 8.00 ; tail, 8.25 ; tarsus, 1.80. 



Hab. — Rio Grande valley of Texas southward. 



Tlie 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 Fsilorhinus 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.
