 Psilorhinus mexicanus, RIjppell, Mus. Secck. 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, iri some specimens, yellow, in others black. Length, 16.00 inches ; wing, 8.00 ; tail, 8.25 ; tarsus, 1.80. 



Hai. — 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 Fsilorhinus mexicanus of Eiippel 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.
