Тнів very distinct species is an inhabitant of Western Mexico from Sonora to Tehuantepec. It was 
originally described by Swainson from a specimen supposed to have been obtained by Bullock on the 
tablelands of Mexico, but, as Messrs. Salvin and Godman point out (Biol. Centr.-Amer., Aves, i. 
p. 21), this was probably a mistake. 
Mr. W. Lloyd has obtained specimens in the Sierra de Alamos in Sonora, at an altitude of 
3000 feet, in May, and these are in the Salvin-Godman Collection. Grayson has recorded the 
species from Mazatlan, and the Salvin-Godman Collection contains specimens procured there by 
Mr. A. Forrer in December. Іп the Seebohm Collection there are also many examples of 
T. flavirostris obtained by Mr. Forrer at Presidio in Mazatlan in January and again in June. 
Mr. Lloyd has met with the species at Zapotlan, in Jalisco, in June (Mus. Salvin-Godman), and 
Mr. W. B. Richardson has sent specimens from San Blas (May) and the Sierra de Nayarit (June) in 
Tepic (Mus. Salvin-Godman). 
Xantus and Grayson found the species on the plains of Colima many years ago (cf. Lawrence, 
Mem. Bost. Soc, N. H. ii. p. 266), and Messrs. Salvin and Godman have more recently received 
specimens from Mr. Richardson, obtained in the same locality in January, while Mr. Lloyd has procured 
it at Santiago, in Colima, in June. Admiral Markham met with the species near Acapulco (Mus. 
Salvin-Godman), and Mrs. Herbert Smith has procured a young bird at Dos Arroyos, in Guerrero, in 
October (Mus. Salvin-Godman). М. Rébouch obtained specimens at San Juan del Rio (Scl. & Salv. 
Р. Z. S. 1870, p. 550), and in Tehuantepec it has been procured by Xantus, Grayson, and Sumichrast 
(Lawr. Bull. U.S. Nat. Mus. no. 4, p. 11). Ferrari-Perez has also recorded specimens, one of 
which is now in the Salvin-Godman Collection, from Chietla, in the Canton de Chiantla, Puebla, 
where they were obtained in November and December (Proc. U.S. Nat. Mus. ix. p. 132). 
Grayson describes this species as an inhabitant of woods and gregarious in its habits, and he 
says that, in its migrations, it passes from one part of the country to another in quest of the different 
kinds of berries which are its chief subsistence. 
Adult male. General colour above dark cinnamon-rufous, brighter and more chestnut on the 
lesser and median wing-coverts, the greater series slaty-grey, externally washed with cinnamon; 
bastard-wing, primary-coverts, and quills sepia-brown, externally clear slaty-grey, somewhat hoary 
on the primaries, the inner secondaries narrowly edged with cinnamon; lower back and rump pale 
slaty-grey, with a slight wash of cinnamon; upper tail-coverts darker slaty-grey ; tail-feathers black, 
externally washed with dark slate-colour; crown of head and hind-neck slaty-grey, but the former
