BIRDS OF WESTEllN COLOJIBIA. 1197 



province of Esmeraldas. M. p. folioins appears to be a well- 

 marked race, diflering from M. p. panameoisis, of Panama, 

 Chiriqui, and S."W. Costa Rica, in its darker coloration. The 

 males are much darker rufous above and have the throat 

 and. foreneck of a deeper cinnamon-rufous shade, whilst the 

 females may also be distinguished by their fuscous (less brownish) 

 back, more blackish cheeks, darker ochraceous foreneck, etc. 



M. jp. polioins is apparently confined to the lowlands and foot- 

 hills of the Pacific coast district of Colombia (from the Truando 

 southwards) and W. Ecuador (south to Guayaquil).

Nos. 2803, 3764. d $ ad. Loma Hermosa (4150 ft.), 22.x. ; 

 Siato, near Pueblo Rico (5200 ft.), 21.ix.09.— Wing 98, 95 ; tail 

 96, 94 ; bill 30, 28 mm. 



" Iris red, feet grej", maxilla black, mandible yellow." 



These two specimens as well as several others from Bogotji are 

 undoubtedly difierent from M.p.poliopis. They are much larger, 

 with a stouter, stronger bill ; the forehead is broadly white, 

 bordered posteriorly by a very distinct, black band ; the cinnamon- 

 rufous colour below extends down over the breast, leaving only 

 the middle of the abdomen white, the flanks being mixed with 

 dull earthy brown, while in all the i^aces of M. panamensis the 

 breast and sides are sharply striped with blackish ; the upper 

 parts are of quite another shade of brown, etc. The sexes are 

 alike, whereas there is a marked sexual diiference in the forms 

 of 3£. p)anamensis. 



M. mystacalis inhabits the mountains of Colombia, being found 

 in the Western as well as in the Eastei'n Cordillera (Bucaramanga, 

 Bogota).

No. 2562. 2 ad. Juntas, Rio Tamami (405 ft.), 5.iii.09.— 

 Wing 142 ; tail 132 ; bill 39 mm. 



" Iris dark brown, feet black, bill scarlet." 



A fine example of this scarce species, which is at once known, 

 among the other white-fronted forms, by its black throat and 

 smaller, nearly white upper wing-coverts. It corresponds exactly 

 with Cassin's description and figure.
