behind the eye. Specimens from Ecuador and Venezuela have the black postocular 

 patch the smallest, and the palest and greyest crown. Costa-Eica and Panama 

 examples agree very closely with Colombian and Bolivian ; but the crown is rather 

 more tinged with reddish orange. The difference is too slight to justify the separation 

 of these birds ; and we prefer to look upon Basileuterus bivittatus as a widely ranging 

 somewhat variable species. Its range in altitude is probably not great, but restricted 

 to about 3000 or 4000 feet above the sea-level. As we have never yet received 

 specimens from low-lying land, the forests of mountain-slopes are its home. Fraser, 

 who obtained specimens at N^negal (4000 feet)^ and elsewhere, says^ that the irides 

 are white, the bill nearly black, the legs and feet flesh-colour, and that it is a pretty 

 songster. D'Orbigny, who found it at Carcuata in Bolivia, says that it inhabits the 

 wooded ravines of the eastern cordillera of La Paz, and that its habits somewhat 

 resemble those of the Tits (Paridse). Tschudi, who met with it in the sugar-plantation 

 of San Pedro near Lurin, Peru, says that it has a short, intermittent, but loud song. 

 Of its habits in Central America we have nothing to record ; several of our references 

 given above i° ^^ merely refer to Mr. Lawrence's description of B. melanotis.

Though many of the sixteen birds described as from Texas by Giraud have been 

 found within the borders of the United States, B. culicivorus (included by that author 

 as B. brasieri) is not amongst them, and its Texan habitat remains to be confirmed. Its 

 northern range does not, so far as we know at present, extend beyond the temperate
