Lesson's description and figure of this species Ave re based upon a male specimen 

 supposed to have come from Paraguay, and until a difference was recognized between 

 the Mexican and Guatemalan birds the name was applied in common to both. Gould, 

 however, in his ' Introduction to the Trochilidse,' pointed out the slight distinction 

 separating the two birds, and applied Lesson's title to the Guatemalan foi-m, using 

 Lichtenstein's name S. curvipennis for the Mexican. In this course he has been 

 followed by subsequent writers ; but it is rather doubtful if he was right in so doing ; 

 for if the colour of the' central tail-feathers goes for anything, Lesson's figure repre- 

 sents the Mexican rather than the Guatemalan bird. The point is of slight 

 importance, and we adhere to the assignment of these names as adopted by Gould. 



S. pampa is limited in its range to the great forests of Northern Vera Paz, where it 

 is not uncommon at an elevation of about 1500 feet above sea-level. On one occasion 

 a specimen was obtained near Cohan in November 1859 *, but it was an exceptional 

 circumstance to find it at so high an elevation as 4300 feet.

The first specimens of this bird to receive a name were sent from Mexico by Deppe 

 and briefly described by Lichtenstein in his Price-list of the Duplicates of that 

 collector's spoils. The species is now known to be common on the slopes of the 

 mountains of Vera Cruz from Jalapa to Teotalcingo. De Oca says that it is found in 

 the dense bush near Coatepec in winter, and also occurs in similar places near Cordova
