10 HUMMING-BIKDS. 



[Case 7.]* 

 LAMPROL^EMA. "Gaenet." 



One of the most beautiful of the Humming-birds, and the sole repre- 

 sentative of the genus to which it belongs. The brilliancy of the throat 

 and breast are remarkable. It is found only in Central America, from 

 Mexico to Guatemala. 



[Case 8.] 

 OREOTROCHILUS. " Hill-stabs." 



Inhabitants of the Andes from Ecuador to Chili ; they are generally 

 found on volcanic mountains, just below the line of perpetual snow. 

 They hunt for insects on the ground among the moss-covered clumps, 

 but desert these when flowering shrubs are out. The females are less 

 brightly coloured than the males. 



Six species are known : — 0. chimborazo from the volcano of Chimborazo 

 in Ecuador, altitude 14,000 feet ; 0. jpichincha from the neighbouring 

 volcanoes of Pichincha and Cotopaxi ; 0. estellce from Bolivia and Peru ; 

 0. leucopleurus from the Chilian Andes ; 0. melanogaster from Peru ; 

 and 0. adelce from Bolivia. All these species are exhibited. 



[Case 9.] 

 LAMPORNIS. "Mangos." 



The tail is only slightly forked, and remarkable for its metallic 

 colouring. The females are less brightly plumaged than the males. 

 Eight species are known, the majority of which are very common in 

 the localities in which they occur. They are found in the West-India 

 islands, and range on the opposite mainland from Mexico throughout 

 Central America to Venezuela, Colombia, Guiana, and Eastern Brazil. 



[Case 10.] 

 EULAMPIS. " Caeibs." 



The tail in this genus is even or rounded, and the upper tail- coverts 

 are very conspicuous, broad, resembling plates of shining metal. The 

 feathers of the forehead project, partly covering the nostrils ; but per- 

 haps the most striking character is the absolute similarity of the sexes, 

 the female being as brightly coloured as the male. Two species are 

 known, from some of the West-India islands, viz. S. Thomas, 8. Croix, 

 Nevis, Martinique, Dominica, and Santa Lucia. 



[Case 11.] 

 LAERESNAYA. " Velvet-beeasts." 



Rather strongly-built birds, with very slender curved bills and 

 metallic-green breast, which strongly contrasts with the black abdomen.
