GEtfEBA AND SPECIES. 145 



Genus HELIOMASTER. In this genus the 

 beak is long and straight or only very slightly 

 arched ; the feet are small, and the tail ample. 

 The gorget, or throat-plume, is extensive, and 

 produced more or less laterally by means of 

 large pointed feathers. The females are far 

 plainer than the males. 



The types of this genus are, the Trochilus 

 longirostrisofVieillot(Trockilus superbus, Shaw, 

 nee VieilL), described as the Superb Humming- 

 bird in Nat. Lib. Ornith. vol. ii. p. 94) ; and 

 the Tr. mesoleucus of Temminck (Tr. lonyiros- 

 tris, Natter, nee Vieill.), described and figured 

 in Nat. Lib. Ornith. vol. ii. p. 91, pi. 17, as the 

 White-striped Humming-bird. 



The birds of this genus are remarkable for 

 powers of flight. The first species enumerated 

 is a native of the Antilles (Island of Trinite), 

 the second of Brazil. In G-ould's cabinet. 



Mr. Gould separates from the foregoing genus 

 a species to which he gives the generic title of 

 PTEROPHANES. This species is the Trochilus 

 Temminckii, Boiss. nee Less. (Tr. cyanopterus, 

 Loddig.) It is a native of the mountain range 

 of Columbia, and is described and figured by 

 Mr. Grould, in his Monoyr. TrochiL (fig. 7), 

 under the title of " Temminck' s Sapphire-wing" 

 (Pterophanes Temmincki, Grould). 



This species ranks amongst the most gorgeous 

 of the Trochilidte, and is, in particular, to be 

 distinguished by the brilliant colour of its wings.
