216 GENEBA AND SPECIES. 



figures a species under the title of Trochilus 

 orthura, described in the Naturalist's Lib. Or- 

 nith. vol. ii. p. 60, pi. 8, as the " Even-tailed 

 Amethystine Humming-bird." It appears to 

 us to be the female of 2V. amethystinus, or per- 

 haps even of Duponti. We suspect that on 

 revision the genus Tryphcena, as it stands at 

 present, will require some modification. All the 

 species in G-ould's cabinet. 



G-enus ATTGASTES, G-ould. 



Male and female beautiful. Beak straight 

 and rather short ; wings moderate ; tail even. 



Grorget splendid, ending in a free pendent 

 point. There is a brilliant forehead-spot in the. 

 males; the chest, below the gorget, is orna- 

 mented by two buff crescentic marks meeting 

 each other at the median line, one being on each 

 side of the chest. 



Trochilus superbus, Vieill. (TV. scutatus 

 Temm.) This superb species is described and 

 figured in the Naturalist's Lib. vol. i. p. 110, 

 pi. 14, under the title of Natterer's Humming- 

 bird. 



Locality : Brazil. In Grould's cabinet. 



Trochilus Lumachellus, Lesson. (Augastes 

 Lamachellus, Grould.) 



This is a most gorgeous species. The head is 

 velvet-black, whence a black mark descends 

 incircling the gorget, with a border of intense 

 ruby feathers below, forming a sort of necklace.
