Habitat. Cochabamba in Bolivia. 



I possess a bird of this genus from Peru, with a more truncate form of crest than that of L. Regiilus, the fine 

 feathers of which are rather largely tipped with spangles of dark green. This may probably prove to be, and I 

 believe is, really distinct ; I have consequently proposed for it the specific name of lophotes. In size and colouring 

 it very closely resembles the L. Regulus, with the exceptional difference in the form of the crest.

Mr. Fraser, who killed an example at Zamora, in Ecuador, states that the irides of this species are black, 

 and its mandibles reddish flesh-colour, with a black tip ; he adds that it was feeding from a large Guarumba tree. 



142. LoPHORNis Helena . . " VoL III.PL 123. 



Habitat, Guatemala and Southern Mexico. 



Mr. Salvin states that this species is not uncommon in the vicinity of Coban, and that its cry " is peculiarly 

 shrill and unlike that of any other species I know ; hence its presence may be noticed if only the cry of a passing 

 bird be heard. It feeds among the Salvia that so abound in the mountain-hollows about Coban ; and it is said also 

 to show a partiality for the flowers of the Tasisco when that tree is in full bloom in the month of December. In 

 the month of November females of this species are very rare. Of the specimens I collected, there was only one 



female to seventeen males. 



'* In the Indian language of Coban, Lophornis Helence has, besides the name ' Tzunnun,' which is applied to all 

 the small Humming-Birds, the additional name of ' Achshuhub: The Spanish name is ' El Gordon Cachudo '—the 

 Horned Humming- Bird."— /5i*, vol. ii. p. 268. 



Although I have placed all the species known by the trivial name of Coquettes in the genus Lophornis, the 

 L. chalybeus and L. Verreauxi have been separated by M. Cabanis into a distinct genus, under the name of Polemistria. 



Genus Polemistria, Cab. 



These birds, as will be seen on reference to the plates on which they are represented, vary considerably from 

 all the true Lophornithes ; the feathers of the neck-frill are very diff'erent, and the tail is much longer and more 

 rounded. I shall not be surprised if another species of this pecuUar form should be discovered ; for I have in my 

 possession the skin of a female from Bogota, which I am inclined to think is the female of an unknown species.

Lophornis Verreauxi VoL III. PL 125. 



Habitat. Peru. 



I shall now proceed to the single species of the genus Discura. The band which crosses the lower part of the 

 back alhes this bird to the Lophornithes on the one hand, and to Prymnacantha and the Gouldice on the other. 



Genus Discura, Bonap.
