272 On a new Finch from Gnatemala. 



now our bows turned down stream, and are at present merely 

 awaiting the rise in the river to float us down to the Paraguay. 

 I am in hopes that we shall be out of the Pilcomayo by 

 the end of February, and I shall at once return to England, 

 with perhaps a week or two's delay in Ascension and Buenos 

 Aires. 



XXV. — On a new Finch of the Genus Pheucticus, /rom Gua- 

 temala. By OsBERT Salvin and F. DuCane Godman. 



During a recent excursion to the slopes of the Volcan de 

 Santa Maria, near Quezaltenango, in Guatemala, Mr. W. B. 

 Richardson obtained two specimens of a Finch of the genus 

 Pheucticus. Both of them are in moulting plumage, but 

 the new feathers of the adult are sufficiently developed to 

 show that this bird is quite distinct from its nearest ally, 

 P. chrysopeplus, of Western Mexico. The presence of a 

 Pheucticus in this district partially fills up a gap in the range 

 of the genus. Hitherto it was supposed to be absent from 

 the wide tract of country lying between Western Mexico 

 and Costa Rica, where P. tibialis occurs, but now the high- 

 lands of Guatemala must be included in its range. 

 We propose to characterize this species as follows : — 



Pheucticus aurantiacus, sp. n. 



Aurantiacus, alis nigris, speculo alari, remigibus internis 

 ct secundariis in pogonio externo ad apicem albis ; in- 

 terscapulio nigro plumis singulis aurantiaco marginatis, 

 uropygio nigro maculato, supracaudalibus nigris albo 

 terminatis ; cauda nigra, rectricibus duabus externis in 

 pogonio interno late albo terminatis, tertia ab externa 

 quoque ad apicem alba, tectricibus subalaribus auran- 

 tiacis, subcaudalibus albis ; rostro nigro, mandibula basi 

 albida. 



^ jr. supra multo magis nigro variegatus, plumis capitis et 

 cervicis posticis medialiter nigris, uropygii nigris au- 

 rantaco terminatis. 

 Hah. Volcan de Santa Maria, Guatemala. 

 Obs. P. chrysopeplo proximus et ejusdem staturse, sed capite 



toto et corpore omnino subtus magis aurantiacis, interscapulio 



nigro variegato, et uropygio nigro guttato distinguendus.
