This is quite a new bird to me. Mr. Nation sends it as " Pipilo 

 mystacalis ;" and I should have preferred to employ his name, had 

 there not been already a species oi Buarremon with that title attached 

 to it. 



I have had some doubt whether to place this species in the genus 

 Buarremon (where its nearest allied forms are B. gutturalis and B. 

 albinuchus), or among the Finches in or near the genera Pyrgisonia 

 and Atlapetes. The Taiiagridse and Fringillida? (as I have arranged 

 them) come very close at this point ; and I do not pretend to say 

 that the distinction between them is not more or less of an arbitrary 

 nature. On the whole it seems most consonant with structure and 

 geography to arrange this bird amongst the Buarretnones ; and I 

 propose to name it after its discoverer, who has been so long an 

 ardent student of the Peruvian avifauna. 



The bill of B. nationi is rather thicker and stronger than that 

 of B. albinuchus; and its culmen is rather straighter. In its generally 

 cinereous colour and cinnamomeous belly and under tail-coverts it is 

 rather divergent from other species of the genus. 

 Prof. Nation's notes on it are as follows:- — 



" This beautiful bird is found on the western sides of the Cordillera, 

 at an altitude of 10,000 to 14,000 feet. 



" I have received many examples, male and female. The sexes are 

 similar ; the few white feathers on the head are seen in both the male 

 and female, and always present. Food, seeds and coleopterous insects. 

 Total length 8 inches, wing 4. Irides reddish brown." — W. N. 



In our ' Nomenclator ' Mr. Salvin and I assigned twenty species 

 to the genus Buarremon. Since its publication the following ten 

 additional species have been described : —
