CHL0E08PINGUS.— BUAEEEMON. 317 



obtained by Arce in the volcano of Irazu or Cartago, and since then others have been 

 sent to the Smithsonian Institution from the same neighbourhood. A specimen has 

 also reached us from the volcano of Chiriqui, showing a wider extension of its range. 



The black head with the two conspicuous lines of white on the side running into 

 one another render C. pileatus a species of easy recognition. 



The figure represents one of the types from Costa Eica. 



C. Macula postocularis nulla.

This is another of Arce's discoveries in the higher mountains of the State of Panama, 

 whence he has sent us several specimens. 



It has a near ally in C. flavigularis of Colombia, Ecuador and the Upper Amazons, 

 but differs in being somewhat smaller, the under surface dingy instead of clear cinereous, 

 and in the middle of the throat being whitish. C. semifuscus of Ecuador is another 

 near ally, but differs chiefly in having a darker head and in wanting the yellow throat. 



The specimen figured is a male from Chitra, Panama. 



BUAKREMON. 



Buarremon, Bonaparte, Consp. Av. i. p. 483 (1850); Scl. P. Z. S. 1856, p. 84 

 Chrysopoga, Bp. loc. cit. p. 480. 

 Pezopetes, Cabanis, J. f. Orn. 1860, p. 415. 



The limits of this genus have been very differently drawn by different authors. 

 Bonaparte, who instituted it, at the same time proposed two other genera, both of 

 which are now usually merged in Buarremon. But he included in these several 

 species now considered to belong to the Fringillidae, into which family he placed 

 Buarremon and the others, near Hoemophila, Atlapetes, Pyrgisoma, Fipilo, Sec. Dr. 

 Cabanis, again, restricted Buarremon to B. assimilis and B. brunneinucha, and placed 

 B. albinucha and B. pallidinucha in the genus Atlapetes, and all of them in a sub- 

 family Pitylinoe of the Fringillidae. 



The present arrangement is that of Mr. Sclater, who extended the limits of Buar- 

 remon, ^ making it embrace four sections— (a) Buarremon, (b) Chrysopoga, (c) Careno- 

 chrous, and (d) Pipilopsis. In the 'Nomenclator Avium Neotropicalium ' twenty
