Santiago de Veragua and Cordillera de Tole. 



As in the case of Eiiphonia annce, Mr. Cassin's description of this 

 bird has several months priority over mine. In comparing the 

 species with B. castaneiceps, Scl. P. Z. S. 1859, p. 441, I have, I 

 believe, indicated its true affinity. These two species constitute a 

 very marked section of the genus Buarremon, which comprises seve- 

 ral distinct groups. 



^' 55. Buarremon brunneinuchus (Lafr.). 



Santiago de Veragua ; Cordillera de Tole. 



Though strictly an inhabitant of mountainous regions, this species 

 is remarkably constant in its characters, specimens from Mexico, 

 Guatemala, Costa Rica, and Ecuador not differing in any appreciable 

 degree.

Two male specimens from Santa Fe have a slightly fulvous tinge 

 on the under plumage, and more than is usually noticeable in Gua- 

 temalan specimens of this bird. This is, I have little doubt, the bird 

 Mr. Lawrence has separated vinder the name of S. intermedins. In 

 our article on the " Birds of Panama," Mr. Sclater and I united this 

 bird with S. mayndides ; but INIr. Lawrence, in his list of Mr. Hicks's 

 Chiriqui collection (Ann. N. Y. Lye. viii. p. 175), maintains the opi- 

 nion he formed as to their distinctness. The question at issue con- 

 cerns the constancy of the characters Mr. Lawrence points out. 

 They are as follows : — (1) In intermedins the feathers of the occiput 

 are mingled with olive-green, (2) the white of the throat extends to 

 the chin, (3) the fulvous of the throat is less bright but twice as ex- 

 tensive, (4) the black band of the chest one-third as wide as in the 

 magndides, (5) under plumage tinged with fulvous instead of clear 

 cinereous, and (6) the crissum darker. I have before me eleven 

 specimens from Guatemala, two from Costa Bica, three from Vera- 

 gua, and three (two males and a female) from Panama, in all nine- 

 teen specimens. (1) All specimens have olive-green feathers on the 

 occiput ; but in Guatemalan specimens the remaining feathers are in 

 general (not in all specimens) blacker. (2) In several of our Guate- 

 malan specimens the white of the throat extends to the bill, in others 

 it does not, nor does it in one of the Panama specimens. (3) As re- 

 gards the brightness of the fulvous of the throat there is a consider-
