seen as yet in Costa Eica or the more southern States of Colombia. The remaining 

 five species have all a more or less limited range. B. eximia is found in Colombia 

 alone, B. chloronota and B. edwardd in Ecuador, and B. montana in Bolivia. The 

 species of voidest range is B. cucullata, vi'hich is found in Colombia, Ecuador, and in a 

 slightly modified form in Peru. 



The genus Buthraupis is evidently allied to true Tanagra ; but most of the species 

 are of a more robust build, and have a stronger and stouter bill, with the usual sub- 

 terminal notch very distinct ; the vpings are rather long, the second, third, and fourth 

 quills being the longest in the wing ; the tarsi are stout, but the toes rather short. 

 The sexes are alike in coloration, in which dark blue and bright yellow are the chief 

 colours,

This is a well-marked species of the genus Buthrawpis, of which it is the smallest 

 member except B. edwardsi of Western Ecuador, to which it has no great resemblance 

 in coloration. In this respect it is more like the large B. cucullata, but the head, 

 instead of being black, is of the same colour as the back, and the under surface is 

 deeper yellow. 



Buthraupis arccei is evidently a rare bird, having a very limited range. The only 

 specimens we have seen are those obtained by our collector Arce, who shot the types in 

 the Cordillera del Chucu, and afterwards a few additional specimens in the neighbour- 

 hood of Calobre. 



Of the habits of this bird we know nothing.

Three species only out of twelve or thirteen constituting this genus are found in 

 Mexico and Central America : of these, Tanagra abbas alone is peculiar to the region. 

 Of the others, T. palmarum ranges from Costa Eica over nearly the whole of Tropical 

 South America, and T. cana, with a more extensive range within our country, passes 

 southwards to Ecuador and Venezuela. The other species of the genus are wholly 

 South-American, none being found in the West-Indian Islands except Trinidad and 

 Tobago.
