than in the male of O. guiauejisis. This form appears to inter-, 

 grade with typical O. guianensis, and it seems doubtful if it is 

 even sub-specifically distinct, but the material at present avail- 

 able is insufficient to decide this question. 



Range. — Western South America, ranging north into Panama 

 and southwards through the United States of Colombia, Ecua- 

 dor, and Peru to Bolivia. 



Tschudi met with this bird in the Andes of Peru, at an 

 elevation of from 4,000 to 7,000 feet, but he has published 

 nothing regarding its habits.

Range. — Eastern South America, extending north to Bahia, 

 west to Goyaz, and south to Rio Grande do Sul. 



Habits. — According to Maximilian, Prince of Wied, this 

 bird is called Capueira by the Brazilians and closely resembles 

 the European Hazel Grouse (7>/r^i/^j bonasia) in its habits and 

 mode of life. It is never met with in the open country, keeping 

 entirely to the thick woods. In the early part of the year the 

 Capueira is found in pairs, and after the breeding-season the 

 families remain in coveys of from ten to sixteen or more iii
