than in the male of O. guéanensis. This form appears to inter- 
grade with typical O. gutanensis, 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 ( Ze¢rastes 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 in
